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.
Powder Requirements
(1) Production of Clean Pulverized Coal for Boiler Combustion Heating and Power Supply Suitable types: bituminous coal, anthracite, blue carbon, etc.
Advantages: The production of clean pulverized coal for boiler combustion, heating and power supply improves the operation efficiency of small and medium-sized coal-fired boilers to 80%. It can reduce the emission of harmful gases and dust, achieve the national energy saving and emission reduction standards, and at the same time, it can increase the benefits of enterprises.
Fineness: 200mesh, D80-90, according to the requirement of back end combustion
(2) Production of Humic Acid Fertilizer for Agriculture Suitable types: Lignite, weathered coal, peat, etc.
Advantages: Humic acid fertilizer has the advantages of improving soil, improving crop production and avoiding soil consolidation. It is a kind of “green environmental protection” high-tech fertilizer, which realizes the efficient utilization of coal. In recent years, the series of humic acid products are increasing day by day, which are exported to foreign countries and create tremendous value for enterprises.
Fineness: 100mesh
(3) Production of Coal Activated Carbon for Chemical Industry Suitable types: Bituminous coal, anthracite, etc
Advantages: Coal-based activated carbon is widely used in deep purification of drinking water, industrial water and wastewater because of its reasonable pore structure, good adsorption performance, high mechanical strength, easy regeneration and low cost.
Fineness: 200-325mesh, fineness varies according to process requirements
