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.

Ceramic Lagging Tile Loss – Causes and Prevention
Ceramic lagging is chosen for pulleys where a long trouble free service life is required to ensure that the conveyor is operational when required and to avoid unplanned conveyor shutdowns. This is a critical for mining companies where conveyor down time costs run into thousands of dollars per minute. While ceramic lagging is considered expensive […]
The importance of good metal preparation to good lagging adhesion
Poor metal surface preparation Note uneven finish and the presence of machining marks – no evidence of grit blasting. The results of poor metal surface preparation – lagging debonds from the pulley shell – edge lifting and corrosion – corrosion of the pulley shell at the joints between lagging strips. Correct pulley shell surface preparation […]

PPC operates seven power stations that are fuelled by Lignite and a number of mines that supply the fuel for these mines. The PPC operations have conveyor systems […]
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.
How to Maximise Your Pulley Lagging Service Life: Hot Vulcanised vs Cold Vulcanised Application
Overview Mining technology is rapidly evolving to meet the challenges of extracting minerals in remote locations, often with extremes of weather and often from ore bodies located deep underground. To achieve production costs that are competitive and sustainable, a number of new technologies are being adopted by major mining companies. These include increasing use of […]
New Technology Extends Service Life of Non Drive Pulleys and Protects the Conveyor Belt
Mining is an industry where reliability is crucial and unplanned down time can result in millions of dollars lost over a single day. Pulleys are a critical part of the conveyor, and need to provide exceptional performance, ensuring that the material handling system is operational when required. Pulleys and lagging need to work together. There […]
