brakes of balls in coal mill

  • COAL BASED THERMAL POWER PLANTS COAL MILLS FOR

     · Normally the ball mill designers use three types of balls with three different diameters. These balls reduce in size as the mills operate and so the highest size ball is normally used for recharging. In earlier days most of the ball mills had a single inlet and outlet but now designers use both ends to feed coal and also for taking out pulverized coal.
