Jig washing systems can treat both large and small coal in a single unit. Over the years, jig washers have shown a significantly improved performance, particularly in cleaning small coal. One of the most notable developments in this area has been the Batac jig, which in some forms, is claimed to be capable of washing coal down to 3 mm.
It should be noted that the jigs were originally designed to process ½" x 0 raw coal, however, our deteriorating ROM product required a change to ¾" x 0.

The Batac jig is a newly-designed Baum-type jig for coal washing. Multiple air changes directly under the bed permit uniform distribution of air pulsations, giving greater capacity and more accurate separation than standard Baum jigs. It is equipped with a new concept of air valves, automatically and electrically controlled, permitting infinite variation in jigging …
Figure 1 shows a typical curve fit, for an overall (2-stage) separation using a Batac jig with a 1/2 by 3/8-inch size fraction. Table I indicates that the standard deviation is 8.54 X 10-3 in this case. Figure 2 shows another fit, for a Dynawhirlpool with a 14 by 28 mesh size fraction. Notice the difficulty in fitting the upper "shoulder" of ...
MBE Coal and Mineral Technology Pvt. Ltd. (formerly Humboldt Wedag- Coal and Mineral Division), took up the task of reviving these antiquated BATAC®jigs by refurbishing the controls, changing the me- chanical parts etc. in order to make them ready for the present coal characteristics. This improved the efficiency of the jig and also reduced ...

Batac jigs (originally called TACUB (Takakuwa air chamber under bed) jig), the air chambers (single or multiple but, usually 2 cells) are positioned under the separation chamber (Fig. 6c).
BATAC jig and spiral separator iron on beneflciation plant 423 During the test programme, it was apparent that a middlings and a final reject product from both the lump and the fines jigs would be possible, and this option was tested by passing the reject back through the jig for a second pass to simulate a third stage of jigging. Typical test ...

Baum and Batac jigs are two types of air-pulsated jigs, which have found extensive applications in the coal industry. Stratification of particles in a Baum jig is caused due to the effect of pressurized air into the jig water system, which in turn causes alternate pulsation and suction of coal particles fed over the ragging bed.
