Smelting and Furnace Ratios - Factorio Tutorial

[@guido9861]

Thanks, man. You and a thousand other ''just some dude''s doing all this work for the good of a community just makes me happy

[@Xterminator]

My Pleasure! It is a joy to make the content and is even better when I know it helps people. :)

[@raisins7777]

Red belt and steel furnaces are both twice as fast as yellow and stone, so if you upgrade to both at about the same time the footprint of the design stays the same, which is nice.

[@Xterminator]

Yeah that's quite a good point. It makes it a lot easier for sure!

[@TallinuTV]

An underground belt entrance or exit works a lot like side-loading. In the same way that items on the main belt block items on the incoming side belt (adding items to the empty part of the main belt prior to the side loading point will cause them to take precedence over the items coming from the side belt, which won't move until there's a gap on the main belt), items coming up from the underground belt simply get held back until there's room on the aboveground part of the belt. Inserters are able to drop items onto this aboveground portion just before new items are allowed to exit the underground portion, allowing them to take precedence and fully compress the belt. For an underground entrance tile, the process is similar -- the point at which items are sucked underground is far enough back that as soon as that happens, there's enough room ahead of the next items in line for the inserters to drop another item onto the aboveground part of the belt. The inserter-dropped items are able to "cut in line", and as soon as there is room on the underground portion of the belt they will be taken first, finally allowing the blocked items to advance again. Also, you don't have to use underground belt for the early parts of the output belt line, only the last 1/3 to 1/2 of it where inserters may have trouble finding gaps to drop items into. Of course, if you _want_ to spend the slightly extra resources on doing so, there's nothing wrong with that. :)

[@Xterminator]

Great explanation, and spot on! :) I wish I could of explained it that well in the video. Lol Also you did bring up a good point about the underground parts only having to be on the last 1/3 or 1/2 of the belt, that's totally true. For me personally, I would rather spend the extra resources to make it all undergrounds so it's all even and the same. :P

[@jnbsp3512]

Its cool to look back and appreciate inserters can compress better in the current version of the game.

[@lukecoreil3160]

so we dont need to do the underground belt thing?

[@jnbsp3512]

Should no longer be needed. You can read more about it on the official factorio website blog. It is titled Friday Facts #231 - Belt compression & Crash log uploading

[@anialator1000000]

truthfully, You don't round up once, you round up twice, Once per side. You need 46.6 Something for one yellow belt, that is 23.3 per side. That means that 23 on each side would not be enough to completely compress it, so you need 24 for each side, hence 48 is the correct rounding number, not 47

[@Xterminator]

Ah yeah good point, I didn't really think of it that way.Thanks for pointing it out! :)

[@SpecctreFen]

This com is 7 years old and i didn't learn a shit ... Im doing it too lmao.

[@s.sradon9782]

the reason why you use electric foundries, is because you can use bot sides of your input belt to input ore, which is what new players do not understand at first.

[@skandababy]

And more importantly, it's half the pollution.

[@Waldohasaskit210]

If you don't want to spend a ridiculous amount of resources that underground belts take compared to regular belts, you could just move the furnaces one square further away from the center belt and have the insertors feed onto separate belts that then feed into the central belt, fully compressing it.

[@Xterminator]

Yup that would certainly work as well. :) I much prefer the look and ease of using underground belts, but if the cost is an issue in your game then your solution definitely works. Plus, using the way you suggest it can make it easier to upgrade later. ;)

[@satannstuff]

Inverting the stack and sticking a simple ( 1 splitter + 1 extra belt ) lane balancer two thirds of the way down and at the end of each output belt should work as well, this would fill the output lanes to two thirds capacity before each balancer, one third unused capacity should be more than enough to be able to unload all the plates without throughput loss. This also doesn't increase the stack's size.

[@berenscott8999]

Coal running to electric smelting? :P

[@Xterminator]

Yeah woops, force of habit. :p

[@BarcelPL]

Xterminator does this mean you can halve the amount of furnaces per side if you use both lanes for ore?

[@thegreycactus6415]

Barcel no, because it's smelting that's slow, not inserting

[@thetute59]

But wouldnt the belt just be satisfied longer? When you have double the amount of ore incoming? Or what am I getting wrong?

