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.

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.

Curragh coal mine – improved service life of conveyor pulleys

The Curragh Coal Mine is an open cut coal mine located near Blackwater in Central Queensland, Australia. The mine supplies high quality, low ash coking coal and has reserves of approximately 90 million tonnes which is amongst the largest in the world. Coal from Curragh is shipped via the Blackwater rail system to the Port of Gladstone for export. Curragh Coal mine is owned by the Coronado Coal Group a US based company.

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.

White FDA-approved Ceramic Lagging – bulk sugar ship-loading conveyor

Sugar Australia operates a specialised food-grade bulk refined sugar vessel, MV “Pioneer”. Elastotec developed a white ceramic lagging made from FDA materials approved by the U.S. Food and Drug Administration (FDA) for handling sugar on a ship-loading conveyor drive pulley.
