The hutch is a Ushaped tank. This jig is widely used in the field of coal beneficiation. As the device becomes larger, it becomes difficult to generate a uniform pulse across the jig width, which limits the jig size. The variwave jig is a type of Baum jig that uses a trapezoidal waveform to separate the particles, instead of the sinusoidal ...

Jigging is a densityseparation process which is widely used to separate heavier particles from the lighter ones. It is used for beneficiation of ore minerals as well as washing of coal. In its class it is by far the simplest yet a robust mechanical device that can treat comparatively larger size feed materials at higher throughputs.
