Roller mills, bowl mills, or vertical roller mills offer size reduction of bulk materials in coal-fired power plants and cement works. In coal-fired power plants roller mills are used to grind coal, while in cement works they grind coal, raw meal and more recently, clinker. These mills offer a high throughput rate and high quality final product.

Cement Mill Reconditions Over a Dozen Coal Mill Rollers in Only 9 Days Working around the clock, seven days a week, a major cement mill located in the Mid-Atlantic region of the United States produces over 4,000 tons of cement each day.
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.
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.
