Under normal operation, due to the repeated impact and friction of the medium in the cylinder, the temperature in the mill increases continuously, resulting in the generation of water vapor for water containing materials.

If the ventilation effect of silica sand mill is not good, the water vapor cannot be discharged in time, and the water vapor will adhere to the silica sand mill liner and steel ball, resulting in ball paste or grinding.

Therefore, it is necessary to control the ventilation volume of silica sand mill.The passing effect in silica sand mill is good.It can not only bring out qualified fine materials in time, but also effectively reduce the phenomenon of over crushing and reduce the temperature of silica sand mill.
