The cold water link should be taken seriously in the operation of cone ball mill
- Apr 28, 2018 -

Cone ball mill is a kind of fine grinding equipment, mineral processing equipment of ball mill equipment in the process of grinding cement work, need timing quantitative add cooling water in ball mill, so why do this?

There are three main types of cooling water in a conical ball mill: first, because of the large amount of heat energy produced by grinding cement, the temperature of the internal and cement minerals will also increase. When the temperature reaches a certain value in the cement ball mill, gypsum dehydration can occur, which greatly affects the effect of cement coagulation. When the cooling water is added in the right amount, the internal temperature of the cement ball mill will decrease, and the strength of the cement will be increased.

When the conical ball mill is working, a layer of air film will be formed on the surface of the cement to prevent the adsorption of the mineral particles by electrostatic precipitation. Once the temperature is increased, the film is destroyed by electrostatic effect, which can cause the accumulation of particles and even adsorb on the grinding ball and lining board, reducing the working efficiency of the cement ball mill. At this time, need if the cooling water to avoid the occurrence of static electricity phenomenon.

Cone ball mill in cement grinding, the grinding temperature is higher than the temperature of the raw material, together with a cement grinding fineness of fine temperature is very high, a cooling water can make the wall cooling, won't make plate gap between smaller because of thermal expansion, will prevent the lining board into a bump and phenomena such as tensile plate bolt, hollow shaft temperature rise is likely to cause safety accidents, more serious, so add cooling water is for the purpose of safe production.
