Type: Ball Mill

 Working Principle

Motor runs under the condition that speed reducer drive the Nether millstone. The materials fall into the center of device through lock air feeder, and hot air comes into mill through air inlet. Under the function of centrifugal force, the materials come by the annular chute. The grinded materials will be taken up by air circulation and the bigger powers will fall down for regrinding. Qualified powders will be collected by collecting device as to be final product. Materials containing water will be dried when they contact with the hot air. Different humidity materials can be dried to the requirement through adjusting the temperature or hot air. Adjusting the separator can get the required fineness powders.

Main Features

1. Low investment Cost This mill itself can crush, dry, grind, classify, so the system is simple, and occupation area is about 50% of ball mill system. In addition, it can be installed outside, so it reduces a large number of investment costs.
2. Low Operation Cost

(1) High efficiency: roller compacted materials directly onto the grinding disc, so power consumption is low. Compared with ball mill, it saves energy consumption by 30%-40 %.

(2)Less wear and tear: As the roller is not in direct contact with the disc, and material of the roller and liner is of high quality, so life is long.
3. High Drying Ability As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, it can meet requirements with different humidity.
4. Simple and reliable operation

(1)it is equipped with automatic control systems, so remote control makes it easy to operate.

(2)It is equipment with one device, which prevents the roller from contacting with the liner directly, and avoids the destructive impact and severe vibration.
5. The stability of product quality As the material stays in the mill for a short time, it is easy to detect and control the product particle size and chemical composition, to reduce duplication of milling, stable product quality.
6. Maintenance convenience By repairing fuel tank, rotating the arm, it is fast to replace the roller sleeve, and liner, reduce the downtime loss.
7. Environmental protection It is with small vibration, low noise, and the overall sealing.
