Wabash maintains the largest inventory of used & reconditioned Raymond mills in the United States. The Raymond brand is considered the gold standard for pulverizing coal and minerals.
2.2 Coal combustion. Pulverized coal combustion (PCC) is the most widely used technology for coal power generation. In this process, coal is milled, pulverized, and injected in the boiler with air to allow combustion. Combustion takes place at temperatures from 1300 to 1700 °C, depending largely on coal rank [17].
