For example, grate discharge ball mills are efficient for coarse grinding, but not suitable for fine grinding. Overflow ball mills, on the other hand, are suitable for both coarse and fine grinding but require a higher level of maintenance.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

This means that when the sun wheel rotates once, the grinding jars rotate twice in the opposite direction. Figure 4. In the planetary ball mill, centrifugal and Coriolis forces permit grindings down to the submicron range. The result of grinding of alumina (Al 2 O 3) at 650 min -1 in the PM 100 is shown in Figure 5.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
The Planetary Ball Mill PM 100 is a powerful benchtop model with a single grinding station and an easy-to-use counterweight which compensates masses up to 8 kg. It allows for grinding up to 220 ml sample material per batch. The extremely high centrifugal forces of Planetary Ball Mills result in very high pulverization energy and therefore short ...
