Coal Vertical Mill 40 T/H Vertical Coal Mill Energy-Saving High Production Low Consumption Coal Mill
Product Introduction:
Vertical mill is an ideal large-scale grinding equipment widely used in industries such as cement, electricity, metallurgy, chemical industry, non-metallic minerals, etc. It integrates crushing, drying, grinding, and grading transportation, with high production efficiency. It can grind block, granular, and powdered raw materials into the required powder materials.
Product advantages
1. High grinding efficiency and low power consumption;
2. Low metal consumption per unit product;
3. The process flow is simple, and the functions of material grinding, drying, and powder selection are completed simultaneously;
4. Small footprint, compact layout, lightweight system equipment, and low investment in civil construction.
Process Introduction
1. The raw coal is sieved through a grid screen in the raw coal yard and falls onto a belt conveyor. After being removed by an electromagnetic iron remover, the belt conveyor sends the raw coal to the raw coal bin for storage.
2. After the pulverization system has been started, open the rod valve at the bottom of the raw coal bin, start the sealing metering tape to feed the coal vertical mill, and the raw coal enters the coal vertical mill for drying and grinding.
3. The hot air or cement production line exhaust gas from the hot air stove is drawn by the system fan and enters the coal vertical mill. After sufficient heat exchange with the raw coal being ground in the mill, the coal powder is picked up and sorted at the powder selection machine. Coarse coal powder with poor fineness is re ground on the grinding disc for grinding. Qualified coal powder is collected by the explosion-proof gas box pulse dust collector with the airflow and discharged into the coal powder bin through the grid wheel.
4. The impurities in the raw coal, such as some coal gangue, metal blocks, etc., are discharged from the mill through the air ring and slag discharge port.