[@game1boy1007]

it's a feature, not a bug.

[@NUKEsTavern]

Thank you so much for making this informational video. This was exactly the information I was looking for and you explained it expertly.

[@gemmel3197]

Thanks for the link to the ratios doco, best one ive seen. Design for the steel was helpful too, thanks

[@Xterminator]

You're welcome, glad it helped! I agree, the document is super helpful, and I love using that steel setup, it works great.

[@MylilPwny85]

Just want to mention that this seems to fit in version 0.17. The numbers have changed, so instead of belt speed (13.333) and smelting/crafting speed (3.5) 13.333*3.5 = 46.66 roundup to 48, we now have belt speed (15.0) and smelting/crafting speed (3.2) 15*3,2 = 48! Easier numbers to work with.

[@Xterminator]

Awesome! Really glad the numbers work out so well now. :)

[@Andrey_27249]

dude your factorio cheat sheet is amazing!! so useful, thank you man so much!

[@AlRoderick]

Here's what I like to do: bring in a full belt of ore, do the two facing splitters to split it into two wings. Then I do furnaces outside, input and output belts in the middle and alternating yellow and red inserters. this gives me two half compressed outputs flowing towards the center, where I can sideload them into a single compressed output. When I upgrade to steel I upgrade the belts.

[@Xterminator]

Nice! That definitely works too. Many different layouts for smelting, which is what I like about it.

[@keksomg]

This series is awesome. Thank you for supporting our laziness :p

[@Xterminator]

Thanks, and no problem, glad to help! :)

[@lolmao500]

Cool. Now we just need to know how many electric drills to full a blue belt

[@Camperglitch_]

Electric Drills have an mining rate of 0.525/s for Iron, Copper and Coal. Stone has 0.65. Therefore you need 77 Miners for Iron, Copper and Coal and 62 Miners for Stone.

[@snugglyjeff214]

Camperglitch everyone always tosses out the numbers, but I have zero idea how they come to that result

[@marcomarques1033]

A simple division between the belt capacity and the output of one miner gives u the total of miners u nee to fulfill the belt.......

[@geniegerny]

If I took something away from this video it's that I have OCD too :D Great video btw explaining how you got those ratios.

[@mytt01]

Found from the reddit post. Very helpful and easy to follow, thanks!

[@Xterminator]

You're welcome, glad it was easy to follow along!

[@thunder852za]

Great video, but even though I want to watch your other explanation videos, I want to keep some of the joy of discovering this stuff myself. :)

[@Xterminator]

Thanks. :) No worries, I would agree with you honestly. It's really fun to just learn some of this yourself. But if you do get really stuck then that's why the videos are here. :)

[@WanderingTimmyGaming]

I'm doing a mass production play through to get all the achievements. This will be really useful for that. Cheers for putting it together, Although I feel an unhealthy obsession with efficiency coming on :)

[@Xterminator]

Nice, that sounds like a lot of fun! :) You're welcome, it was fun to do and it seems to be helping a lot of people out which is great. Lol, yeah getting obsessed with efficiency I think is a natural side affect of Factorio.

[@s.sradon9782]

I don't think undergrounds are needed for full compression anymore, because on my solo game it looks perfectly compressed.

[@Xterminator]

Glad I could be of some help! :) Thanks, Xterm

[@MrJoeDone]

btw having 2 times 36 instead of 35 for the blue belt is not just for looks, you kind of need it, even if the math says something different, you will see one of the two extra ones move once in a while, which wouldnt happen if they where completely useless and just for the looks

[@Gords1229]

I think you forgot to put the links to the ratio information that you mentioned in your video, I'd be interested in having a look at that

[@Xterminator]

Just added it. :) I did forget, but thanks for the reminder!

[@worstenbroodje6832]

But how much do I need to mine to supply the smelters?

[@gilian2587]

Production rate for electric miners is 0.5 ore/second. Yellow belts support around 7.5 items per lane per second... so ideally you need around 15 Miners per lane. Supplying that much is even more of a trick; you need to consolidate multiple ore patches as sources.

