Cement Ball Mill system leaking air

Layer thickness control

According to the working principle of the Cement Ball Mill, the Cement Ball Mill mainly crushes and crushes the material, and sweeps it by air. After the material is fed to the grinding disc, a certain layer is formed. When the thickness of the layer reaches a certain thickness, the grinding roller starts to grind. If the material layer is too thin, the grinding stress is too concentrated, and the grinding ability is reduced, which will inevitably cause impact on the roller liner and the disc liner. The Cement Ball Mill vibrates greatly, jumps easily, and also damages the liner, the tension bar, etc. Therefore, it is not possible to control the thin layer. If the thickness of the material layer is too thick, the grinding force will be converted into lateral stress, and the sliding shear will be formed between the materials. The slump of the material bed will increase, the milling efficiency will decrease, and the vibration will be large. The material will not be timely. Grinding and extruding the grinding disc, falling to the spout ring, increasing the circulation amount, the pressure difference is large, the material can not be ground away in time, forming a vicious circle, which can only reduce production and affect the output of the Cement Ball Mill. The author believes that the thickness of the Cement Ball Mill layer is generally controlled at about 50 ~ 80mm. The principle is that the material in the Cement Ball Mill should be ground in time and flow down in time. The system pressure difference should not be too high to ensure that the vibration is within a reasonable range.

Water spray control

The main function of the Cement Ball Mill is to adjust the grinding temperature, stabilize the material layer, and reduce the internal pressure difference. The author believes that according to the actual situation of each factory, it is not necessary to spray water in the mill. As long as the Cement Ball Mill does not vibrate, the pressure difference is not high, and the water spray or water is not properly sprayed, the output of the Cement Ball Mill will be higher. . Of course, the grinding temperature should be within the controlled range. The Cement Ball Mill can spray water on the belt to spray water on the material and spray water inside the mill. If the material is dry, proper water spray will reduce the internal resistance of the mill, reduce the pressure difference, and stabilize the layer. I recommend that you spray water as little as possible or not.

Of course, there are many factors affecting the output of Cement Ball Mills. For example, the mixture structure leads to material segregation, air volume control, hot air temperature control, batching control, etc., which will affect the output of Cement Ball Mills. In short, it should be specifically analyzed according to the actual situation of the factory, specific reasons, and treated separately.
