Ball Mill Parameter Selection Calculation - Power ...

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media are the

Selective Mineral Jigs, 5 – 100 TPH Capacity Sepor, Inc

The jig cycle consists of an upstroke, or ‘propulsion stroke’, and a down stroke, or ‘suction stroke’. The upstroke results in the creation of a very ‘soft’ bed (dilation) where the lighter particles are lifted into the tailings stream and the heavier particles can readily sink and be sucked through the screen in the down stroke or the suction stroke.
