Coal mill. Capacity: 355t/h Applicable materials: Cement silicate products new building materials and etc. Application: Cement me tallurgy chemical industry and etc. Coal mill is the main equipment of pulverized coal preparation system which is mainly used for pulverizing coal with various hardness and also for pulverizing coal and ore in cement me tallurgy chemical industry and other industries.
Coal ball mill is the main equipment for grinding pulverized coal. The raw material of coal powder is coal with various hardness, and it drying in the coal mill grinding process to obtain finished coal powder which can be efficiently burned.
pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler burner panels.
