  • Pulverizer Wikipedia

    Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravity-fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table. Hot primary air for drying and coal transport enters the windbox plenum

  • Flow visualisation and velocity measurements in a vertical

    One method of controlling the particle size from a coal mill is the use of a vertical spindle mill static classifier, see Fig. 1.The vertical spindle mill static classifier resembles the well-known cyclone, except that it has a much shorter ‘barrel’ or cylindrical section, an inner pipe located on its central axis, a different path for the ‘rejected’ particles and an inlet flow which
