In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rod mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for …
Ball mills are displaced, based on a lack of need, in single-stage AG/SAG plants. Ball-mill technology is well understood, as is classification, which is typically performed in hydrocyclones. However, in practice, secondary milling circuits are often operated at less than peak efficiency. With throughput in many cases worth more …
Ball Mills are manufactured from carbon steel, AR400 abrasion resistant steel, stainless steel, Alumina ceramic lined, polyurethane lined, and rubber lined depending on material compatibility and solids characteristics. Ball Mills have working capacities from 0.1 gallons to 1,500 gallons (0.013 to 200 cubic feet).
