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

Factors Affect Ball Mill Efficiency

Then the damage of ball mill, scale board and grinding media will be less, so will the energy consumption. On the contrary, if the grindability is high, the damage and energy consumption of ball mill will be larger. So the properties of raw material will directly affect the production rate and play most important role in the grinding process.
