Air swept coal mill and raw material dryer is composed of feeder part, main bearing, rotation part, discharge part, drive motor, decelerator etc. which is main equipment of cement plant, and used for drying and grinding pulverized coal, also used for grinding Titanium concentrates and high Titanium slag.
Working principle: feeding equipment takes raw material into feeder device, at the same time of material falling, blast pipe brings hot air, and material takes its function of inclined slide down, through hollow shaft and sliding into mill body.
There is a certain amount of grinding media in mill body, and it is taken a certain height because of mill body rotating, utilizing its impact and friction when falling to crush and grind material, at the same time of crushing and grinding, fine powdered particles together with heat exchanged hot air is taken out by ventilation fan through discharge device.
Unqualified rough powder is separated from compound of fine powder and hot air by separator, and back to mill to regrind. Compound of qualified fine powder and hot air is transmitted to cyclone collector, fine powder and hot is separated here.
Features of air swept coal mill
1. Reliable running, continuous operation and large production capacity.
2. Less driving parts, low maintenance fee.
The air swept coal mill is designed according to the advantages of open circuit grinding system, and made a great improvement in traditional ball mill, apart from all advantages of open circuit mill, compared with same specification ball mill, capacity of mill has a great improvement, and powder is fine, specific surface area is increased, realizing high capacity and high fineness, providing a kind of new grinding equipment for production high quality cement.
