May 22, 2019 The larger the ball to material ratio, the higher the grinding efficiency. But too high a ball ratio is unhelpful. Because the amount of charge is reduced when the filling factor is constant, it is bound to reduce the productivity of the set, and sometimes reduce the alloy properties (Figure 8-2). The ball ratio is usually selected from 2:1 to 5:1.
