The motor of the vertical roller mill drives the grinding disc to rotate through the reducer, and the material falls from the feeding port to the center of the grinding disc. Under the action of centrifugal force, it moves to the edge of the grinding disc and is crushed by the grinding roller. The crushed material overflows from the edge of the grinding disc and is Nozzle ring (air ring) high-speed upward hot air flow is brought into the high-efficiency powder separator integrated with the vertical roller mill. After the coarse powder is sorted by the separator, it is returned to the grinding disc and re-milled; the fine powder is milled with the air flow. Collected in the system's dust collection device, it is the product. Coarse particles and metal parts that have not been carried by the hot air flow fall from the wind ring, are scraped out by the scraper, and then fed into the mill by the outer-circulating bucket elevator to be ground again.
SBM-K cement vertical roller mill is a new type of vertical roller mill developed by our company for the final grinding process of cement clinker. It integrates grinding, drying and classification. Compared with traditional mills, its great advantage is that Low energy consumption: The average power consumption is less than 30kwh / t. Due to the advantages of high grinding efficiency, large drying capacity, stable product fineness, and low operating costs, the equipment has become a new generation of new environmentally friendly cement grinding equipment. SBM-K cement vertical roller mills have various varieties and complete specifications. According to different project scales, they can meet the production needs of 1000-7000 tons of cement clinker per day.
