The result is a power intensity that is higher than the low speed mills and overlaps that of the high speed mills. This allows the mill to be customized for a wide range of grinding applications.A case study at Aquarius Platinum's Kroondal Mine shows that the Knelson-Deswik technology can produce a consistent product size despite feed variations.

Bead Mill, Principle and Applications / Apex Mill series

Since the intensity of energy is determined by the mass and speed of beads, large beads with a high speed are needed for grinding large and/or hard particles. When grinding hard particles, such as silica, alumina, and hard natural ores, relatively large beads—larger than 0.3 mm—are used as a grinding

Speeding Up Your Organic Synthesis with Ball Mills

Figure 1 shows the operating principle of planetary ball mills, where rotation of grinding bowls mounted on a sun disc that rotates in the opposite direction accelerates grinding balls. Frictional forces are generated due to the resulting trajectories of the grinding balls, affecting processes between the grinding balls as well as between the wall of the grinding bowl and the balls.
