A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%. Ball mills are.

The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. . Width calculation to determine this value. The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width. Mill Actual RPM:.

The grinding plant at a cement factory is used to reduce the particle size distribution of various materials such as raw meal, fuel or clinker to set parameters. In a sense, a grinding plant uses energy (through milling) to create fineness and it is the production personnel's aim to optimize the fineness with the production rate.
