Air Swept Coal Mill


Usage of Air swept coal mill:
The structure of Air Swept Coal Mill :

our factory manufactures has been improving day by day after years of practical experience and continuous improvement. After making significant improvements to traditional air-swept coal mill and possessing all features of ball mill, compared to the same specification mill other manufacturer produce, the capacity of our mill has increased greatly with discharging material more fine and increased specific surface area so as to realize high yield, high fine powder and supplying a new energy-efficient grinding equipment for users.
Air Swept Coal Mill is widely used in grinding coal operation of metallurgy, cement, power, mineral processing, new materials, fertilizer and glass ceramic industry. It is a kind of special equipment which crushes and grinds coal with the function of drying simultaneously.

Feature and Benefits of Air Swept Coal Mill:
1. Optimize the support system to improve the lubrication structure and reduce the system resistance.
2. The lubrication of main shaft bushing of mill adopts hydraulic oil station which extends the service life of alloy tile; meanwhile, the use of hollow shaft saves oil by 90%.
3. The main bearing block of mill adopts cooling water circulating device to cool the bearing so as to avoid decreasing the working life of bearing because of overheating of materials.
4. Reasonable distributions of steel ball and cylindrical shell length increase production by 15% to 25%.
5. Lowers power dissipation per unit yield and saves 20% to 30% electricity consumption.
6. Using a new type of liner material to increases wear resistance; extends liner life and reduces the number of replacement of wearing parts.
7. The flexible connection between reducer and pinion is easy to keep balance with high adaptability to the environment which does n’t need lubrication and has a better performance to compensate the relative displacement of two shafts.
8. Professional reducer matched with mill with high carrying capacity and continuous high-load work.
9. The use of advanced control system makes start and transmission smoothly and can get the best use effect and economic benefit.
10. The use of insulation device reduces heat loss.
