Ultra fine ring roller grinding mill can be used in more than 300 kinds of minerals 300-2500 mesh powder grinding, such as: gypsum, calcium carbonate, dolomite, limestone, kaolin, marble, bentonite, zeolite, fluorite, graphite and so on. For ultra fine powder making, there are too many grinding mills can be used, for example, Raymond mill, ball mill, vertical roller mill. However, ring roller grinding mill process stone powder has these advantages as following:
1. Low Investment Cost
This ring roller grinding mill itself can crush, grinding, classifying, so the system is simple, and occupation area is about 50% of ball mill system. In addition, it can be installed outside, so it will reduce a large number of investment costs.
2. Low Operation Cost
Our ring roller grinding mill is less wear and tea, so the roller is not in direct contact with the disc, and material of the roller and liner is high quality, so life lime 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
It is equipped with automatic control systems, so remote control makes it easy to operate. And there is just one device was equipped,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 ring roller grinding 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, and reduce the downtime loss.
7. Environmental protection
The ring roller grinding mill is small vibration, low noise, and the overall sealing. The system works under negative pressure, so there is no dust going out. It meets the requirements of the state environmental protection.
