Aug 01, 2015#0183;#32;However, in ball and tube mills, storage capacity for the coal is large and hence, speed of the feeders does not provide a good indication of the coal flow transported by the primary air to the furnace . The coal being supplied to the burners is related to the velocity of the primary air.
Perform mill dribble tests to determine minimum throat velocity amp; minimum PA flow. Perform mill response tests to evaluate proper balance of mill primary air/fuel ratio at high load. Implement additional correction to mill PA/Fuel Flow curve if necessary based upon mill response tests. Additional Program Components for Ball Tube Mills:
86 MILL DIRTY AIR FLOW TEST 861 Intoduction The factors affecting pulveriser performance include grindability of coal, moisture content of coal, size of input coal, wear condition of grinding elements and classifier, fineness of pulverized coal, primary air quantity and temperature On a daytoday basis, mill performance is monitored.

Nov 17, 2012#0183;#32; pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler burner
PulverizerWikipedia. Ball and tube mills. A ball mill is a pulverizer that consists of a Coalladen air passes through is controlled by regulating the primary airflow.
