Cement industry the ball mill was really an epoch-making breakthrough as for almost ball mill 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 ball mill.A cement mill or finish mill in north american usage[1] is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.The temperature of the clinker after being cooled drops from 1350 – 1450⁰c to around 120⁰c. the cooled clinker is then transported to clinker silos or hoppers directly by conveyors for storage and later cement grinding process. ball mill the cement ball mill is a horizontal cylinder filled with steel balls or other grinding media. inside the ball mill.

3. grinding: the clinkers as obtained from the rotary kiln are finely ground in ball mills and tube mills. during grinding, a small quantity, about 3 to 4 per cent, of gypsum is added. the gypsum controls the initial setting time of cement. if gypsum is not added, the cement would set as soon as water is added.

For the main bearing of cement mill, it is hoped that there will be a thick insulation layer to block the heat transfer. 5affected by the ambient temperature of the ball mill. the ambient temperature also affects the ball bearing temperature, such as season, location, and even the ventilation of workshop level, will affect the bearing ball mill.
