challenge in grinding cement in vertical mill

Italy Abstract Due to the stringent requirement of energy saving mainly used in the grinding production of cement clinker. Our company absorbs the latest grinding technology from Europe and combines with the market demand of grinding industry to develop a new and improved vertical cement mill.These differences between cement grinding and grinding of raw materials made it a serious challenge to obtain a good performance of a vertical roller mill in cement grinding. Today
