Working Principle
The main engine motor inputs power to the main shaft through the main engine pulley to drive the rotary table of each floor to rotate. The shaft pin drives the three or four-layer ring rollers to roll and rotate in the grinding ring raceway through the rotary table.
The large materials are crushed into small particles by the hammer crusher and then sent to the storage bin by the elevator. The skirt belt feeder evenly sends the materials to the middle of the upper rotary table through the feeding port.
The high-pressure centrifugal fan sucks the external air into the cavity and sends the materials after three layers of crushing into the powder concentrator. The rotating turbine in the powder concentrator makes the coarse particles that do not meet the requirements fall back into the grinding chamber for regrinding, and the fine powder enters the dust collector with the air flow, is purified by the filter bag, and is discharged through the screw in the discharge valve, which is the finished product. The purified gas is discharged through the fan and silencer.

Performance Advantages
High efficiency: Under the same final particle size and power conditions, the capacity is twice that of jet mills and agitated ball mills.
Long service life: The grinding rollers and rings are made of special materials, ensuring a long service life. When grinding calcium carbonate and dolomite, the service life can reach 2 to 5 years.
High safety: There are no rolling bearings or bolts in the grinding chamber, avoiding issues such as bolt loosening or wear of bearing seals.
High precision: The product particle size can reach D97≤5 micrometers.
Environmental friendliness: The use of pulse dust collectors and silencers ensures that dust and noise pollution meet national environmental standards.
