Rubber Liners

Rubber Mill Liners are chosen for most Primary, Secondary and Tertiary Ball Mills. And in many cases rubber components are best suited for specific areas in AG and SAG mills.

Rubber Mill Liners are extensively used in FGD mills at Power Plants all over the world.

Polycorp has supplied complete rubber linings in some of the largest ball mills in North America at 24 feet in diameter.

We have supplied Rubber Liners for more than 400 mills worldwide.

Polycorp lifters are made of tough abrasion resistant rubber with decades of proven field use, guaranteeing their ability to withstand the relentless pounding of mill action. They are available in a selection of profile designs and heights to give unexcelled performance under various grinding mill conditions.

Polycorp’s rubber liners are designed and arranged so that the lifter bars can be easily replaced without affecting the shell plates, which can outlast lifter bars by at least two to one. Our lifter bars are engineered to be compatible with most shell and end liner plate designs.

Our rubber lifter bars will utilize your current bolt hole spacing. This eliminates the need to drill new attachment holes. All components are moulded to meet your specific mill and operating conditions.
