Coal vertical roller mill

Coal vertical roller mill

Coal vertical roller mill can be widely used in cement, electric power, iron and steel, metallurgy industry etc.. coal vertical roller mill because of its special structure and technology, less dust, the production process of low noise, high output of pulverized coal with grading and excellent combustion performance.

Coal vertical roller mill has the advantages of simple, compact equipment, coal fineness can reach 80 and 3% mu, and the fineness and stability, uniform granularity. Suitable for the type of enterprise: output of cement factory, steel mills, power plants: 5~70 t/h fineness: diameter of 80 mu mR 3% disc: 1200~3500 mm system power consumption: 18~22 kWh/t.

Coal vertical roller mill product advantage

  • With oil lubrication. The grinding roller, prolong the service life of the bearing more than 2.5 times the general vertical mill grinding roller bearings with grease lubrication, but because of raw water is larger, the improper operation is easy to cause the roller high bearing temperature, resulting in grease evaporation metamorphic effects of bearing life. Therefore, SBM lum coal vertical mill using oil lubrication, cooling roller, greatly increasing the service life of the bearing.
  • the product fineness can reach 80 mm, coal vertical mill using the most advanced static and dynamic combined separator, the separator of high classification efficiency, large control room, select powder fineness can reach 0.08mm sieve residue below 3%, can meet the requirements of cement production line most inferior coal or anthracite coal grinding fineness requirements.
  • compared with the same yield swept coal mill , saving 20 to 40%, especially in the case of raw water is large, saving even more sharply.
  • coal drying moisture up to 10% of the vertical grinder adopts air swept type operation, through the adjustment into the grinding wind gentle air, coal pulverizing and drying the moisture can be as high as 10%, with a great amount of wind to solve the high moisture drying requirements.
