LM vertical roller mill for coal grinding is more cost effective , and LM vertical roller mill can save 30%-40% in energy consumption compared with ordinary mills. Vertical roller mill is suitable for pulverized coal boiler, blast furnace injection, coal chemical industry, lime kiln, metallurgy, electric power, cement and other industries, is a multi-functional, bearing thin oil lubrication system of vertical mill. LM vertical coal mill has six models: LM130M, LM150M, LM170M, LM190M, LM220M and LM240M, with a production capacity of 10-50t/h and a finished particle size of 180 mesh.
Technical parameters of LM vertical roller mill
LM vertical roller mill customer case
A company in the United States that makes the preparation of blast furnace pulverized coal injection needs to be blown into a mixed type of bituminous coal + anthracite coal mixed injection, with an injection volume of 170kg/thm. The company chose the LM1700M model mill, the working principle is that the raw coal is sent to the mill through the sealed quantitative coal feeder, the hot air from the heating furnace is sent into the vertical roller mill from the seal, and the ground raw coal is fully heated and exchanged in the roller mill, and the pulverized coal is sorted at the separator, and the fineness meets the needs of the project with the airflow into the explosion-proof gas box pulse dust collector is collected, and then transported to the next link through the discharge port, and the coarse coal powder that does not meet the particle size requirements is returned to the grinding disc for grinding again. The whole process runs under negative pressure and closed state, with low noise and no dust spillage.
Advantages of LM vertical roller mill
- Low investment cost and low operating cost. The machine integrates crushing, drying, grinding, grading and conveying, and the work is to crush the material directly on the grinding disc, and the power consumption is low.
- Long service life. The grinding roller sleeve is used to avoid direct contact between the grinding roller and the grinding disc, reduce wear, and the grinding roller sleeve can be used on the reverse side, with a long service life.
- High powder selection accuracy. The powder separator adopts cage powder separator and conical rotor powder separator.
- Clean and environmentally friendly. The whole machine is closed and negative pressure when working, no dust overflow, and low noise pollution.
LM vertical roller mill suitable materials