[@1Maklak]

When you get to 20+ furnaces per side, I'd rather use 4 or 8 rows of furnaces rather than 2 very long rows, then compress with splitters. This uses up a bit more room, but is easier to fit into factory design. Splitters will also take care or compression, so you won't need the underground belt trick.

[@Xterminator]

This is more personal preference and dependent on your specific factory I'd say. For example, I plan my factories to fit long rows of furnaces so it's not an issue. Splitters can help with compress when combining multiple non-compressed lines, but they also cause issues that create little gaps of non compression sometimes.

[@1Maklak]

Also, if you're doing something crazy like 4 saturated belts of each metal, multiple long rows of furnaces (one row per) belt are probably the best option anyway.

[@MegaBert86]

Thanks for that. Very helpful

[@WhatAboutRC]

Wish you also explained how many miners it takes to keep it going.

[@TheRiffwood]

Is it possible to show the math written out on the video (like on the left side) so we can see your process as you do all your math equations. Plus I think it would be easier for people to follow along especially people like myself who are more visual learners. Just a suggestion even though it is simple math sometimes following along off of just speech can be difficult for some. Regardless the video was great, looking forward to another!

[@Xterminator]

Unfortunately I can't add it into the video itself now that it's uploaded, but I could add in annotations with the numbers/math on them. It won't be as nice looking, but I'll fiddle with it and see if I can make it work because you have a good point. :) I regret not overlaying the math to begin with, but for some reason didn't even think about it. Glad you still liked the video, and look forward to the next, I plan to do a lot more like these!

[@lawlzerderp7136]

Good video, man

[@Xterminator]

Thanks, glad you enjoyed it!

[@ThreadMenace]

Number of drills required to fill a belt would be good addendum to this.

[@JeyJeyKing1]

Gunnar J for copper and iron: Yellow belt 25-26 drills Red 51-52 Blue 76-77

[@lordgrago2058]

Very helpful! Are there any info about how much mining I need to fulfill the needs of furnaces?

[@longshot789]

Do these ratios hold in 0.15?

[@Xterminator]

Yup! :)

[@flora_76]

great video man, thank you

[@Xterminator]

Very welcome! And thank you. :)

[@Loulabelle100]

Didn’t they improve the belt speed to 15. Items per second? So does that mean you need more now?

[@JhAsh08]

That's just in the experimental version of factorio .17. The official version is still .16, where the belt speed is 13.33. But you're right... that change is going to change all the ratios and screw up all of my blueprints, ugh

[@Ashebrethafe]

They also improved the smelting speed to 3.2 seconds per item, so you now need _exactly_ 48 stone furnaces per yellow belt of input (which will make a full belt of iron or copper, half a belt of stone bricks, or a fifth of a belt of steel).

[@cybervantyz]

Would be interesting to see some calculations related to upcoming "science revolution" mentioned in FFF by developers. How much assemblers and stuff will we need to get full belt of new science pack 3, and military, production and high tech science packs.

[@Xterminator]

Yeah that is a great idea! I will most definitely do videos on that once it is released. I wish I could do some now, but the items and stuff required for them is not confirmed yet so it would just be speculation at this point.

[@tomsmiff]

Great video helped me a lot thx :)

[@Xterminator]

Glad it helped! :)

[@dragonpc8258]

Liked and Subbed, great info thank you.

[@Xterminator]

Thank you, and welcome to the channel! Glad it helped. :)

[@ARUCARDFTEPES]

Don't the fast inserters have an effect on the ratios? You're using normal on the iron, but fast on the steel so would fast inserters on the iron not make a difference? Also you have the stack inserter bonus upgrade right? And how will the update to belts effect this ratio? -I didn't even mean to watch this video, it was featured on your page, but it was good and I thought of those questions. :D

[@Xterminator]

Good questions. The inserters shouldn't really matter actually, aside from maybe inserting onto or taking from a blue belt. You might want faster inserters for that. The stack bonus also shouldn't matter much for the ratios. I don't believe the belt changes will effect these ratios because as far as I know the changes are pretty much behind the scenes stuff for optimization.

[@ARUCARDFTEPES]

I see, basically they're still limited by how fast the furnaces smelt right? Well I'm glad people like you enjoy figuring these things out and sharing it, people like me could never understand it on our own, so thanks for the help!

