It is understood that, last year, the national cement clinker production reached 12.8 tons. Among them, the kiln cement clinker output of 9.6 tons of cement clinker. In the process of cement production, most of the raw materials to be broken, such as limestone, clay, iron ore and coal etc.. Limestone is cement production, the largest amount of raw materials, mining of large size, high hardness, so crushed limestone in cement plant material crushing occupies important position. Reasonable selection of the crushing process of crushing equipment and grinding equipment is very important. Before the material enters the grinding equipment, as may be the bulk materials broken to small, uniform particle size, in order to reduce the load of the grinding equipment, and improve the yield of Fen machine. Material crushing, it can reduce the process of particles with different size segregation phenomenon in transportation and storage, of uniform composition of raw materials, ingredients to improve the accuracy.
The processing of cement clinker still needs the support of Raymond Mill.
In the process of cement production, material grinding power consumption accounts for about 70% of the comprehensive energy consumption, directly affect the manufacturing cost of cement. In an increasingly tense energy, prices continued to rise in the circumstances, actively adopt new technology and new process, improve the yield of grinding system, reduce the unit power consumption is to reduce production cost and improve the economic efficiency of enterprises is the most effective way. How to actively adopt new technology, new technology, new materials, greatly improving the grinding efficiency and decreasing the electric energy consumption cost, is placed in front of the cement engineering and technical personnel of an urgent task. Feeding size is an important parameter Raymond mill grinding efficiency. Especially for cement grinding process, because the grinding material physicochemical properties and microhardness different, easy to wear index deviation on the raw material composition of the material. So we must take reasonable means, the implementation of pre grinding material pretreatment, narrowed into grinding size more crushing and less grinding, Raymond mill storehouse broken all or part of the move to complete, can greatly improve existing grinding system output, reducing power consumption of grinding.
With the development of science and technology, industrial slag cement demand is increasing, the milling machine manufacturers according to the present situation, development of various milling machines are used to cement pregrinding processing to high yield and high production effect. Shanghai Ding Bo has a milling machine for many years production and sales history of manufacturers, first proposed by vertical milling machine, vertical mill) alternative high stable Raymond mill used in cement pregrinding, effectively improve the 40% - 60% of the output of cement grinding and process design reached world leading level, by users praise.
The processing of cement clinker using vertical milling machine is no longer but from the aspects of environmental protection and emission reduction considering, we r & D and production of large-scale environmental protection cement clinker grinding machine - vertical milling machine energy saving and environmental protection, convenient operation, more stable performance, higher capacity, vertical milling machine to bring the cement industry is tangible benefits to promote.
