  • Easy operation and reliable operation;
  • Low operating costs: high milling efficiency, less wear and tear;
  • Easy maintenance: By overhaul cylinder, turn rotating arm, replace the roller sleeve, convenient liner, reducing downtime;
  • Environmental protection: vibration, low noise, and overall equipment sealing system works under negative pressure, no dust spills, clean environment, to meet state environmental requirements;
  • Product quality and stability: Due to the material in the mill residence time is short, easy to detect and control the particle size and chemical composition, reduce duplication of milling, stable product quality, used for grinding white or transparent material, the whiteness and high net product;
  • Low investment costs: The machine set crushing, drying, grinding, grading conveyor in one, the system is simple, compact layout, small footprint, and can open layout, a large number of lower investment costs;
  • Drying capability: The machine uses hot air transportation of materials, therefore, can be dried in a mill grinding material moisture up to 15%, eliminating the need for raw material drying systems, and by adjusting the air temperature, the humidity of materials to meet different Claim.
