With the unprecedented development of cement industry, the development of grinding machine industry is very quick. The legislative process system of grinding mill process simple, low unit power consumption, cement stable product quality and convenient operation has been all users. In foreign countries, especially the developed countries, the effect of input and output of the mill proceeds quite amazing, which promote the development of foreign cement vertical mill finish grinding technology.

In our country, the promotion and use of vertical grinding mill seems a bit slow. Due to the use of habit, ball mill, roller press as the traditional ball mill grinding equipment, which has more than 100 years of history, especially the low cost, the ball mill cement sphericity Gauguin is let very favour of cement plant. With the development of the times, although the ball mill is very harmful to the environment in the use of the process, but due to lack of funds and technical resources consuming, most enterprises still choose as the main cement ball mill grinding equipment. Two is the number of cement factory by the "cement vertical mill production finished particle shape is not good, the water requirement" remarks by the impact, not comprehensive understanding of cement vertical mill. In fact, the expert points out, some professional major manufacturers through adjusting the grinding disc and the grinding roller design can solve the cement vertical mill product from the spherical particle shape distribution is not good, too narrow issue, so as to improve the vertical mill cement workability.

Cement production line with heavy machine building a 5000t/d in some countries, the equipment adopts 2 cement vertical mill, the cement plant tons of product power consumption is reduced to 78kWh/t~80kWh/t, and the quality of cement are obtained user's consistent affirmation.

From the Southwest University of Science and Technology had done "was informed that the different flow of cement standard consistency water experimental data obtained", actually need the highest content are closed combined grinding system, rather than the vertical mill.

In order to better study the cement vertical mill, ball mill, roller press in the application of the domestic actual situation, some industry experts for the comparative study of the many several grinding equipment, the final result, cement vertical mill finish grinding in power consumption, investment, product performance and other aspects is superior to traditional grinding process, which can meet various needs of the project roller press, ball mill, and compared with the traditional process, the vertical mill finish grinding process is simple, the raw material moisture content and hardness of high adaptability, low yield per unit of installed power, electrical and mechanical equipment quantity are few, has obvious advantages!
