 · Vertical Mill design also plays a factor; namely the orientation or position of the grinding elements relative to the throat vanes and the pulverised coal and primary air (PA) velocity vectors. The table is generally positioned at or below the centreline of the PA throat vanes thus the primary wear mechanism on the table is from compression and the sliding friction of the coal across the table.

The pulverised fuel continues its journey towards the coal burners for combustion. The coarse particles rejected in the classifier are returned to the mill for another cycle of grinding. In order to avoid excess sweeping of coal from the mill, only part of the primary air, directly proportional to the boiler load demand, is passed through the mill. Furthermore, to ensure sufficient velocity of ...
