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:
Oyu Tolgoi High Tension Bend Pulleys – Improved Performance
Oyu Tolgoi is a large copper mine that has both open-cut and underground operations and has been operating since 2013. The mine is jointly owned by the Mongolian government and Rio Tinto and is located in the South Gobi Desert. Once fully operational, the mine is expected to produce 450,000 tonnes of copper annually.
Vale’s Vargem Grande Iron Ore Conveyor Lagging Problem
Vale-operated Vargem Grande mine site is located in the state of Minas Gerais, Brazil and contains 2.53 billion tonnes of proven and probable iron ore reserves, making it the world’s fourth biggest iron ore mining operation. The Vargem Grande site comprises three open-pits: Tamandua, Capitao do Mato and Aboboras.
