Approach to High Temperature of Cement Ball Mill

3/25/2013 5:29:19 PM

In the operation of cement ball mill, the stop can cause a large temperature difference on the mill body, resulting in significant thermal stress and thermal deformation, and sometimes even cause mechanical damage to the ball mill, such as the geometric deformation of the liner. In addition, the heat of cement ball mill transmitting to the main bearing can increase the temperature of main bearing.

The grinding ability of cement ball mill will reduce in accord with the increasing temperature. In the grinding area with higher fineness, the tiny particles inside the cement will rub against each other to produce an electrostatic adsorption phenomenon, in addition to uniting with each other, they will be further adsorbed on grinding bodies of cement ball mill, which can form a so-called buffer layer which can significantly reduce the grinding effect of cement ball mill; and the higher the temperature is, the more serious the grinding effect will be.

If the temperature of grinding cement is too high, you can use a cement cooler to reduce it. Cold water with temperature of 15 ° C can reduce the cement temperature from 110 ℃ to 65 ℃. You can use a sprinker to cool the grinding body and this can increase the yield of 10% to 20%, and greatly reduce the outlet temperature of cement ball mill so as to improve the collection status of ventilation gas dust.
