A. Special grinding curves of grinding roller and grinding disc ensure stable and efficient operation of host machine.

B. Grinding roller takes mechanical position limiter, directly avoiding touching grinding disc. Therefore, destructive collision and violent shocks are avoided.

C. Special sealing design prevents dust from entering the inside of bearing to keep long-term operation of grinding roller.

D. The high-efficiency powder concentrator can freely adjust the particle sizes and ensure the accurate cutting point and reproducibility of products.

A. Fineness of finished products can be adjusted flexibly. Primary powder production can reach D97=10μm-20μm while the next powder separation attains D97=4-5μm easily. Finished products have advantages of high content of fine powder, high whiteness and more compact granularity.

B. Lingering time of materials in grinding cavity is short. The components and fineness of finished products can be measured and collected quickly, keeping stable quality of finished products.

A. Grinding roller grinds the materials directly. Its energy consumption is 10% lower than other types roller mill and 25-60% lower than that of ball mill.

B. No direct touch between grinding roller and disc and the special wearable alloy materials used in grinding roller shell and lining plates grant a long life expectancy of mill and save the costs on quick-wear parts.

C. Automatic control systems like PLC, DCS and Central Control System can be used to operate machines remotely, saving labor force.

A. Because of no touch between grinding roller and disc, there is no clang and slight vibration. The noise is 20-25 decibel lower than that of ball mill.

B. The whole set of system is fully sealed and operates with negative pressure. Besides, it is equipped with pulse dust collector so the exhaust emission completely meets related national standards.
