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 …
Step2 Rotation of the Cylinder: Once the materials have been fed into the ball mill, the cylindrical container begins to revolve on a horizontal axis. This rotation is done by a motor and drive system which is seen at the far end of the mill in the picture. The rotational speed can be adjusted to ensure that the grinding media and the material are …
