How to Reduce Steel Consumption in Grinding Mills

The ripple wave liner was "patch" tested in a large operating ball mill in Arizona, and the next step is to test the permanent-wave type of Ripple-wave liner in suitable ball and rod mills. In the long range development of these liners, several alloy composites should be evaluated for cast bars, and the design should be optimized.
