jiangsu pengfei group undertaken the construction of 500000tons per year cement grinding station in Russia, and pengfei group was responsible for the process design, supplying the main equipments of grinding, separating, dust collecting, packing and other systems.
in the contract, it required that the specific surface area met 320 m2/kg, drying system for mixed materials is not separate, and drying and grinding integration mill was designed. this is the new challenge in product quality, production process or equipment structures.
practice shows that the drying and grinding integration cement mill designed specially by jiangsu pengfei group entirely satisfied the requirements in the contract, so it successfully put into operation and acceptance, meanwhile received the good reputation from the owner.
process flow design of 1,000,000tons/year cement grinding plant:
1. designing of clinker grinding production line
after gypsum, clinker and limestone are measured by the belt weigher, they will be mixed together in accordance with particular proportions, and then sent to the stable weighing warehouse. during this process, magnetic metals are removed by the iron remover from these materials. then mixed materials will be sent into the rolling machine to be crushed. after crushed, they will be sent to the powder separator, in which coarse powder will be sent back to the griding mill while the fine one will be sent to the elevator for finished products. finally, they will be sent to finished product storage. meanwhile, dusty gas from the grinding mill will be purified by the environmental protection equipment before discharged into the atmosphere.
2. design of slag grinding production line
gypsum, dry slag and pulverized coal are measured by the belt weigher before mixed together according to particular proportions. mixed materials will be sent to the mill for grinding, and during this process, iron remover is employed to remove magnetic metals in these materials. after grinded, fine powder will be sent to high-efficeint powder separator, while coarse powder will be sent back to the grinding mill. finished cement will be collected by the air tank pulse bag filter, while the fine powder will be sent to the storage for finished products through an elevator. dusty gases from the mill will be used as the first gas to enter into the powder concentrator, which is followed by fresh air. finally, dusty gas will be purified by the air tank pulse bag filter before discharged into the atmosphere.
3. design of mixing fine slag and powder clinker
besides the fineness of powder clinker and fine slag in the grinding production line, accurate measuring and even mixing also need to be paid much attention to. that's why we choose to use the screw measurer as the measuring device and the air slide as mixing device as well as conveying device.
