Pulley Lagging thickness

Posted in: , on 21. Aug. 2020 - 15:50

Good Day to all,

Is there a method to calculate the optimum thickness of lagging on a conveyor pulley? In other words, what are the factors to be considered while deciding the thickness of lagging on a pulley?

Regards,

Pulley Lagging Thickness

Dear Harithejo,

The explanations of Elastotec is surely very useful.

I would like to take this opportunity to point out an alternative that we are currently trying out on our dynamic test bench.

We decided to make a special coating of a small pulley. After grindig we coated directly our epoxy glue Multi-EP, and then overcoat it with grit-blasting material, to ensure best grip and abrasion resistance. The special adhesive properties of Multi-EP also allows minimal preparation of the contact surfaces, even only cleaning if sandblasting or grinding is not possible. It can be done directly on the used pulley without the need to dismantle it from the conveyor. Sharp-edge melting chamber slag and silicon carbide or corundum or ceramic beads with grit size 0.1-2 mm seems to provide the right grip without damaging the belt.

I should appreciate to receive some comments or feed-back.

Best regards
