Vertical coal mills are used for grinding bituminous coal, anthracite and petcoke for the burning systems in clinker burning and power generation according to the type and quantity of additives. Note: Raw coal size 40～50mm, feed moisture ≤15%, final product moisture ≤%, final product finenessR80μm=10%～12% (bituminous coal.
When it comes to grinding raw coal, savings in specific energy consumption can be achieved with vertical roller mills. Specific energy consumption depends on the grindability of the raw coal and the coal meal fineness required. A dynamic separator that ensures high separation efficiency also helps to reduce specific energy use.
