Pulverizers Coal Grinding Roller Mills William''s Vertical Roller Mill Pulverizers utilize centrifugal force to grind coal material while maintaining low operating costs. Featuring easily replaceable wear parts, automated process controls and infinite turndown thanks to VFAC drives, these machines are perfect to use as a coal mill.

The ATOX® Coal Mill handles feed materials with less than one percent moisture and up to 25 percent moisture, where abrasiveness and stickiness is not an issue for grinding. Longlasting durability. The materials used to produce the ATOX® Coal Mill''s segmented wear surfaces are .

Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravityfed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.

For nearly 100 years—ever since pulverized coal combustion was adapted for power generation—GE has been a leader in coal mill technology for the power industry. That leadership continues today with the world''s largest fleet of installed power milling equipment.

The paper presents development and validation of coal mill model (including the action of classifier) to be used for improved coal mill control. The model is developed by using the mass and heat balance equations of the coal mill. Genetic Algorithm is used to estimate the unknown parameters that are used in the model validation.
