A cement mill is key equipment for re-crushing the materials after they are primarily crushed. It is widely used in the dry type and wet type powder grinding of all kinds of ores and other grindable materials in cement, silicate product, new type building material, refractory, fertilizer, ferrous metal, and non-ferrous metal beneficiation and glass and ceramic production industry.

Get PriceCement Mill. Cement clinker is usually ground using a cement ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. Grinding systems are either 'open circuit' or 'closed ...

Get PriceCalculation of the power draw of dry -compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.
