    A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills..within the unit to crush the coal sample. The coal fines are sorted and the quantity of coal less than a specified size is recorded and converted into a Hardgrove Grindability index HGI value. The HGI value is used by utilities to evaluate how coals will perform in their mills this includes grinding power requirements and throughput capacities.
