Jigs Coal Preparation. Traditionally in coal processing jigs have been used to clean the coarse coal fraction, the +3/8″ or +¼" material. Today with the advent of modern fine coal jigs in the United States, its place was moved from the coarse to the intermediate coal circuit, the 3/8″ x 100 mesh. Recent theoretical performance and ...

The Batac jig can treat coarse as well as fine sizes of coal. In other words, it can handle any of the sizes now being washed in the various types of Baum jigs installed in this country. The standard Baum jig uses either plungertype air valves or rotary valves. The Batac jig uses flat discs which are electronically and pneumatically controlled.

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.
