    Large Ball Mill Scale

    A ball mill is a large cylindrical tube partially filled with steel balls. The ends of the steel cylinder are attached to trunnions that are supported on journal bearings. As the ball mill rotates, the steel balls in the cylinder rise up on the mill's inside surface and eventually tumble down to the bottom. The raw material is fed into the ball.BALL MILL DRIVES, LOADED, PEAKVUE LEVELS, SEPTEMBER 1A 1B • Above is a plot of the high frequency Peakvue levels at both the 1A 1B ball mills when loaded. • Like the earlier HFD levels, note how the Peakvue levels at 1A ball mill coupling end pillow block bearing (PIK) are much higher than that at 1B ball mill.
