Vertical roller mill for cement grinding [13]. VRM shown in Figure-1 uses hydraulically hard-pressed conical shape 2-4 rollers against the horizontal revolving grinding table. To enhance comminution, the axes of table and rollers do not traverse in the plane of the
The effect of grinding aids on the comminution of cement is based on the dispersion of fine particles. It is a misunderstanding that grinding aids for vertical roller mills (VRMs) should stabilise the material bed between the rollers and the table by adhesive forces between the particles.
For raw materials and cement clinker, the vertical roller mill is an excellent grinding solution because of the relatively lower cost of installation, ease of operation and maintenance, energy efficiency and product quality. Further, our vertical roller mill solution for cement grinding has an ability to dry, grind and separate within a single

The vertical roller mill (VRM) is popular and widely used for grinding of coal and raw materials. The vertical mill is energy efficient with low specific wear rate. Vertical mill supports drying of the feed material, grinding, separating, and material transport inside the mill.
FL SmidthOK™ Mill, Vertical Roller Mill For Cement Grinding
The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments
The order was for two vertical roller mills (VRM): one type LM 60.4 for grinding cement raw material and one LM 70.4+4 CS, the biggest Loesche VRM built for grinding cement clinker. Loesche worked with Renk to develop the Compact Planetary Electrical (COPE) drive due to the high power requirements of the LM 70.4+4 CS mill.
