Mill Optimization: We offer a Mill Optimization Service whereby one of our engineers will visit a cement site to carry out a full internal mill inspection. From this we offer advice on mill performance, condition of grinding internals and grinding media charge.
For instance, the rotational speed of the mill, and hence the relationship between gravity and the centrifugal forces acting on the rock particles and the grinding media, has a significant effect. The charge within a mill being run at 90% of its critical rotational speed will behave differently from that in one running at 75%, in which gravity ...
