Advantage 1

High efficiency and less wear and tear. Roller compacted materials directly onto the grinding disc, so power consumption is low. Compared with ball mill, it saves energy consumption by 30% ~ 40%. Material of the roller and liner is high quality, so life lime is long.
Advantage 2
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.
Advantage 3
It is with 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 National Environmental Protection.
Advantage 4
This mill itself can crush, dry, grind, classify and transport, 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.