[@a.e.richardson218]

incerters can fully compress a belt but only after stack size increse

[@matsv201]

There is some flaw here... On the electric furnaces there is coal on the belt... Of cause if you would run both sides of the belt on bot upper and lower smelters, it would overfill the belt, so then a additional belt would bee needed in the middle, also with belt balancing.

[@Xterminator]

Yeah it was just habit, I forgot to remove the goal input from the electric furnace belt. :P The ratios are are still correct though. Main difference is that you would have a full belt of ore on each side rather than split half of coal and half of ore.

[@matsv201]

But then there is really two options. Go for Two belts between each and make really long column, or do one between them and let them share. There is also a other bit. Specially when going for blue belt. Its kind of a waste going for blue belt all the way. Can reduce it quite a lot by using blue belt for just a bit, change to red, then change to yellow.. and do the opposite on the output.

[@KrossFire330]

learned alot fromm this, thanks

[@Xterminator]

Thats great to hear, you're very welcome!

[@darkfrei2]

Nice idea with underground belts!

[@skullkrusher4418]

I'm more concerned about the number of furnaces that can be fed by an input belt. Like, aren't some of those furnaces not being fed with iron ore? How do you fix that and still get full compression on the red belt.

[@anonanon352]

You only need underground belts for the furnaces at the end. 4 underground belt total, 2 pairs, for the yellow belt. One pair for steel / electric furnaces on yellow belt. Also, you mentioned a comparison of steel and electric furnaces, so I thought I'd give the results of my math. With no modules and no solar panels, and taking into account the power consumption, pollution, and inefficiencies of the furnaces, the boilers, steam engines, the mining drills on the coal, everything, including the extra coal burned at the boilers to power the drills on the coal (everything), electric furnaces use twice as much coal per smelted iron/copper plate, while producing only ~38.93% as much pollution per plate. (The inverse is, steel furnace produces 2.5690x as much pollution per plate. Also half as much coal & pollution per plate as stone furnaces.) Since coal is plentiful, I don't think using twice as much is an issue. And you can put modules in the electric smelters, and even in the drills, which pushes coal use and pollution even lower. But of course, electric smelters are much more expensive up front than steel, both individually and also because you need more steam engines. I like the reduced pollution output, because it means that evolution factor is lower by the time I start harvesting alien artifacts. I also scout at the beginning so that the worms are easy no matter how high the factor gets, though...

[@Xterminator]

Yup, definitely don't need them the whole way, but I prefer to do it that way just so it all looks the same. Really like your math, and it's pretty much what I would have guessed. I would also agree with you that less pollution is probably better, and the extra coal is not that big of a deal. That's why I prefer to upgrade to Electric Furnaces as soon as I can make them.

[@JackFruh]

Super Helpful!

[@Xterminator]

Glad to hear it helped!

[@HrafnNordhri]

How is your belt being magically supplied with ore and magically having the iron plate gathered at the other end?

[@Xterminator]

Raven North Using the cheat mode mod.

[@stillprophet7529]

please tell me im not the only one who saw the ore in the electric furnace bluebelt setup moving backwards

[@Xterminator]

Oh, you mean at the beginning of the belt by that wooden chest? It does look like it's moving backwards, but actually isn't. Just a weird visual thing.

[@gilian2587]

Where is your ore source!? -- You answered that question. Modded game. That's fine. Thank you.

[@theblackdragon7321]

Do you have a video on Smelter to miner ratios? How many miners do you need to satisfy 1 stone/steel/eletric furnace? Thanks!

[@Xterminator]

JJCM04 Unfortunately not. Typically you don't really need to ratio those out though.

[@luckyspec2274]

I'm confused as to why you have coal on the electric furnace belt

[@Larry-qz2fw]

Can you list the ratios in the description. So that it is easier to find it?

[@Xterminator]

Sure, I'll add them. Although the linked google sheets page has the ratios listed out nicely.

[@Larry-qz2fw]

There is a google sheet in the list?! I must be blind and missed that completely Edit: That sheet is very comprehensive. Great work

[@Xterminator]

Larry Shih Yeah it's hidden in there. :p Just a quick note, I didn't make the sheet, someone else did, but it is very comprehensive nonetheless.

