Coal is an important energy source around the world. It is widely used in metallurgy, chemical industry, cement, electric power, heating, boiler and other industries.
It is used to produce clean coal powder, activated carbon, humic acid and so on. Clean and efficient utilization of coal has been officially listed in the Plan, and there is a broad prospect for further coal processing in the future.…Pulverized coal to 150-200mesh and sprayed into the furnace can burn more fully. Impurities can be effectively removed in the grinding process, and the burnout rate is higher.
(1) Grinding Stage:
Moist coal should be dried first, and then sent to the main grinding room for grinding. The fine powder after grinding is classified by the analyzer under the action of the air flow of the fan, and the qualified fine powder enters the collection stage through the air outlet pipeline.
(2) Collecting Stage:
The fine powder with qualified fineness enters the pulse dust collector. It is separated by inertia force and falls into the bottom of the ash bucket. Residual dusty gas enters the bag filter area. With the extension of filtering time, dust will accumulate on the surface of the bag. The solenoid valve will flush compressed air into the bag quickly, shake down the dust on the surface of the bag, and all the dust will fall into the ash bucket, collect and discharge centrally.
(3) Conveying Stage:
The finished pulverized coal collected by dust collector is sent from screw conveyor to plate chain hoist, and then into finished material tank. The dust gas in the tank is collected by the top dust collector, the finished product is stored, and the clean gas is discharged.
(4) Finished Product Stage:
The pulverized coal obtained from the powder can be directly sent to the customer for on-site use without additional downstream processing procedures.
