Superfine Vertical Grinding Mill is very popular for coal ash grinding of its low energy consumption, environmental protection, and minimum noise. Superfine vertical mill is mainly used in the superfine mining fields of chemical industry, power plant desulfurization, non-metallic mineral processing.

KTMU vertical mills are used to grind coal, petroleum coke, anthracite and other explosive fuels. The equipment meets safety and operation requirements, e.g. instantaneous release of overpressure caused by an explosion of material. The mill releases exploded material away from the area of the grinding plant.

is employed for coal grinding mills and mills in the cement and industrial minerals industry. 2, 3, 4 or even 6 grinding roller con-figurations for a single grinding table can be realised. The first Type LM 26.3 D modular coal grinding mills were devel-oped in 1980 and employed for 12 times 2x600 MW power sta-
