Cement manufacturers purchasing clinker grind as an addition to their own clinker at their cement plants. Manufacturers also ship clinker to grinding plants in areas where cement-making raw materials are not available. CLINKER GRINDING MACHINES In the present world there all many machines available to grind the clinker to produce cement. Some of
Process Optimisation is an online application for closed-loop control of a grinding plant. This involves integrated process optimisation which is based on a dynamic process model. This process model provides continuous real-time optimisation of the plant.
Jul 31, 2020 Autoclave expansion is another property of cement that partly depends on the grinding process. More often, it is experienced that cement ground in the laboratory mill shows higher autoclave expansion than the cement produced in the plant mill, even when both of them are having equal amount of gypsum and ground to the same specific surface area.
