Sand mill in the grinding process, the appropriate increase in pressure can make the grinding efficiency increase, is conducive to obtain the required particle size in a shorter period of time. But the pressure is too large, it will lead to the grinding media wear rate is too large, make the sand mill and other depreciation rate increased. So how to maintain a proper balance between higher grinding efficiency in the grinding process and avoiding the problem of high grinding pressure leading to high wear rate of grinding media is particularly important.

So what are the ways to adjust the grinding pressure of the sand mill?

First of all, the factors affecting the grinding pressure of the sand mill is the rotational speed of the sand mill, when the rotational speed is increased, the collision between the material and the grinding media, shear force will increase significantly, the internal material between the extrusion and compression are also frequent, and at the same time, a higher rotational speed will allow the material to pass through the rate is reduced, which significantly increases the cylinder pressure of the entire grinding cylinder.

Secondly, it must be noted that the sand mill due to improper cleaning or cleaning is not clean, there will be a screen clogging situation, so that the material discharge speed is greatly slowed down, the grinding pressure of the entire grinding cylinder soared sharply. Regular necessary cleaning and grinding before the sand mill clean can reduce the clogging rate of the sand mill, so that the material discharged more smoothly, through this operation also solves the situation of abnormal pressure of the grinding cylinder, so that the grinding pressure of the sand mill has been effectively adjusted.

Furthermore, part of the sand mill can adjust the spacing between the rotor and the grinding cylinder, when the gap increases, the passing speed of the material is slow and the pressure will be greater. When the gap increases, the flow rate of the grinding media and materials to speed up, the rotor rotation process of the pressure will be relatively small, according to the basic requirements of the pressure when grinding to flexibly adjust the grinding gap, so that the efficiency of grinding and grinding loss ratio in a lower range.

Can not be ignored is the sand mill lubrication processing, and the pressure of the grinding process also has an important link to the sand mill work on a regular basis lubrication processing, not only can make the internal operation of the sand mill is more efficient, but also reduce the sand mill itself wear and tear aggravated to reduce the material and grinding media depreciation, in the grinding process of grinding pressure can also be reduced.
