Hi,

We have a vibrating grizzly feeder from Haver, which belt jump off from the pulley during operation.

Although the belt-pulley assembly is vertical to excitation line, the belts escape from the pulley frequently even during operation or start-stop.

Meanwhile they have used cogged belt instead of simple V-belt, is it ok?

This is strange for me, why they have not used crank shaft in this system.

Dimension: 1466 x 7200 mm

stroke: 12mm (amplitude=6mm)

frequency: 730 rpm

Would you please inform me what is you suggestion to solve this problem.
