Coal mill, also named as coal grinding mill, is used to grind and dry coal with various hardnesses; Coal powder kiln is mainly composed of feeding device, main bearing, rotating part, gear, discharging equipment, high-voltage start-up device and lubrication system. Coal mill is widely used in industries including cement, power generation, metallurgy industry, chemical industry, etc., with reasonable structure and high grinding efficiency; it is the ideal equipment for coal preparation.
Coal mill equipment is designed for coal mine and ore processing machine, the coal processing to more than 80 meshes. The original design of the mill in circle grinding, Henan Hongxing Mining Machinery Co., Ltd. has not feed and feed from the feed screw Jane and feed chute between the gap to revert also influence the smell of the ring is not only influence the normal production. More serious is to return from the mill of the material, were selected from the powder selecting machine in the feed back, which contains part of the fine powder. This part of the material accumulation in the basis, such as more than a hollow shaft bottom line, can easily be hollow shaft main bearing, oil pollution, directly affect the lubrication of main bearing. This is the main reason of fever and premature wear of bearing.
This coal grinding machine consists of feeding device, main bearing, rotating part, driving part, discharging assembly, high-pressure starting device and lubrication system. Raw coal is feeding into the mill via the feeding device and hot air goes into the shell through air inlet pipe. As the shell rotates, the coal does heat interchange with the hot air and is crushed and pulverized. At the same time, fine powder is carried out of the mill via discharging assembly by the hot air. The air swept coal mill has a feature of reasonable construction, high pulverizing efficiency and is the perfect equipment for processing coal powder.

Cooling machine is one of important equipment in dolomite calcining equipment system, the device has the function of the activity of the calcined white (1000 ? ~ 1200 ?) out of the rotary kiln through the cylinder rotary drive sufficient heat exchange with the air, making calcined white cooled to below 200 ?. The equipment adopts the countercurrent cooling way, with high thermal efficiency, and it reduces pollution, and improves working environment. Also it has a reasonable structure, smooth operation, strong adaptability, etc. It is widely used in metal magnesium production line, cement production line, the active lime production line, and ceramic sand production line, and other important industrial production.
Because rotary drum cooler has reliable operation and large operation elasticity and a strong adaptable and big capacity of treatment, rotary cooler is widely used for metallurgy materials, construction, food, light industry, chemical, coal, pharmaceutical mining industry. The rotary cooler is used for granulate materials, and it is also used for the way that partly incorporate material, for cool down the sticky paste materials or the higher temperature materials.
Rotary drum cooler is suitable for that after drying compound fertilizer, and makes 65-85? compound fertilizer form balancing and continuous mill apron to contact with cool air adequately and cool off to approach normal temperature by the well-designed inner structure, which makes products packed timely and prevents caking in storage transportation. The cooling method adopts backwash of cool wind, which utilizes induced -draft fan to take out the cool air from the end of equipment and make it contact with material conversely and cool compulsorily at the feed-in part of the equipment in order to reduce the temperature of the material rapidly. It is the perfect cooling equipment of compound fertilizer production, for the good cooling effect, high-output and convenient operation.
