Long term exposure to such a high temperature brings a certain negative load to the ball mill grinder. Only the miner does a good job in the cooling work of ball mill grinder in the summer, can the ball mill grinder maintain a long period of stable operation. So how do we prevent the abnormal high temperature of the ball mill grinder 1.In the grinding process heat will be generated and the cement will be heated up. The temperature of the cement leaving the mill will be dependant on the temperature of the materials (especially the clinker) fed to the mill and to features of the mill and the grinding process. It will typically be in the range from 90 to 120 deg. C. At this.
