The batch ball mill required periodic changing of the reducer oil after an initial period of 500 hours of operation or one month, whichever occurs first. A petroleumbased gear oil with or without EP additives should be used. Thereafter, change the reducer gear oil after 2500 hours of operation or six months, whichever occurs first.

How the Batch Process Works. The operation of a batch size production mill is simple and effective. The material to be ground and the grinding media are placed in a stationary, jacketed tank. This media is spheres 3/32" to 3/8" diameter. Commonly used types are carbon steel, stainless steel, chrome steel, tungsten carbide, ceramic, or zirconium ...
Ball mills are used to obtain a product size below 150 microns. With the rotation of the mill, collision and attrition forces grind down the material in the mill chamber. The balls act as the grinding media, where contact points are created with each other and the material is either crushed or ground.

Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art it''s just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are nonlinear or have paradoxical effects on the end results.
