The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the separation process ...

The speed of the motion sideways and the interval of the knock can also be controlled. It is very important that water additions throughout the separation are such that the solids are kept in solution and that dry beds do not appear, thus hindering separation. Normally the deck starts in the horizontal with a hard fast knock and no side motion.
