WEAR INDICATOR RUBBER LAGGING

DESCRIPTION

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.

Simple system that provides an easy to recognise 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.

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.

FEATURES AND BENEFITS

Rubber backing developed in conjunction with ARDL (Akron Rubber Development Laboratory) to retain flexibility at low temperature (-50C).
High performance abrasion resistant synthetic elastomer.
Coloured wear indicator layer below abrasion resistant layer.
Proven bonding system between abrasion resistant synthetic elastomer and CN backing coloured rubber.
Coloured wear indicator (Blue for SBR and Red for FRAS).
High quality rubber formulations designed for good bonding, resistance to degradation by out door exposure, and good abrasion resistance.
To be applied though hot vulcanising method to eliminate the chance of lagging debonding from pulley shell and separation on joins.
Can be supplied in a range of thicknesses (15, 20 and 25 mm).
Suitable for long term service at temperatures from -40C to +70C.
