The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different

Ball mill that works on the principle of impact is an efficient technique of size reduction through grinding. The size reduction is an important factor for many industrial applications as this process is carried out to increase the surface area, to intimate mixing and to improve dissolution rate, solubility, binding strength and dispersion properties. . Therefore it is important to maintain

Factors affecting the quality of the final product undergoing size reduction process can be classified as those belonging to the material and those that are due to the grinding machine.

Grinding Mill speed is one of the factors affecting the character of the cascading charge. The ball mill product is further ground in a jar mill until 92 percent passes 200 mesh. these mills are of lighter construction and require only about one-third the horsepower of a ball mill of equal size.

Several types of ball mill exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 litres for planetary ball mill, mixer mill or vibration ball mill to several 100 litres for horizontal rolling ball mills.

The Main Factors Affecting the Particle Size of Ball Milling. It is not easy to get nano size powder by planetary ball mill, normally effect of wet grinding is better than dry grinding. The main factors affecting the particle size of ball milling. 1. Material of the milling tools (milling jars and balls).

Factors affecting size reduction Softening temperature: During size reduction process sometimes heat is generated which may cause some substances to soften, and the temperature at which this occurs can be important. Waxy substances, such as stearic acid, or drugs containing oils or fats are examples that may be affected. Some methods can be used to overcome this like cooling the mill, either
