When entering the mill is too large, the grinding body and the lining plate will adhere, resulting in paste grinding, blocking the grate plate and full grinding.
However, containing a small amount of moisture can effectively reduce the temperature and static electricity of vertical roller mill operation. Therefore, the average moisture of vertical roller mill operation is generally controlled at & lt; 15% is appropriate.
Allowable moisture content of grinding material (for reference only) allowable moisture content of grinding material name rotary kiln and shaft kiln clinker 0.5 granular blast furnace slag 2.0 natural pozzolanic ash 2.0 limestone 1.5 clay 1.0 gypsum 10.06, vertical roller mill operation steel ball grading is unreasonable, which is to realize the impact and grinding of materials with different particle sizes, so as to improve the grinding efficiency, Therefore, the grading of vertical roller mill operation steel ball is very important.
