The operation of the mill-classifier system (Fig. 2) that was considered in this study is described in the following steps: the coal enters the pulverizer with 925 °C gas (1) withdrawn from the boiler. Then, the beater hammers (2) break the coal into smaller pieces, and the coal drying process begins.

The Raymond® Bowl Mill is considered the finest vertical roller mill available for pulverizing coal. The typical Raymond bowl mill system is designed to simultaneously dry, pulverize, and classify solid fuels to 95% passing 200 mesh (<5%R75μ) with a wide range of capacities from 24 to 150 stph.

A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer mill is used to pulverize coal for combustion in the steam-generating furnaces of fossil fuel power plants. Check now

Coal fineness above 300 μm was categorized as coarse, while coal fineness below 75 μm was categorized as fine coal powder. All pulverizers were able to classify more than 50% of fine coal. On the other side, pulverizer namely "B" had the highest coal fineness result of 77.78%, and Pulverizer D had the lowest coal fineness result of 51.96%.

of coal dust or air from the mill. Each mill is completely enclosed in an insulated sound-attenuating housing with panels that provide easy access to the mill. The mill is driven by a direct-coupled a.c. motor through a speed reducer and final single helical gear set having the driven gear mounted on the mill barrel.
