What Is Air Swept Coal Mill. The air-swept coal mill is also called a coal grinder. It is the main equipment of the cement plant, used for drying and pulverizing coal powder.It mainly consists of the feeding device, main bearing, rotary part, transmission device, discharging device, high-pressure starting device, and lubrication system.
Dust is the main pollutant from the cement industry. Many links in the cement production process, such as raw material crushing, raw meal grinding, clinker calcination, cement grinding, etc., have different degrees of dust spillover.Among them, the clinker calcination stage has the most serious dust emission degree, accounting for …

Capture involves directing the incoming air flow through the generated dusts to allow capture of the dust. Thus, the mass and velocity of the air flow must be sufficient for this purpose. Last, the incoming air flow must be sufficient to provide control of the captured dust and convey that dust/air mix into the ducting. 4. Sufficient filter area
