Screw Conveyor and Bucket Elevator Working Principle 
Screw Conveyor Working Principle 
The power transfers to the screw shaft by the belt sheave. The materials 
flow into the delivery pipe through the feeder, and then the materials are  
propelled to the upper discharge hole. And the materials can fall into the  
roasting machine.

The conveying speed can be adjusted.
