Technical Requirements For Grinding Mill

The air volume of the grinding mill generally requires 35000~45000m³/h. If the wind speed and air volume of the mill are too large, the fineness of the product selected by the separator is coarse, otherwise it is small, and the output of the single machine is also smaller. low.
