• cement industry: Nghi Son, Vietnam, 1998,Guangzhou, China, 2005. Loesche developed the 4-roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The develop-ment was first realised in 1970 for grinding mills in the cement industry. This number of rollers also enables operation with only one pair
terms of mill output, thanks to the stabilisation of the grinding bed and the reduction of the related vibration levels. Moreover, these new generation additives can be employed in order to improve the cement's chemical-physical properties and / or to reduce water additions during the grinding operation. 4.1 MILL OUTPUT INCREASE
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

How to choose China vertical roller mill (the output is more than 300t/d) The vertical roller mill has a grinding fineness of 200-400 mesh, so the general processing material yield is large, and the grinding is not as fine as the Raymond mill, resulting in a decrease in yield. The grinding materials generally used for the concrete and cement mixture are ground by vertical roller mill.
Sales of cement are increasing due to growing demand for cement in both the local and foreign markets. The industry realized about 30% and 21% growth in 2009 and 2010 respectively after suppressed demand from previous years. Industry expected demand growth is 20%-25% for the next three years based on the assumptions below. 1.

O in order to prevent flash settingof the cement, and to facilitate the grinding process. The grinding is done in a ball mill. The cement discharged by the mill is passed through a separator, fine particles being removed to the storage silo by an air current, while the coarser particles are passed through the mill once again.
There are two operation modes of the particular cement factory. The first one is when the raw mill is under operation and, in this case, the cooling water flowrate at the cooling tower is 3 t/h. A hot gas from the kiln is fed into the raw mill and a raw material is heated. The second operation mode presumes that the raw mill is out of operation.
