Ball mill water spray can improve the efficiency of the reasons

When grinding cement, a lot of heat is generated. The effect of high temperature on cement quality and grinding efficiency is not good and affects the output of the ball mill. Therefore, water should be sprayed into the engine room, and water is atomized and sprayed into the mill with high-pressure air. This effectively removes heat from the mill and achieves internal cooling.

Water is a surface-active substance, which easily disintegrates the agglomerates of the particles and prevents the inclusion of the material on the grinding bodies.

The water in the mill is determined according to the temperature in the mill. Generally, no water is sprayed below 1000C.

In addition, the amount of water spray according to the temperature of the clinker into the mill, accounting for about 1% -2% of the amount of cement, and completely sprayed into the mill water evaporation, no residual water.

Water can be sprayed from the grinding head or the tail water can be sprayed. When the temperature of the incoming material is high, it is advantageous to spray water from the grinding head, and in general the water is sprayed from the tail.

Mill water spray can increase production capacity by 5%-10%.

The addition of grinding aids to the mill can increase the production capacity by about 10%. Generally, triethanolamine is used, and the blended amount accounts for 0.04%-0.1% of the milled material.
