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.
Product Introduction. The vertical roller mill has been widely used and promoted in the electric power, metallurgy, chemical industry, non-metal industry because the overall efficiency attributed to energy-saving and low consumption is becoming and evident in the cement industry.
Mill consistently uses five to ten percent less power than other cement vertical roller mills, and in comparison with traditional ball mill operations, the energy requirements for the OK cement mill is 30-45 percent lower for cement grinding and 40-50 percent lower for slag. The OK mill can contribute significantly to profitability and.
The industry best in energy-efficient grinding, the OK Mill uses five to ten percent less power than other vertical roller mills and 30 to 50 percent less energy than conventional ball mills. Easy operation and maintenance. Worn roller grinding surfaces can either be replaced or re-welded inside the vertical roller mill.
Under ideal working conditions, Raymond Mill consumes less energy than other ordinary grinding mills.
