Jig washer

A jig washer for coal or mineral separation usually works for relatively coarse material. The broken liberated ore, supported on a screen, is pulsed vertically in water; the heavy (valuable) portion passes through the screen into a conical receptacle (hutch), and the gangue goes over the side. In coal washing, the heavy (worthless) shale passes downwards, and the lighter coal remains on top.

Development of jig washer:

There are jig washers of different type: baum jig washer, mineral jig washer. For jig washer itself, there are jig washers with side driven device or up-down driven device, sine wave driven device or saw tooth wave driven device. Jig washer has a long development history from a single jigging hutch or chamber, double washing boxes, three jigging boxes, four jigging chambers, to eight jigging hutches. And there is also remarkable improvement about its operation from manual operation, to mechanical driven driven, and to hydraumatically driven.

Usage of jig washer:

Baum jig washer is mainly used in coal separation while mineral jig washer is mainly used for mineral beneficiation of gold, tin, iron, manganese, galena, antimony, copper, garnet, cinnabar, scheelite, wolframite, barite, fluorite and so on to gain high grade concentrate.

The jig washer will be improved in the future, even now it can deal with size of 0-50mm. This is the development of science and technology.
