Fineness And Moisture Regulation Of Coal Mill Vertical Mill

The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates. In extreme cases, the performance of the boiler may be limited, and therefore improving the fineness of milling

    The vertical mill can dry the material with 12%-15% moisture, and the drying ability is strong. Even if the ball mill is dried, only the material with moisture content of 3%-4% can be dried. . Therefore, vertical mills are used for the production of materials with large moisture content, which not only saves economic costs, but also saves time
