Vertical Spindle Mills The vertical spindle mill is a medium speed pulverizer and maintains a considerable amount of fuel in the mill system when operating. Coal collects on the grinding table, in the classifier, in the pyrite collection sec- tion below the grinding table,.Level and leads to increased fuel and ash handling cost and possible deterioration in ESP collection efficiency. In a typical vertical spindle pulverizer (Figure 1), raw coal is fed through a central coal pipe at the top of the pulverizer and falls by gravity to the rotating grinding table, mixing with classifier rejects returned for re-grinding.
Vertical roller mill is mainly used for grinding raw meal, clinker, Ground Granulated Blast Furnace Slag, iron ore, limestone, coal powder, coke Bed Mill A bed mill, on the other hand, moves the material perpendicular to the axis.The bed of the mill moves along the Y and Z axes and the spindle moves along the X-axis, providing a full, 3.The MPS 150 mill is classified as an air-swept, pressurized, applied-force, vertical spindle, table roller mill. It contains an integral classifier, a grinding section, a base section, and auxiliary com- ponents (See Figure 4). In the grinding section, three fixed-axis rollers rotate on a segmentally-lined grinding table sup-.
