Coal Grinding Mill Classifier Design

  • Power Mills | Mill Technology | GE Steam Power

    For nearly 100 years—ever since pulverized coal combustion was adapted for power generation—GE has been a leader in coal mill technology for the power industry. That leadership continues today with the world's largest fleet of installed power milling equipment. Licenses for our milling technology can be found in all coal-powered regions

    classifier offers increased flexibility to take advantage of a wide (and sometimes lower quality) range of coal. For existing equipment, the DSVS classifier helps in low-NO X burner retrofits by providing higher fineness that reduces unburned carbon. Fineness levels can be adjusted by changing the classifier speed while the mill is on-line.
