Individual large air swept Vertical Mills are preferred over ball mills for better grinding efficiency and to get an advantage in power consumption. Cement raw material is the mixture of mainly Limestone & other constituent such Iron oxide, Shale etc. having different moisture contain depending on composition & deposit.
Raw mill is mainly used for grinding cement raw meal in the cement factory production process. It is also suitable for metallurgical, chemical, electric power and other industrial mining enterprises to grind various ores and other grindable materials. Cement raw meal is a mixture of various raw materials before cement calcination.
Cement vertical mill, also called roller mill, is another raw mill commonly used in cement plants. Compared with the cement ball mill, it has a great difference in structure, grinding principle, process layout, automatic control, and energy consumption, which play an important role in the modern cement industry. High Grinding Efficiency.

LM Vertical Grinding Mill Working Principle. The grinding plate rotates under the action of main motor of LM Vertical Grinding Mill and the reducer. Meanwhile, hot wind enters the vertical mill. After raw materials fall onto the center of grinding plate, they move to the edge of grinding plate under the action of centrifugal force.
This work concentrates on the energy consumption and grinding energy efficiency of a laboratory vertical roller mill (VRM) under various operating parameters. For design of experiments (DOE), the response surface method (RSM) was employed with the VRM experiments to systematically investigate the influence of operating parameters on …

During heat up there should be a sufficient air flow through the mill to force the heat transfer to the grinding part – forced convection. A sufficient air flow will result in a mill differential pressure of> 5mbar. The duration of heating should be at least until the temperatures after mill and after bag filter reach 85° C.
When the system air volume is too large, the internal pressure difference decreases, the main motor current decreases; the thickness of the material layer is too low, the vibration value is large, and the sieve residue increases. ... When the raw material is running in the vertical mill, the drying heat source of the material comes from the hot ...
