The research and development and production technology requirements of Vertical Roller Mill Operation are very high. In the 1980s, relevant research institutions in China proposed to promote vertical mills in the cement industry. At the time, some manufacturers also launched their own vertical mill products. However, under the limitations of the research and development level at the time, the vertical mill products at this time had inevitable technical defects, so many cement manufacturers finally switched to ball mills.
With the substantial improvement of the grinding machinery research and development technology, the vertical grinding technology of foreign mill manufacturers has become more and more mature, and the technical advantages of vertical grinding products have become increasingly prominent. Under this situation, domestic mill manufacturers have learned from foreign successful experiences and carried out major technological reforms. They have also re-launched vertical mill products with their own patented technologies, and gradually accepted them for the domestic cement, electric power and chemical industries. , become the preferred equipment for industrial grinding.
The vertical grinding system has a simple process, compact layout, small building area, and covers an area of about 70% of the ball mill system. The building space is about 60% of the ball mill system and can be arranged in the open air, which directly reduces the investment cost of the enterprise. And the vertical mill itself has a separator, no need to add a separator and lifting equipment. The dust-laden gas can be collected directly from a bag filter or an electric dust collector.
