Description of Air Swept Coal
Mill:
This air swept coal mill is specially used to dry and grind coal.
And it is mainly consist of feeding device, main bearing, rotary
part, transmission device, high voltage starting device, and
lubrication system.
Raw materials enter into the mill by the feeding device, and
the hot air gets into the mill through the air tube. When the mill
cylinder begins to rotate, coal and hot air can exchange heat with
each other. Meanwhile, the coal will be crushed and grinded in the
air swept coal mill. While the coal is grinded, fine powder will be
taken by the hot air out of the mill through the discharging
device.
Featuring rational structure and high grinding efficiency, this air
swept coal mill is an ideal choice for coal pulverization.
Air-swept coal mill is the equipment used for grinding and drying
coal with different hardness and it is mainly composed of feeding
device, principal axis, rotating part, transmission part,
discharging part, high-pressure starting device and lubrication
system. Air-swept coal mill is widely used cement, building
material, thermal power generation, metallurgy and chemical
industry and it has the reasonable structure and high powder
grinding efficiency, so that it is the ideal equipment for making
coal powders.
This grinding mill adopts edge driving and the electromotor rives
the grinding mill through the reducer and rack wheel and pinion.
The grinding mill adopts air-swept structure with a drying bin, so
that it had strong adaptability to the water containing in the raw
coal. Inside the powder grinding cabin, the ladder lining board,
double-ladder lining board and ripple lining board are arranged in
a combined type, thus improving the powder grinding ability of the
grinding mill. The feeding device adopts window-shade structure
that the air can obliquely go in, thus enhancing the heat exchange
ability of the grinding mill and effectively avoiding the material
blockage of the feeding mouth of the coal mill.
