The Loesche coal grinding mill range is divided into two serial types: Small twin mills constructed to individual specifications (LM 12.2 D to LM 20.2 D), with table diameters from 1,200 to 2,000 mm. Larger mills with two, three and four rollers and modular struc-tures (LM 21.2 D to LM 43.4 D), with table diameters from 2,100 to 4,300 mm.
Vertical Roller Mill The vertical roller mill (VRM) shown in Figure 4 is an air swept, medium-speed, vertical pulverizer with integral classifier.

To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
Coal Vertical Roller Mill (VRM) is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grinding roller onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness.

Mill Tailings. Ore or mineral milling or concentration can be performed by a number of methods, such as gravity concentration, magnetic separation, electrostatic separation, flotation, and leaching. The object, in each case, is to separate the metal from the less valuable matrix rock, or gangue.
Coal mill employed at coal fired power plant. In coal fired energy plant, coal mill is employed to grind, pulverize and dry coal ahead of the coal is transmitted the boiler. The coal is feed into the coal mill by way of a inlet pipe so that the roller coal mill such as Raymond mill and vertical mill can pulverize the coal into particles.

The coal is charged inside the melter gasifier, so even non-coking coal can be used, which makes a coking plant unnecessary. The high dome temperature exceeds 1,000°C, resulting in cracking of the coal's relieved hydrocarbons and avoiding the formation of tar. The cost of Corex coal is approximately 40% lower than for coal used in blast ...
