The vertical roller mill (VRM), including powder separation and crushing subsystems, is used extensively for intermediate crushing of minerals in several industries such as cement, electric power, and chemical. Compression crushing is also the main crushing mechanism in the VRM, but there is also shear force between grinding roller and particles.
Composite Metal Ceramic Wear Parts for Cement Industry Vertical Mill Tires, Tables, Rollers, Holders, Seals, Clamps Bolts Vertical Grinding Mill Accessories 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.
However, the unit cost for wear parts for a ball mill is much lower than for a vertical roller mill. For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically EUR per ton of cement.
Depending on the abrasiveness of the material to be ground and areas to be protected, different wear materials are used on our vertical roller mills. The grinding elements are primarily made of alloy cast iron as per DIN 1695, hardfaced cast iron or composite materials with highchromium inserts in ductile base materials.

than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement. Taking into account that VRM usually have a bigger output than ball mills, it can be declared that the major part of the cement production with newly installed mills comes from ...
industry with largescale plants. Until now, various types of crushing equipment have been developed to meet the requirement of the industry, such as jaw crusher, cone crusher and vertical roller mill, VRM [35]. Among these devices, VRM plays an important role in cement, accounting for more than 55% of China's cement raw meal market ...
The vertical roller mill (VRM), including powder separation and crushing subsystems, is used extensively for intermediate crushing of minerals in several industries such as cement, electric power, and chemical. Compression crushing is also the main crushing mechanism in the VRM, but there is also shear force between grinding roller and particles.
