Ball Mill: Operating principles, components, Uses,

Ball mills grind material by impact and attrition. The degree of milling in a ball mill is influenced by; a. Residence time of the material in the mill chamber. b. The size, density, and number of the balls. c. The nature of the balls (hardness of the grinding material) d. Feed rate and feed level in the vessel. e. Rotation speed of the cylinder. Several types of ball mills exist. They differ,Ball mill, Ball grinding mill - All industrial,,A ball mill crushes solids into a fine powder within a rotating drum, using balls as the grinding medium. Applications.

The operating principle of the ball mill

The operating principle of the ball mill

Energy consumption for ball mills is a function of many factors: the physical properties of the ground material — its specific gravity and hardness; the degree of drum filling by grinding balls; the number of drum rotations, etc. Ball mills have low efficiency — no more than 15%. Energy is mainly consumed on the wear of grinding balls and mill housing, friction; heating the material etc,Sample preparation of plastics and in the chemical industry,The Emax is an entirely new type of ball mill which was specifically designed by RETSCH for high energy milling.
