Jenike Johanson Screw Feeder Models

Demonstration of different screw feeder geometry to overcome a funnel flow pattern in a hopper without changing the hopper design.

Perfect video for educational purposes! no doubts on why this design needs to be considered.

Hi. The most beautiful expression I have ever seen. Thank you.

[@durgeshkumaryadav1755]

it seems that screw shaft dia. and pitch is varying from start to end , shaft is larger to small and pitch is lower to higher, is there any fundamental equation or note to this ratio related to discharge, please share in comment or in my mail.

this is easy. you can calculate flow like (big area*flight lenght)-(small area*flight lenght) = x m3 for 1 turn in this video. you can say for exm. first 1 m carries 1m3 in 1 turn, secon 1 m carries 1.5 m3 in 1 turn and others like...2 or ....

You should have put in a few horizontal layers of colored material between the ordinary sand when filling the hopper. That would have shown mass and pipe flow even better.

Gorgeous ! thank you for this this is life saver.

Does it will give constant quantity dispense every time if we maintain constant revolution of shaft

[@arunrameshkumar9468]

What material are you using?

[@verghesepaul1545]

Well explained

Hi, it looks like a render, am I right?

[@HaiHai68]

very good...
