Approach to High Temperature of Cement Ball Mill

       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 of the ball mill, such as the geometric deformation of the liner. Starting the thermal deformation after the stop grinding can produce a certain penetration force, to form the current ripple and its own vibration in the operation; in addition, the heat of cement ball mill transforms to the main bearing can increase the temperature of main bearing.
   The grinding ability of material will reduce in accord with the increasing temperature. In the grinding area with higher fineness, the tiny particles of the cement will rub against each other to produce an electrostatic adsorption phenomenon, in addition to unite with each other, they will further adsorb 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, 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 make sprinkler measures in the grinding body, generally in fine grinding compartment spray. 1% to 2% of the cement production is atomized water, which 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.
