Analysis the Abrasion Situation of Ball Mill

A grinding mill is a unit operation designed to break solid materials into smaller pieces. There are many types of grinding mill, such as ball mill, Raymond mill, MTM trapezium grinding machine, high pressure suspension grinding mill and so on. As an ideal grinding mill for secondary crushing, ball mill is an efficient pulverizer machine for fine powder grinding. Ball Mill is widely used in many fields. This durable ball mill can grind many kinds of mine and other materials, such as the cement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc.

The abrasion of the steel ball of ball mill is an irreversible process of “physics to machine” and “physics to chemical” that happens on the surface of the solids. The abrasion of the steel ball is mainly divided into mechanical abrasion and corrosive wear these two types, and the former is caused by impact, grinding Diesel engine hammer crusher, friction and fatigue, and the latter is caused by the effects of ion and chemical agents in the rock slurry.

The abrasion speed influenced by impacting and grinding is mainly determined by the impacting energy, which are the weight of the steel ball and the size of the grinding machine. In the moment of impacting touch, the touching point will produce highly concentrated stress, which will cause the plastic deformation of the surface of the steel ball, for this reason small jaw crusher, the steel ball surface will form cracks with different shape and depth. In the rock grinding process...
