LM Vertical Roller Mill. LM Vertical Grinding Mill integrates five functions of crushing, grinding, powder selection, drying and material conveying. It is characterized by centralized technological process, small occupational area, low investment, high efficiency, energy conservation and environment protection.
In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Gypsum is interground with the clinker in order to control the setting properties of the cement.
The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill - built to last, reliable and energy-efficient - is the optimum solution when it comes to performing several process steps in one unit.
