Ball mill and vertical roller mill,which is better machine in cement production lines

Vertical roller mills and ball grinding mills are the main milling equipment, that are widely discussed in cement production lines, but the electricity consumption of grinding equipment during grinding can account for 65% to 75% of the total electricity consumption of cement production, plus The demand for energy saving and emission reduction is becoming more and more strict, and the grinding system will be an important part of the implementation of energy saving and consumption reduction in cement production lines. For cement companies, tapping the energy-saving potential of the grinding system has become key.

In the major systems of the grinding system, the energy-saving effect of the vertical grinding system has received much attention and recognition. In recent years, the discussion of the “ball-free trend” has been a typical representative. Some experts believe that cement vertical mill, as two new types of high-efficiency and energy-saving grinding equipment, is the mainstream equipment in cement production in the future, and will surely be more developed and popularized, and the era of grinding with steel balls and ball mills. Will end. For this point of view, Gao Changming, senior consultant of China Cement Network, agreed in the article "Review of the application history of vertical mill in my cement industry". He said that in cement grinding, the energy-saving type of cement, cement production capacity and total weight of system equipment The comprehensive advantages of system installed capacity and unit installed capacity are destined to replace the objective development law of traditional ball mills.

In the meantime, more than 70% of the cement production manufacturers choose vertical grinding, and only 8% of the manufacturers choose. Compared with the previous, the cement vertical grinding has gained more and more recognition, but far below the level. . The reason is mainly that many cement companies have insufficient understanding of cement vertical grinding, and that the so-called vertical grinding cement performance is "poor" than ball milling cement. This misunderstanding has also happened in developed countries. However, after research, the developed family found that, in fact, the essence of this problem is due to the emergence of vertical grinding cement. There are two need between cement enterprises, commercial concrete enterprises and construction enterprises. Coordinating and honing the appropriate processes is a new problem that has emerged in the progress of science and technology and can be properly solved or endured. According to the relevant research experiments and a large number of production practice results, for each of the two specific cement vertical mills, the cement and the market produced a coordinated running-in period, usually about 3 months, comparing It will not exceed 6 months, so it is actually a problem that has already occurred and has been solved. The cement industry inside cannot be denied the cement vertical mill because of this misunderstanding.

Due to its high efficiency, energy saving and superior performance, vertical mill will replace the ball mill in cement production in the future and become the main grinding equipment in cement production.
