In the process of cement production line, the majority of raw materials must be crushed, such as limestone, clay, sand and coal. Limestone is the largest amount of raw materials for cement production, the larger particle size after mining, high hardness, thus limestone crushing at the cement mechanical material crushing plays a more important role. Raw pre-homogenization technology is that during the save, take the process of the material, use the scientific stacker reclaimer technology to realize the initial homogenization of raw materials, make the raw material yard also have the function of storage and homogenization.Raw material preparation: In the process of cement production , produce one ton of portland cement mill need grinding at least three tons of material( including raw materials, fuel, clinker, mixture, plaster), According to statistics, Dry-process cement production line grinding operation consumes power accounted for about 60% of plant power , which raw material grinding accounts for over 30%, coal grinding accounted for about 3%, cement grinding accounted for about 40%. Raw material homogenization: In the process of new dry cement production, the stability of pit entry clinker raw material composition is the premise of stabling firing thermal system, which play the last gatekeeper role about stable raw material composition pit entry.Preheat decomposition: Raw material preheating and partial decomposition accomplished by the preheater, instead of part of rotary kiln, make the kiln conduct gas heat transfer process with stacked state, move to pre- internal heat under the suspension, make the raw material to the Hongxing hot kiln exhaust gas mixing, increasing the contact area of the gas feed, fast heat transfer, high heat exchange efficiency, to improve production efficiency of kiln system, reducing the clinker burning heat consumption.Cement grinding: Its main function is to make cement clinker (and gelling agent, the performance moderator material) grinding to a suitable size (in fineness, specific surface area, said), form a certain particle size distribution, increasing its hydration area, accelerate hydration rate, to meet the cement paste coagulation, hardening requirements.rotating kiln: http://www.hx-jawcrusher.com/pp/protary-kiln.html
