Vertical milling machine belongs to the relatively common grinding equipment, is used in chemical industry, building materials, metallurgy, mining and other industries in the grinding of mineral materials, which has made a great contribution. Vertical grinding machine is welcomed by the market because of its variety, large selection, complete function and environmental protection. As a large mechanical equipment, once the use of too long, it is easy to appear a variety of problems, such as low powder yield.

In the process of grinding, the yield of vertical grinding machine directly affects the production efficiency of the equipment. That is to say, once the powder yield of the grinding equipment decreases, it will directly lead to the reduction of production efficiency, thus affecting the user's income. Therefore, if such a problem occurs, we must timely check the cause and solve, in order to ensure the normal work efficiency of the Raymond mill.

First of all, in the vertical mill in the production of flour, once appear, underpowered loose or drive belt, wear and tear, it would be easy to cause the spindle speed is not stable, will appear the phenomenon of deceleration, even if there is no timely discovery, you will slow down the material grinding speed, resulting in the vertical mill flour yield decrease.

Secondly, the vertical mill accessories in its operation also play a very important role. If the vertical mill accessories wear phenomenon, will also affect the rate of powder equipment. For example, the vertical mill knife and grinding roller these wear parts, if their wear is more serious, it will appear shoveling material, grinding roller can not play a good grinding effect, so there will be low powder yield.

In addition, the vertical mill powder lock will also affect the yield. If the powder lock is not adjusted to the correct position, there will be a loose seal, powder suction phenomenon, thus greatly reducing the vertical grinder powder yield.

Comprehensive above, leading to the reduction of the vertical mill powder rate, in addition to the reasons of the equipment itself, but also related to the daily operation, materials, so when we use the vertical mill, we should adopt the correct operation method and choose suitable materials, so as to better play the performance of the Raymond machine.
