Cement ball mill.Cement plant, clinker grinding unit capacity 21-155 th motor power 800-3550 kw fineness 33003800 cmg overview.The ball mill for clinker is an efficient tool for fine powder grinding.It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical.
Cement manufacturing - brief description of a cement mill.Cement clinker is usually ground using a 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 ball mill is a tumbling mill that uses steel balls as the grinding media.The length of the cylindrical shell is usually 11.5 times the shell diameter figure 8.The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
The grinding process remains a challenging issue, due to the elevated degree of uncertainties, process non-linearity and frequent change of the set points and the respective model parameters during operation.For productivity and quality reasons, grinding is mostly performed in closed circuits the ball cement mill cm is fed with raw materials.
Cement grinding is a crucial stage of the ow sheet, where both cement quality and process e ciency are decided.Achieving the required neness with maximum e ciency is down to the design of the ball mill and how well it runs.An ine cient system can push your energy bill right up, making it a lot more expensive to produce.
The basic parameters used in ball mill design power calculations, rod mill or any tumbling mill sizing are material to be ground, characteristics, bond work index, bulk density, specific density, desired mill tonnage capacity dtph, operating solids or pulp density, feed size as f80 and maximum chunk size, product size as p80 and maximum and finally the type of circuit openclosed.
