AG Autogenous Grinding Mineral Processing

2020-5-18  Liner wear in the test mill was higher than in the rod mill—ball mill circuit but total steel consumed was considerably less. Estimated saving for inter-mediate autogenous grinding is 65 to 70% of the cost of rod and ball consumption. The test mill required the constant attention of an operator.
