Elastotec Extreme Rubber Lagging
Elastotec extreme diamond rubber lagging is designed for drive and non drive pulleys that require extended service life.
Elastotec adhesion testing
At Elastotec, we engineer lagging solutions that keep conveyors running. Here are some causes of lagging failure.
Elastotec Direct Bond Ceramic Lagging
Elastotec Direct Bond Ceramic Lagging – application system designed to improve adhesion consistency, reduce lead times, reduce glue wastage and labour time.
Hot Vulcanised Lagging Application
Hot Vulcanised lagging application involves the chemical cross-linking of five reactive layers during the autoclave curing process. To achieve the desired 100% rubber tear adhesion all five layers must crosslink at the same time. Occasionally conditions can be created in the autoclave that prevent this happening, and result in non-uniform adhesion around the pulley circumference. This bulletin explains how these conditions occur and what needs to be done to eliminate this problem.
Iron Ore Port Facility High Tension Bend Pulley – Elastotec Polyurethane Lagging
In November 2017 a major iron ore port facility in the Pilbara decided to replace the ceramic lagging on a high tension bend pulley – the ceramic lagging had suffered physical damage on one edge that had exposed the pulley shell. With a capacity of around 180 million tonnes/annum of iron ore the port operates 24/7 year round and so reliability of the conveyor system is critical to achieving the maximum ore through put.
Spare Pulleys – Hot Vulcanised vs Cold Bonded Lagging
Spare pulleys are held so that in the event that an operational pulley requires replacement this can be done quickly and efficiently at the timing dictated by the mine maintenance personnel. The reason for changing a pulley broadly falls into two categories:
Elastotec Expands Lagging Operations
Our dedicated teams in Australia and Vietnam working really hard to understand lagging performance, and to engineer solutions that provide the longest possible lagging service life under all conditions.

Consequences of Catastrophic Failure with Cold Bonded Lagging for New Mining Projects
Catastrophic lagging failure due to debonding occurred within two weeks of installation and operation of the pulley, resulting in a shutdown of production, and necessitated a replacement of the pulley. Within only two weeks of service, this ceramic lagging was already experiencing loss of the ceramic tiles.
