The VDM vertical bead mill series covers cylinder volumes of 2/50/200/1000/2500 L, batch capacities of 30–15000 L and motor power of 3/30/75/315 kW. Its wide model range suits both laboratory scale-up validation and full-scale production; the vertical design saves floor space and provides reliable media separation, mainly for ultra-hard and ultra-pure materials such as carbide and boride ceramic powders and oxide ceramic powders.
