Cement Vertical roller mill (VRM) is mainly used to grind cement clinker into fine powder during cement production, which can also be used to grind various materials such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite etc.
Cement grinding mill is normally driven by electric motors. The output achieved by a cement mill system varies with the mill power, the fineness of the product and the hardness of the clinker. Cement grinding mill is the last process of cement production, also the most power consumption process.

mill entry for further grinding. Fine fraction is sent to storage as finished cement. This is the typical arrangement of the so called "close circuit grinding", as described in figure 3. Cement grinding is a continuous process: the clinker/gypsum/additions blend is continuously fed at mill entry and extracted as fine fraction from separator.

Aug 13, 2015· Vertical Mills. A significant portion of the cost to produce a ton of cement resides in the grinding costs. The industry standard for decades has been horizontal ball mills which rely upon heavy balls cascading inside a fast turning mill to crush the clinker into the fine cement powder.
The protocol consisted of screening the laboratory mill content after each grinding run to remove undersize, which is then replenished with an equal mass of new clinker until CL becomes constant. For given Blaine fineness, test results have shown that cement ground in the laboratory for a fixed time interval possesses wide PSD curves characterized by spread factor n less than
