Basic equipment structure of the vertical roller mill for cement grinding is the same as the vertical roller mill of raw material and coal grindings. The materials such as clinker and gypsum fed into the mill are ground by compression and shearing forces between the .
In order to reduce the larger pressure resistance (pressure difference between inlet and outlet) of a vertical roller mill, the flow field in the vertical roller mill is numerically simulated by CFD technology. Based on the simulation results, the reasons that led to the larger pressure resistance of the vertical roller mill is studied, offering the theory guide for the technology of reducing ...
Cement grinding is a continuous process: the clinker/gypsum/additions blend is continuously fed at mill entry and extracted as fine fraction from separator. The mass of material sent back to the mill as coarse fraction can be several times the fresh feed, depending on the fineness required and separator type.

The vertical roller mill (VRM) is firmly established in cement plants all over the world. The biggest issues facing plants are not due to the equipment itself, but more to do with how well mill maintenance is understood and how the mill is looked after following commissioning.
Provides effective protection of the separator. The foreign matter trap effectively protects the separator against damage from scrap or other materials and prevents that heavy and oversized material returns to the grinding process. The trap catches all foreign material that has been discharge from the mill such as deformed or broken grinding balls.
Product quality is a function of cement particle size distribution (PSD) and the dehydration of the gypsum within the cement. In the OK mill, parameters, such as mill air flow, separator speed and grinding pressure, can be easily adjusted during operation to control or alter the PSD curve to a profile (steeper or flatter) that achieves the ...
