Updated Kevlar® Belts in Mining Brochure

The top and bottom covers of conveyor belts are designed to meet different requirements. The top cover must have high damage resistance (cut, abrasion, wear and puncture), while the bottom cover must be highly engineered to have low hysteresis properties, providing low indentation rolling resistance, so the belt consumes less power under operation.

How Do You Extend The Life Of Your Wire Mesh Conveyor Belt?

Posted June 20, 2014 by Joel Black. ... on the underside of your conveyor belt rub or come into any contact with the support strips this can lead to extra wear and fatigue failure. ... This will lead to premature wear of the conveyor belts.

Reliability - ConveyorTechnologies Ltd

This fatigue failure will normally occur in the splice since this is the belts weakest point. Insufficient initial belt tension can induce belt elongation which may cause slippage and wear. Once this elongation exceeds the conveyors tension range, a serviceable belt may have to be discarded.
