AG Mill Liners

1. Hardness difference from surface to center is less than HRC2.

2. The series are designed for high abrasion performance.

3. HRC33-43,

4. AK≥60J.

5.The bolt holes are clean,smooth.

Our main product series are ball mill liners, wear parts for crushers and grinding media. Boltless Ball Mill Liners decrease maintenance of liners and save the cost of bolts. What’s more, our boltless-liner design can exert the maximum quenching hardness of metal material while the bolted-liner design has to scarify the quenching hardness to get better toughness because each bolt hole is a source of thousands of crackings.
