Roller mill GMRC Series coal mill

verticalfor coal grinding

Coal vertical mills also called coal mills, which are specialized in superfine grinding of raw coal and bituminous coal materials in cement plant, power plants, steel mills and other fields. Capacity :5-70 t/h fineness :80 μmR 3% Power :18-22 kWh/t Application :Power plant, cement plant, lime plant and other coal grinding Enterprises Process introduction GRMC coal vertical roller mill produced by CHAENG adopts a special structure design and production technology, and the quality is up to the leading level in China. It is the first choice equipment for grinding raw coal and bituminous coal. 1. The raw coal is screened from the raw coal storage yard and then dropped onto the belt conveyor through the grid screen. After the iron is removed by the electromagnetic iron separator, the belt conveyor sends the raw coal into the original coal bin for storage. 2. After the pulverizing system has been started, open the rod valve at the bottom of the original coal bin, and start the sealed measuring adhesive taped coal feeder, and then the raw coal enters into the coal vertical mill for drying and grinding. 3. The hot air from the hot stove or waste gas of cement production line are exhausted into coal vertical mill by fans, exchange heat with raw coal in mill, and then take pulverized coal up to separator for separating. Substandard coarse pulverized coal falls down to grinding table for regrinding, and qualified pulverized coal enters into pulse dust collector of explosion proof air box along with gas flow, and is discharged into pulverized coal bin through a grid wheel.
