industry use of coal mill reject. Air entering through the Port Ring creates a fluidising zone in which 'heavy material' Mill Rejects such as rock falls through the Port Ring into the Air Plenum below the Grinding Table and is ejected from the Mill through the Mill Reject System • Drying of the coal occurs through contact with the heated air and surfaces within the mill •

Coal from travelling belt of raw coal feeder drops in central feed pipe ( connection between Raw Coal Feeder and Mill). After coal reaches Mill bowl grinding started and hot air also been given to make the pulverised fuel dried enough to classifier chamber. The portion of the coal which cannot be grinded finds its way to mill reject.

Step 3: Flow Rates of Feed, Overflow (Clean Coal) and Underflow (Reject) The volumetric rate of solids in each process stream, which excludes medium, can be determined by relating mass flow to the DMC units to the average density of each stream. w is the fractional content of feed in the given size fraction and Ñ„ the fractional surface ...

An overwhelming majority of coal fired boilers utilize a pulverized coal firing system. These systems utilize a pulverizer or mill to grind coal to a desired fineness and subsequently transport the coal to the burners using air as a transport medium. Air utilized to transport coal to the burners is considered "Primary Air".
