The difference between ball mill and vertical mill in cement grinding Over the last three decades the vertical roller mill has become the preferred ball mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system.

Vertical grinding does not have the metal impact of the ball in the ball mill colliding with each other and hitting the liner, so the noise is 20 to 25 dB lower than ball mill. In addition, the vertical mill uses a fully enclosed system, the system works under negative pressure, no dust, and the environment is clean.

races may rotate against a ball or roll (in a RingRoll Mill the rolls may rotate while the ring is stationary). RingRoll (BowlMill) and BallRace Mills comprise the majority of coal pulverizers currently in service at power generating facilities. Figure 3 shows a cutaway of a RingRoll type coal pulverizer. In this design the grinding rolls ...
