Wear Indicator Rubber Lagging is popular having a visual indication on when the lagging needs to be scheduled for replacement.
Elastotec Wear Indicator Rubber Lagging has been developed to provide mining companies with a long life lagging that will provide a visual indication when the abrasion resistant lagging has been worn away and the lagging should be scheduled for replacement. The coloured wear indicator layer is designed to indicate when the lagging replacement is required and to also provide protection for the pulley shell while lagging replacement is scheduled.
The primary aim is to prevent wear of the pulley shell that may lead to the need for an expensive replacement of the whole pulley. Many mines spend considerable time measuring the thickness of the lagging on the pulleys once in service to keep track of replacement requirements. This normally involves operators using ultrasound techniques on the pulley surface during shutdowns to record the remaining thickness of the lagging. A visual alarm while conveyor is running reduces likelihood of pulley shell wear as well as maintenance hours for lagging control.
