However, jig washing technology has been subject to continuous improvement since the 1970s, and several improved jigs (e.g., the Batac jig and the Fisher Cails Babcock jig) have found wide application, particularly in Germany, India, and China. Much of the present R&D effort in this area is aimed at developing improved jig control …
Many existing washeries have BATAC ® jigs as the main washing equipment and this paper details the modifications carried out in them for reviving and improving their efficiency resulting in improvement of capacity utilization of such washeries which made CIL look into such renovations more seriously.
A pilot scale jigging studies were carried out using Batac jig with bottom screen of 1 mm aperture for the feed LVC coal of − 13 + 1 mm sized sample. About 100 kg of dry coal sample was used for each experiment to fill up the jig cham-ber. It was large scale batch process and its feed chamber contained five rectangular removable rings of 30 ...

If jigs are the intermediate size coal machine of the future, what is it like to operate them? Consol presently operates two Batac jigs: the Shoemaker jig which has been operating for 3-½ years and the Dents Run jig which has operated for one year.
rapid detection of changes in the raw material, quick reaction to such changes and easy operation of baTac Jigs provide the highest level of reliability in a vast variety of …
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 …
The jigs are 5000 millimeters (16.5 ft.) wide x 6200 millimeters (20.5 ft.) long with a jigging surface of 30 square meters (326 sq. ft.). The "Batac" jig is a 6 cell 2 compartment machine with the last cell in each compartment equipped with a feldspar bed to increase the cleaning efficiency of the finer particles.
The focus of present research is to see the effectiveness of Pilot scale Batac jig for beneficiation of coarse (− 13 + 1 mm) low volatile coking coal from Jharia through a series experimentation wherein appropriate diverse process parameters were exploited for definitive study. The feed coal properties were measured in terms of proximate and …
To achieve the ease of operation just described and to operate as efficiently as it does, the Batac jig has some very sophisticated controls. The unit also requires some operator adjustments to maintain …
JIG has also developed an inspection system whereby each facility is audited annually by a highly trained inspector. These inspections provide assurance that the facilities are operated in accordance with the JIG Standards and that fuel quality checks, equipment inspections and maintenance is carried out in line with the Standards, and that any ...
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.
Maintenance inspection is vital when it comes to the field service industry and help ensure that assets perform at their best.
A simulation method to assess the influence of feed and operational variables on the sensitivity of various two-stage circuit configurations is explained. The control of Batac jig is explained. Finally, a comment on the challenges ahead for improving the jig operations is given.

The under-bed pulsated Batac jig is shown to have improved performance over the Baum types. A comparative cost study showed substantial capital and operating cost advantages against dense medium ...
This paper describes laboratory and pilot plant testwork for the beneficiation of a medium grade iron ore, using gravity separation, by BATAC Jigs and wash waterless spirals. Factors leading to the selection of these methods of separation are discussed. Experience gained in pilot plant operation of the separation techniques, over an …
The % of NGM is therefore the primary criteria for choosing the correct separation process for small and coarse coal. For coals with simple or moderately difficult NGM levels, water-based processes such as Baum jigs, or advanced Jigs such as the Batac and Allmineral types, are suitable particularly to produce power station fuels (PSF).
The present communication examines size by size separation characteristics of a Batac jig cleaning metallurgical coal. The characteristics have been measured by …

The most important and also the most visible advantage of carrying out such a renovation work was that thorough maintenance of the antiquated BATAC®jigs was carried out.
Their adaptation to process coal established jigs as the most popular and efficient method of coal cleaning for over a century until the arrival of dense medium process. Increased demand for more and more cost-efficient methods of beneficiation lead to a review of the jigging process. Application of new concepts and the use of new …
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.
