function: cement mill is a drive 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. process: raw materials are fed to the mill in right proportion with the help of weighfeeders.dehydration of the gypsum added to the cement 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 fed to the mill and to features of the mill and the grinding process.air flow through the mill is one medium for cement transport but also removes water vapour and makes some contribution to cooling. grinding is an energy intensive process and grinding more finely than necessary wastes energy. cement consists of clinker, gypsum and other components mostly more easily ground than clinker.nov 01, 2017 cement mill grinding media. dear experts, want to know about the GM size wise percentage distribution in a chamber close circuit opc ball mill. mill dim. 3.4 12.5. media load 128 MT high chrome. also let me know how do the supplier selected as max. ball size in this mill? please share the formula as well.
