Ball Mills
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob 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 subsequent treatment.

How to use a tooling ball?
A tooling ball is simply a tool that we use to precisely locate a point. 2 points create a line, 3 points can be used to create a plane. Other features on a part, in combination with a tooling ball can be used to extrapolate a plane from a linear feature. To do this on paper or manually takes good geospatial abilities.

The opening is closed and the mill is rotated for several hours. It is then stopped and the product is discharged. 5. The ball mill is used for grinding materials such as coal,pigments,and fedspar for pottery. Grinding can be carried out in either wet or dry but the former is carried out at low speeds. The advantages of wet grinding are less
