Hot Vulcanised lagging application involves the chemical cross-linking of five reactive layers during the autoclave curing process. To achieve the
In November 2017 a major iron ore port facility in the Pilbara decided to replace the ceramic lagging on a
Spare pulleys are held so that in the event that an operational pulley requires replacement this can be done quickly
Catastrophic lagging failure due to debonding occurred within two weeks of installation and operation of the pulley, resulting in a
Lagging can be of good quality and application can be correct, but lagging can still fail and does. Everything seems right but the lagging still doesn’t perform to expectations. So why does this happen? It’s because the lagging selection is not right for the application.
Elastotec extreme diamond rubber lagging is designed for drive and non drive pulleys that require extended service life.
At Elastotec, we engineer lagging solutions that keep conveyors running. Here are some causes of lagging failure.
Elastotec Direct Bond Ceramic Lagging - application system designed to improve adhesion consistency, reduce lead times, reduce glue wastage and labour time.
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.
Simple system that provides an easy to recognize visual indicator that the abrasion resistant diamond lagging layer has worn through and should be scheduled for replacement. Provides a margin of safety by identifying wear before contact / damage to the pulley shell occurs.

Thickness variation (all strips/pulley) +/-0.5mm
Ceramic lagging with thickness > 15mm only recommended for pulleys with diameters over 600mm.
If you work in the mining industry, involved in conveyor maintenance, pulley manufacturing, conveyor design and conveyor maintenance, then, we would like to work with you to bring engineered pulley lagging solutions to the industry.
