Vertical roller mills in cement clinker lines

With the development of science and technology, the demand for industrial cement ore powder has been increasing, and various grinding machine manufacturers have developed various kinds of grinding machines for cement pre-powder mill processing, to achieve high yield and efficient production effect.SBM Heavy Machinery, a manufacturer with many years of grinding machine production and sales history, took the lead in proposing the use of vertical grinding machine, vertical roller mill to replace the high stability ore ball mill for cement pre-powder mill, to effectively increase the cement grinding output by 40%-60%, and the design process has reached the world leading level, and has been praised by users.SBM Heavy Machinery has developed environmentally friendly large cement clinker mill, vertical roller mill, specializing in the processing of cement clinker, to make it used again. Especially for cement grinding process, due to the different physical and chemical properties and microhardness of the material to be ground, the index of abrasiveness is worse than the material in the composition of the raw material. Therefore, it is necessary to take reasonable technical means to implement pre-grinding material pre-treatment, reduce the grinding particle size into the mill “more crushing less grinding”, the mill a bin of crushing function part or all moved to the outside of the mill to complete, in order to greatly improve the existing grinding system production, reduce grinding power consumption. Pre-grinding is to pre-mill the material before the ball mill with other crushing and grinding equipment, move the work of the ball mill coarse grinding silo to the pre-grinding treatment, use high efficiency grinding equipment instead of low efficiency ball mill part of the work, reduce the particle size of the clinker into the mill, in order to improve the output of the grinding system and reduce electricity consumption. SBM heavy machine vertical grinding mill special cement clinker industry, coal gangue powder, fly ash processing, grinding station and other high-volume powder production. It absorbs the advanced technology of Europe and combines the company’s advanced mill design and manufacturing concept and market demand for many years, after years of deliberate design and improvement of large grinding equipment. Cement clinker mill, vertical roller mill adopts a reasonable and reliable structure design, with advanced technology process, integrating drying, grinding, powder selection and lifting in one, especially in the large-scale grinding process, to fully meet customer needs, the main technical and economic indicators reach the international advanced level. During the cement production process, the material grinding power consumption accounts for about 70% of the total power consumption, which directly affects the cement manufacturing cost. Under the circumstances of increasing energy tension and rising electricity prices, the active use of new technologies and processes to improve the production of grinding systems, reduce unit power consumption, is an effective technical way to reduce production costs and improve the economic efficiency of enterprises. How to actively adopt new technology, new technology and new materials to greatly improve the production efficiency of grinding system and reduce the cost of power consumption is an urgent task before the cement engineering and technical personnel. The particle size of the incoming material is an important process parameter limiting the grinding efficiency of the mill.
