Ball Mill - Wikipedia

a ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

ball mill. the term “ball mill” is usually applied to a mill in which the grinding media are bodies of spherical form (“balls”) and in which the length of the mill is of the same order as the diameter of the mill body; in rough figures the length is, say, one to three times the diameter of the mill.

Factors Affecting Ball Mill Grinding Efficiency

Factors Affecting Ball Mill Grinding Efficiency

mechanisms of grinding in a ball mill can be broadly grouped as either impact or attrition with at least two forms of breakage attributable to each type. impact breakage may occur as a result of a particle being smashed between balls or between a ball and the mill lining, but is also generally defined to include slow compression fracturing, or crushing of particles between grinding media.



usually continuous mills are used when the production rate is required to be high. applications: specially designed for:cement, iron ore, copper ore, alumina, cement, calcium carbonate, bauxite, calcium carbide, calcium oxide, wet grinding, ceramic, refractory, slurry, coconut shell, carbon industries etc.
