As a result of the higher ∆Pmill, the mill vibration increases. (8 10mm/s), which results in a good opportunity to test the effect of the grinding aid. In contrast to tests with ball mills, the effect of grinding aids in a VRM is already visible and audible after 10 20min. Table 1: Data used to produce Figure 3.
Ball mill, vertical roller mill and highpressure rollers can be considered to be mechanically reliable. The wear rate in g/t is higher in the ball mill than in the vertical mill or highpressure roller, but as the unit cost for wear parts is lower for the ball mill than for the vertical or highpressure mill, the total cost of wear parts is ...
