Working Principle
Feeding: Pre-ground materials are conveyed to the mill by an elevator.
Grinding: Compression and shearing between trapezoidal rollers and the grinding track.
Classification: Fine particles are separated by the turbine analyzer, while coarse particles are returned to the mill.
Collection: The fine powder is collected in the cyclone and then stored.
Quality Control: Particle size is guaranteed by dynamic adjustment.
Key Advantage: Continuous, automatic, and environmentally friendly process, ideal for modern production lines.