[@TheFoxfiend]

I see that yes you get a full compressed belt out, but the ore only barely gets to the end of the line. With electric furnaces you don't need coal so you can dual side the input, does doing so do anything for you?

[@Xterminator]

I meant to take the coal off the Electric Furnace line, so you would definitely have a full belt of iron/copper/stone down each side. That wouldn't really make that much of a difference though. Because the output belt is already fully compressed even with the ore barely getting to the end. So having a full belt of ore getting to the end wouldn't do much aside form backing up the line. :)

[@TheFoxfiend]

another question, if you were to have full compressed input without coal, could you have a full compressed output of the next level up?

[@Xterminator]

***** Well without coal how would the the stone/steel furnaces run? :P But to answer the question, no I don't believe so. I think the belt still would not have enough throughput. It could be worth testing though!

[@jkchannel3149]

lol, i spend 1/4 of my time playing this game on thinking "this is just an extra belt"

[@jakobmertens6426]

Just so you guys know, inserters can fully compress a belt.

[@doougle]

I notice that there's room for a beacon between the electric furnaces when you use the underground belt for output..

[@Xterminator]

Yup. Although that would throw off the ratio, so make sure to recalculate for that change. :)

[@Ellsmells]

What is the belt at the end that makes all the iron disappear?

[@wcr1982]

For steel, because it takes 5x plate to make 1x steel, wouldn't you need 5x the belts of one colour to fill 1x of the same colour of steel?

[@Xterminator]

Well it depends I guess. In terms of smelting time and items required, it is a 1:1 ratio of Iron to Steel so that's why that Steel design works. You just need a huge amount of it to actually fill a belt of any color.

[@yasser83]

thanks man any new way to compress the belt items in .16 ?

[@scheidt5766]

Since eletric furnacess dont need coal, i can use the 2 sides of the belt for ore, does that mean i can doble the number of eletric, if i dont put coal?

[@Xterminator]

Kono Dio Da Not really unfortunately because you will still be limited by the throughput of the output belt the plate goes on.

[@sweetcrosby]

1:14 would end up having to make 2 sets and putting them together :p

[@TednTin]

Why do you have coal in electric smelting? with full(30/sec) iron ore of red belt you need 48 electric smelters in a straight line

[@IceExtremeGamers]

Hey, I have a question, how many furnaces are needed to deplete each one of the type of belts, I am planning on doing a robot-belt hybrid setup for funaces, but i can't get the math right in my mind.

[@Xterminator]

Good question! Well, without using modules or beacons, it should be the same number that are required to fill one of the belts. If you are using modules/beacons it can get a more complicated. You basically need to calculate for whatever your bottleneck will be, which in this case would be you input belt. So it actually is fairly easy for that because you just need to take the smelting time of your item, so for iron/copper, 3.5 seconds and divide that by the speed of your furnace (crafting speed, not % speed) to get the actual time it takes to smelt the item. Then, multiply the amount of items the belt can carry (13.33/s for yellow, 26.66/s for red, and 40/s for blue) by the actual smelting speed you got and that is how many furnaces total the belt can support. Keep in mind that those speeds I listed are for the whole belt (both lanes), and whatever furnace amount you get using those numbers will be for the whole belt, not each side. Hope that helps! If not, let me know and I'll try to get the answer you want. :)

[@IceExtremeGamers]

So, for a system with express belts and electric furnances we would need about 70 furnances?

[@Xterminator]

If you are not using any modules or beacons, then yes that is correct.

[@IceExtremeGamers]

I think I got it, thanks! XD

[@vtkrey]

Yea it's all good and well getting these ratios right early on but in time come along all the late game contraptions which throw all these ratios off and trying to compress a hundred belts and the near infinite amounts of ore behind them becomes almost impossible, god this game is so good but it gives me brain tumours.

[@Xterminator]

vtkrey I know the feeling. haha In time you'll learn the ratios and builds for late game too.

[@Bad_Moon_Rising]

How many miners would it take to fully compress a yellow , red, or blue belt to supply those max smelting lines?

