Construction of ball mill. It consists of a hollow cylinder that is mounted on a metallic frame in such a way, that it can be rotated on its longitudinal axis. The cylinder contains balls that occupy 3050% of the mill volume The weight of the balls is kept constant. The ball size depends on the size of the feed and the diameter of the mill.

The length of the mill is approximately equal to its diameter. Principle of Ball Mill : Ball Mill Diagram. • The balls occupy about 30 to 50 percent of the volume of the mill. The diameter of ball used is/lies in between 12 mm and 125 mm. The optimum diameter is approximately proportional to the square root of the size of the feed.

Hammer Mill Working Principle. The hammermill, fundamentally, is a simple mechanism. The "orthodox" machine comprises a boxlike frame, or housing, a centrally disposed, horizontalshaft rotating element (rotor) on which the hammers are mounted, and usually a set of circumferentially arranged grates in the lower part of the housing.

Function Principle. The grinding jar is arranged eccentrically on the sun wheel of the planetary ball mill. The direction of movement of the sun wheel is opposite to that of the grinding jars in the ratio 1:2. The grinding balls in the grinding jars are subjected to superimposed rotational movements, the socalled Coriolis forces.

The tumbling mill principle is based on the impact and attrition of the grinding media against the materials to be ground. As the cylinder rotates, the grinding media falls, collides, and crushes the materials inside the cylinder. The impact of the grinding media generates heat, which can affect the quality of the final product.
