ball mill introduction. ball mill an example of grinder is an efficient tool for size reduction of solid through grinding for many applications e.g. in chemical industry.grinding means sub dividing the solids to a finer product than crushing. principle ball mill works on the principle of impact that is the size reduction of the solids is done by the impact. construction a ball mill consists of

planetary ball mills preliminary size reduction assisting for the coarse and prelimi-nary size reduction of hard, brittle or even tough materials, retsch jaw crushers are the instruments of choice. In con-trast, bulky, soft, fibrous or elastic materials are best pre-pared in retsch cutting mills. fine size reduction with impact

grinding medium are the metalic balls are usually made of iron, manganes or steel and occupy between and per cent of the volume of the mill. the diameter of ball used will vary between mm and 125 mm the ball mill is used for the grinding of a wide range of materials and it copes with feed up to about mm in size.

planetary ball mills are used wherever the highest degree of fineness is required.apart from the classical mixing and size reduction processes, the mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes.the extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and

ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. the variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications.
