At present, the domestic use of the large grinding machine is Vertical Roller Mill. The milling machine can realize precision grinding and large production capacity. It is the preferred product of large grinding work at home and abroad. Vertical Roller Mill is a kind of ideal equipment for large grinding. It is widely used in cement, electric power, metallurgy, chemical, and nonmetallic mineral industry. It sets the crushing, drying, grinding, grading conveying into a whole.
The world's first Vertical Roller Mill was invented by the Germans in 1920s. In 1980s, China's relevant research institutions put forward to vigorously promote Vertical Roller Mill advice in the cement industry. Moreover, there were also some manufacturers who have introduced their own Vertical Roller Mill products. But at the time of the R & D level limitation, then, the Vertical Roller Mill products is inevitable to have some technical defects. Therefore, many cement manufacturers finally again turn to the ball mill.
In recent years, along with the great improvement of milling machinery research and development technology, the Vertical Roller Mill technology of mill production enterprises has matured. Vertical grinding technology advantages are also increasingly prominent. In this situation, the domestic mill production enterprises learn the successful experience from the foreign countries, and do the major technical reform. They also have re-introduced the grinding products, which are made with their relevant patent technology. And they are gradually accepted by domestic cement, electric power, chemical industry, and becoming the preferred equipment for grinding industry.
So far, China has developed a variety of Vertical Roller Milling machine models, such as LGM and LGMS type Vertical Roller Mill, MLS and MLK type Vertical Roller Mill, LM Vertical Roller Mill equipment and so on. These all have independent intellectual property rights. And they are successful to be used in the cement industry’s raw materials, coal, slag and grinding operation. In China, the Vertical Roller Mill industry is in the vigorous development. It will greatly pull low the imported price of Vertical Roller Mill.
The above is the introduction on the current development of Vertical Roller Mill in China. Under the current circumstances, our Vertical Roller Mill will be more advanced in the future.
