Coal Mill Machines

Summary

The coal mill is the core equipment of the coal pulverizing system in thermal power plants. Its function is to crush and grind raw coal into fine coal powder that meets the requirements of boiler combustion, and then dry and transport it to the burner through hot air. Crush and grind block shaped raw coal (particle size usually ≤ 30mm) into 80% fine coal powder passing through 200 mesh (about 74 μm), increase the specific surface area of coal powder, and ensure full combustion.

Detail
  • Grinding disc. Horizontal rotating platform, raw coal is crushed under centrifugal force. The material is high chromium cast iron (such as KmTBCr26), with a wear-resistant layer welded on the surface.
  • Grinding roller. Hydraulic pressure (10-15 MPa) is applied to compact the coal seam on the grinding disc. The material is alloy steel casting+surface wear-resistant welding, with a service life of 8000-12000 hours
  • Pressure frame. Transmitting hydraulic cylinder pressure to the grinding roller and constraining its movement trajectory, this heavy-duty steel structure is impact resistant.
