● High grinding efficiency and low power consumption
● Less metal consumption per unit of product. the service life of grinding parts exceeds 8000 hours , and can be easily repaired.
● Wearing on roller and liner makes little effect on the output (within 5%).
● Each roller is relatively independent to make pressure and crush the materials on the millstone and it can be implemented part of the work, such as it can reach 70% of rated output when two rolls of the four-roll mill work.
● Separation parts combined with high dynamic and static binding cage separator, raw material fineness control high precision, sensitivity adjustment, the raw material fineness R80μm=10~15%，R200μm=1.0%。
● Strong drying power. By using exhaust gas from kiln , raw material of 7% moisture can be dried. While raw material of 20% moisture can be dried if auxiliary heat source is used.
● Grinding with material bed. Low noise, negative pressure operation, less dust pollution.
