  • Autogenous Grinding Information

    Autogenous grinding has two advantages, (1) it reduces metal wear and (2) eliminates secondary and tertiary crushing stages. Thus it offers a savings in capital and operating costs. Autogenous mills are available for both wet and dry grinding. The diameter of autogenous mills is Autogenous Grinding Article about Autogenous Grinding by,In comparison to grinding with steel rods or balls, autogenous grinding has the following advantages: (1) the crushing of the ore before milling is simplified and made less expensive, (2) the expenditure of steel rods or balls is eliminated or reduced, and (3) the technological efficiency for the concentration of some ores is improved as a result of less overgrinding of a valuable mineral.