[@Xterminator]

I plan to do a video on that soon actually. But you can take a look at the google sheet linked in the description, one of the slides shows that info. :)

[@Bad_Moon_Rising]

ahh thanks

[@dannyschumaker]

blue inserters and stack inserters

[@EvilNecroid]

so this is still the same for the current version of the game?

[@evanschannel611]

Doesn't having a full belt of ore with no coal for electric double the ratio?

[@Xterminator]

Nope because it will still be limited by the output belt.

[@hitsuokinawamura]

Can you make one like this but with the mining setups???

[@Xterminator]

Sure, I'll add that to my ideas list for tutorials!

[@maximos7854]

Is this still the case for the new .15? or did they fix the compression?

[@Xterminator]

Maximos A This is all still same. They didn't change anything with compression as of yet.

[@spinba11]

I'm trying red belt and steel furnaces but there isn't enough iron ore in the input belt to compress the output belt, the layout is 99% the same as yours (Iv go the coal spawning on the correct side so there is no need for an underground belt) do you think Ive done something wrong

[@Xterminator]

Are you sure that you are getting a fully compressed side of the input belt of Iron. As you saw in the video it should definitely be enough to compress the output belt. Could you send a picture of what you have and I can see what might be wrong? :)

[@spinba11]

Xterminator I'm using the creativity mode mod (not sure if that's the right name) to spawn the iron ore, when I get chance I will swap to the spawn belt mod and I will update you

[@spinba11]

I've changed to the spawn belt mod and it's working fine, I had a closer look at the old setup and the belt was 99.9% compressed.

[@Xterminator]

spinba11 Awesome glad you got it worked out! :)

[@fjoa123]

Why input coal to electric furnaces tho

[@physogames3537]

How do you make infinite items in ur pocket like iron plates etc

[@Xterminator]

By having cheat mode enabled. :) Here is the command for it: /c game.player.cheat_mode = true

[@schulzman1176]

what if you use speed 3 modules in the electric furnaces

[@Xterminator]

It will change the ratio because the smelters are faster. Not sure what the exact ratio will be using speed modules.

[@BlueBunny53]

Is the stone furnace faster then the steel furnace?

[@vortexpie7888]

Addison Faber steel furnaces have a crafting speed of 2 while the stone furnace has a crafting speed of 1, so yes steel furnaces are faster

[@BlueBunny53]

VortexPie thank you! After I said it out loud I actually face palmed at how long it took for this concept to click in my mind... all understood thanks for these ratios!

[@abeloth6223]

A youtuber by the channel name of Kim Keith has literally taken this vid and posted it on his channel, claiming it as him.

[@warwickthekingmaker7281]

don´t use burner inserters for coal. I did it at first but they burn much more energy than if you would have used the coal to generate electricity and use the orange inserter.

[@Xterminator]

The Lich King Yes that is true, but the point of using burner inserters is so you can still have them work if your power goes out for some reason.

[@warwickthekingmaker7281]

ah, but if power goes the other inserters stop working anyway and no new iron can be inserted into the furnaces. Isn´t it a bit pointless that the coal supply still works then? I´m thinking about the steel setup here, your point applies to normal setups with stone or steel furnaces where a burner can insert both at the same time.

[@taliesine.8343]

still up to date?

[@0623kaboom]

btw belt compression no longer works in 16

[@mgutay]

are these still relevant in the current build

[@spinba11]

yes but the underground trick is no longer needed

[@cryionic]

Sure, I can increase volume. It doesn't seem quiet to me, but it couldn't hurt to turn it up so I'll do that on future videos. :)

[@zoelanier4908]

how many elctric miners do you need

[@tosty9456]

For Iron Copper and Coal you need 26 Drills for Yellow Belts, 32 for Red and 77 for Blue, since all three resources have a Mining Speed of 0.525 for Electric Drills

killertoast lp you will need 78 I guess because you will need a number dividable by 2 for both sides of the land.

[@tosty9456]

Nils Kahle Yeah if you want to make it even you can do it this way. But just for technical purpose 77 is minimum :)

[@tornado52745]

so what are the mods that you use

[@Xterminator]

Mr_Twister The only mods I used for this were Spawn Belt and Creative Mode.

