cement temperature in ball mill
Approach to High Temperature of Cement Ball Mill. 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

Cement Manufacturing Process
The clinkers are of size of about 5-10 mm. They are fed to grinders in order to grind them to reduce their sizes. The clinkers are fed into ball mill or tube mill along with powdered gypsum. The gypsum acts as a regarding agent so that the resulting cement does not set quickly when it comes in contact with water.

The method of grinding cement may also influence the hydration kinetics. Cements ground in high pressure roller mills set faster than in ball mills, because of higher reactivity of C 3 A and C 3 S phases, and a lowered rate of decomposition of CaSO 4.

AM signifies the temperature at which liquid formation starts, the nature of liquid formed and the color of clinker formed. The lowest temperature is obtained at AM equal to 1.6, which is the optimum for clinker formation and nodulization. Higher the AM, lighter the color of clinker (cement). Normal range of SM is 1-2.5.
