This equipment are mainly applied to the powder processing of mineral products in the industries of metallurgy, construction materials, chemical, and mining, etc. And the grinding Mills can produce powder from various non-flammable and non explosive mineral materials with Mok's hardness below 9.3 and humidity below 6%, Final fineness in 30-400 mesh can be between arbitrary regulation, such as quartz, feldspar, calcite, talcum, barite, fluoride, cinder, white lime, cement clinker, activated carbon, dolomite, granite, soft coal, coking coal, lignite, magnesia, chromium oxide green, gold ore, red clay, clay, kaolin, coke, coal Gangue, porcelain clay, fluorspar, bentonite, diabase, shale red stone, basalt, gypsum, graphite, heat insulating material, etc.

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. The system works under negative pressure, so there is no dust going out.

Firstly, raw material should be crushed by jaw crusher to the size specified, and then the crushed stuff is elevated into a hopper from which the stuff is loaded, through the vibrating feeder, evenly and continuously into the grinding chamber for power processing. After this, the ground stuff is carried by the air into the separator for screening. The fine powder are blow into the cyclone collector and are poured out through the output powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The set's airflow system is closely sealed up and circulated under condition of negative pressure.
