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 (Photo#1). 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.
• Change out during a planned maintenance shut
• Emergency change out due to catastrophic pulley failure
