Scrap Metal Hammer Mill Build, Parts, Design For Shredding & Crushing

Our largest 34"x24" scrap metal hammer mill for crushing, shredding and liberation of valuable metals. In this video Jason walks through the hammer mill operation, parts, and maintenance. Showing the inside of the hammer mill, screens, armor, bearings, shaft etc. This large mill is capable of shredding up to a 20 lb piece of scrap metal or other material that needs to be reduced in size for separation or size reduction.

Great Design - I like the way you engineer your products!

[@mbmmllc]

Great! Thanks!

[@brandoncady7043]

As someone who works on one of these designed to chew up cars and vans, its interesting seeing it on a small scale.

[@TheK9collins]

What size motor you running ?

[@goober239]

Hey im curious but do you have a hammer mill that is small that is light weight and will only run wood and wood products? Im thinking about using one to mount to my pickup which feeds into a wood gasifier.

[@buensomeritano1755]

consider a system that takes ALL the material down to 100 or 200mesh- , so the particles are all the same size. Even if it requires switching out mill screens and running several times. Then, put more grade dividers on the table to get a better grading effect, and run each grade on the table at least twice to get the highest true grade possible. Classifying the material before running across the table will keep the particles the same size and will keep trash out of the high grade material. Running each grade a second time, on it's own, on the table, should give you finer gravity separation of the different metals. Any magnetic separation should be done AFTER the full size reduction, but should not be necessary if the grades are classified and individually run a second or third time each. The ferrous should separate from the non-ferrous due to difference in Specific Gravity. Table angle and flow may have to be adjusted when you get down to clean metals to get sufficient separation.

[@mbmmllc]

Thank you for the tip! We'll definitely take a look into that!

[@ricardomora692]

How many tons can be crushed until the manganese steel hammers wear out?

[@josepacheco9479]

I work at a scrap yard and they have a shredder like this but 20X bigger idk the name of it but I weld bolts and pad eyes on the half moons to be lifted up with a crane

[@thunderbird19603]

I see your design doesn't use anvils. Does this wear your screens quicker?

[@Rokonroller]

Great explanation

[@mbmmllc]

Glad you liked it

[@mikeknutson415]

Very good detailed informative video... you guys keep making your machines beefier and beefier... one question though why do you turn the big 6 inch shaft down to smaller ends.... 6 inch bearings with a 6 inch shaft sounds more stronger... just curious

[@mbmmllc]

Thanks Mike. The 6" shaft gives the strength, and turning down the ends doesn't compromise strength, but the bearings are A LOT cheaper.

[@Jimo225]

is there some sort of anvil in it that the hammer hits the object against to hammer it? or does it just hammer the stuff agains't the screen

[@estebandelaossa]

great videos!! I am wondering if the AR 400 steel is only for the inside of the upper lid?!

[@johnkennedy6621]

Can it be use to crack Palm kernel nut?

[@christiancrowe8996]

Do you guys sell these machines? Looking for a versatile machine to process scrap. Wire harness, al/cu rads, aluminum. Not sure what I need

[@mbmmllc]

Email us at [e-mail] for more info on these machines. Thanks

[@melvinthomas940]

how would this work with lime stone

[@shredderegypt3394]

Weight of the hammer and do you have video assembly it together

[@1Cypress1100]

no hard facing on the rotors? is the rotors made of S355JR or hardox400,

[@metalworksmachineshop]

They would advise doing it but most all companies dont , because they want your business on replacement parts. I use a high chrome rod on our machine. Our hammers are also AR500 3" wide. Our screen is also AR400. and the feed box is made of .500 thick AR 400with 1" liners and a mag, anvil.

[@mbmmllc]

AR400, the rotors last a really long time in scrap operations. Thanks for the question

[@shredderegypt3394]

How do you do the screen or the filter? How can you made this curve

[@shredderegypt3394]

Explain how is the rotor assembled.

[@melvinthomas940]

how can i vet one to buy

[@Balekami_]

Great machine 👍

[@wujourney865]

Great machine. If change the hammer head to carbide brazed, the performance can be much better!

[@metalworksmachineshop]

Wish you guys were closer , you need to come look at ours. Needs to be more efficient, and not destroy it self so quick. Also its 3x bigger that this one in the video. 150hp 24" rotor, 3" wide hammers about 30lbs each.

[@mbmmllc]

Thank you for your comment and for watching our videos!

[@williamhoward8319]

oil bath bearings seme to work better than grease they run cooler

[@ursamines7643]

What is the Rockwell hardness that you use for the hammers, screens, and walls?

[@metalworksmachineshop]

The hammers are self hardening. They will go to 600R + is a few days. The AR400 is about the same. The bad thing about the hammers is the shaft hole will stretch over time and ware out the bar and cam or brake the bar if its 4140 , 4150 bar should be used for very long life.
