pulverizers is ¾" to 1". Raw coal feed should never exceed 1¼", raw coal this size can plug throats and cause vibration. Raw coal that is too fine can plug the pulverizer or delivery components upstream of the pulverizer. Regular yard crusher inspection and maintenance is required to maintain optimum raw coal sizing. Mill FiresThe Ball mill pulveriser is basically horizontal cylindrical tube rotating at low speed on its axis, whose length is slightly more to its diameter. The inside of the Cylinder shell is fitted with heavy cast liners and is filled with cast or forged balls for grinding, to approximately 1/3 of the diameter. Raw coal to be ground is fed from the ...