[@mattwhit02]

Is this still useful in 2019 with .16?

[@Xterminator]

Yup, the ratios are still valid.

[@mattwhit02]

Xterminator thank you for the quick response! I've been watching everything as I have just gotten into factorio! I want to start off right to launch that rocket!

[@surr3ald3sign]

lol good vid man. just a thought tho why explain the math if ur giving us the exact numbers? it just seems kinda like only done to be extra sure we got it.....not to be rude either but im betting most ppl just skipped to find the numbers, new sub keep it up dude

[@surr3ald3sign]

also. when i forst saw the thumbnail i saw a guy with a huge boner. anyone else?

[@Xterminator]

Thanks. The reason I explain the math and not just give the numbers by themselves is so that if people want to, they can actually understand why it works the way it does and how I actually arived at those numbers instead of just blindly trusting what I say to be correct.

[@nilskahle5863]

Xterminator appreciate the math! here it may not have other use cases, but if you are doing other ratio calculations or similar things it can be very useful to know how he math works. for example calculating the need furnaces and chem plants for red circuits. then you will need the math. hope you do give the math in the other videos aswell. have not seen them (yet)

[@game1boy1007]

is this valid in 0.15 still ?

[@Xterminator]

Yup! :D

[@nasherstad1520]

The coal and iron on the same belt kills me your only smelting half a belt not a full one

[@Xterminator]

But you are smelting a whole belt because you're sending in a full belt of Ore and just splitting it down both sides. These output a full belt of plate in this format, so adding any more Ore to the input would be useless.

[@nasherstad1520]

@@Xterminator that is true but you can use a different design that does take up less room then the design you showed if you wanted two full belts. You may be correct so I just want to tell you how I do it to see your take on it. First you have a belt of coal going down the middle. Next you put two iron belts on the sides of it running parallel with the coal. Then you can add the furnaces with the math for how much smelters it takes to smelt a full belt for that color of belt and run it that long. Then in the middle of the furnaces you can you can rearrange the inserters with the Splitter belt things so you can pack the belt that way.

[@BlueBunny53]

Why you got coal going to the electric furnaces? I watch Trailer Park Boys 3 times while playing this game... I know those maf'ks don't need that shit :) thanks for the info!

[@BlueBunny53]

Never mind..... de click in mah brain happen.... I's understands......

[@Xterminator]

Because I'm a derp and forgot to remove it. :P

[@snugglyjeff214]

Level up your OCD. You chose 48 instead of 47 to make them even...but you COULD have done an even 50....mmmm look at that beautiful 0 on the end...its a multiple of 10....it's half of 100. A OCD person's wet dream

[@Xterminator]

Snuggly Jeff Yes, but it's also a complete waste of 2 furnaces.

[@snugglyjeff214]

Xterminator you need to make sacrifices! OR! Increase the demand through your entire factory using a process of intricate calculations so that everything not only balances with each other, but they also NEED those 2 furnaces.

[@Mystickneon]

Why run coal to electrics? Your end furnaces are suffering from lack of resources.

[@Xterminator]

I didn't mean to, didn't even notice I had. lol The end furnaces are getting resources, just barely. The output belt is fully compressed all the time though so it isn't really an issue.

[@dappergunman6660]

dont gap the whole belt for full compression, too expensive. the last one or two will do it.

[@Xterminator]

Dapper Gunman Yup very true. Some of it is personal preference. I'd rather spend the resources to have the whole thing look the same but that's just me.

[@randomguy7503]

I feel your OCD... Same here!

[@randomguy7503]

10:00 this belt let me right klick on the screen...

[@junjung2975]

hmmm yeah alright, ok compared to this my factory is just... work?

[@MrMoon-hy6pn]

This videos outdated you can compress belts completely now with inserters

[@Xterminator]

The primary information in the video, the smelting ratios is not outdated and still applies.

[@JohnSmith-lr6kf]

Another major flaw: you don't like 47?!

[@Xterminator]

Unfortunately not really. :p I prefer round even numbers myself.

[@alexbotsama7086]

it's a prime number tho :D

[@branthebrave]

Alex that makes it worse
