To meet these demands, the entire grinding plant must be shock-resistant and have explosion relief valves.MAAG® GEAR WPU Gear Unit - Description Pulverization is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.Improving Coal Pulverizer Performance and Reliability - Pall Corporationاحصل على السعر
