overflow ball mills and grinding ball mills. By using special alloy steel segments moulded into rubber, composite plates greatly reduce the liner breakage risk, present in the grinding process where balls of over 100mm are used. In addition, composite linings are up to 3550% lighter than their metal equivalents. This translates into an
