Coal Pulverizer-Raymond Mill
The drying capacity of the pulverized coal mill during grinding is mainly obtained from two aspects. One is the heat generated by the friction with the material during the operation of the mill, and the other is the hot air that can be introduced from the lower vent of the mill to accelerate the pulverized coal. The drying speed.
