Description

Technical Field

It utilizes the frictional torque between the hopper belt and the head pulley drive shaft to drive the hopper via a chain or belt, thereby achieving vertical or inclined material conveying. This device is suitable for conveying powdered, granular, and small, abrasive or non-abrasive materials such as mineral powder, coal, and limestone.

[0003] After checking the publication number: CN220448772U, a bucket elevator for mineral powder processing is disclosed.
