What is a Mill Relining Machine?
Mill liners are designed to be sacrificial linings to protect grinding mill shells and to enhance the movement of the charge for optimum throughput and grinding performance. A Mill Relining Machine is a purpose designed machine used to remove and place liners in grinding mills. Typically, RME's Mill Relining Machines find application in the larger AG, SAG, Ball and Rod mills throughout the hard rock mining regions of the world. Mill Relining Machines as they are today were invented by John Russell of Russell Mineral Equipment to make the process of replacing mill liners faster, safer and more reliable.
Prior to the introduction of the modern Mill Relining Machine, mill reline personnel resorted to a variety of dangerous and largely inefficient methods for removing and inserting liners, including truck mounted cranes, overhead cranes, chains and pulleys, and brute strength. For these reasons grinding mills were much smaller because mill shell liners and consequently mill size was limited by the weights and sizes of the liners that could be physically manoeuvred. Furthermore the grinding process was less efficient due to the fact that liner profiles were designed for liner life (not productivity) due to the long time that it took to complete each liner change.
Today, liners up to 7250kg are able to be manoeuvred precisely into place with the 7 axis or 8 axis movement of a RUSSELL Mill Relining Machine. RME has Mill Relining Machines installed at sites which operate what are currently the world's largest grinding mills (40' diameter mills). Without RME's constant Mill Relining Systems innovation such massive mills would not be possible because there would be no effective way to replace the liners in them.
RME is currently working closely with key partners in the grinding mill industry to develop mill relining solutions for the next generation of AG/SAG mills, which are expected to have diameters up to 44' and liner weights up to 10 tonnes.
