grinding aids coat the surface of nascent cement clinker which enables the elimination of “coating” of finer materials on the surface of grinding media and grinding mill walls. grinding aid can be used to either increase the surface area of cement at the given production rate or it can increase the production rate of cement with the same surface area.,clinker grinding in cement production,in cement production entire crushing and grinding process consumes about 85% of the electricity. at the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding. according to some hypotheses, only a thousandth blow of the ball is spent on grinding the material. thus, cement plants are among the most demanding for grinding balls quality customers of

Cement grinding Vertical roller mills versus ball mills

Cement Grinding Vertical Roller Mills Versus Ball Mills

as less grinding energy is used in producing a cement of a required fineness in an ok mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. this means that a lower degree of dehydration of the gypsum must be anticipated. this may not be a problem if the gypsum is sufficiently,china cement grinding ball mill use grinding media ball,cement grinding cylpeb of required sizes 45-65 hrc, 1-23 % cr. content. the grinding media grinding ball is produced by full-auto casting lines, certified under international quality standards. we guarantee our cement grinding ball has low breakage rate, lower wear of consumption, and fast delivery terms.
