Foreign cement enterprises are constantly using high-tech production, vertical grinding machine has long been popular abroad. Driven by scientific and technological progress and the development of The Times, China's traditional cement production line manufacturing mode is undergoing profound changes, cost saving, the pursuit of high yield and high efficiency, cement production line to achieve green and environmental protection are the needs of cement production in this era. Production and management of grinding machine equipment for many years committed to improve the performance of equipment and also to protect the environment, vertical grinding machine production has been to achieve the goal of cement pollution-free production.

Traditional manufacturing thinking and production mode can no longer meet the contemporary market demand, many cement manufacturers continue to eliminate the high energy consumption of the old ball mill, and adopt more energy saving and environmental protection of the vertical mill, through the high and new technology vertical mill to achieve low carbon, pollution-free emissions. Many experts believe that the use of vertical grinding machine cement production is more conducive to environmental protection, in the future vertical grinding machine will be popular in China's cement industry.

The mill feeds too much material, resulting in too much material in the mill, the mill working condition occurs a bad change, it is easy to instant vibration jump stop. Because the waste bin can not be used, when the grinding slag directly into the mill, the vibration after the grinding roll down is large, at the same time, the material thickness is large, the inlet positive pressure, this is because when the grinding slag, coupled with the belt scale feeding, feeding into the mill become more caused by. At this time, a large number of belt scale feeding should be reduced, such as slag spit normal, and then add to the normal, feeding amount is too small, the grinding material is too little, material layer thin. The material buffering capacity between the grinding disc and the grinding roller is insufficient, which is easy to produce vibration. During the trial production of vertical mill, 70% feeding is required due to mechanical requirements, so the feeding is relatively small, which is one of the reasons for the large vibration of neutral mill in trial production. Therefore, it can ensure the smooth operation of the mill by feeding large particle materials. Unstable materials make the working conditions in the mill chaotic, easy to vibration, in order to achieve the smooth operation of vertical mill, one of the important factors is to make the material evenly smooth feeding.
