Baum and Batac jigs the air pulsation types are more commonly used for coal cleaning because air pulsation provides better water pulsation control than mechanical type diaphragm used in Denver jig
Two types of jig Baum and Batac dominate the market and in the US they are supplied by 3 manufacturers Recent developments to improve the efficiency of operation are described McNally Pittsburg use 1 1/4 in fingers on multiple refuse gates on Baum jigs while Jeffrey Manufacturing install automated controls and use rotary sealed refuse
·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
·The characteristics of jig bivariate distributions are dealt in detail along with data reconciliation using the partition surface concept A method to combine the two stage circuit configurations with bivariate distributions and partition surfaces of the constituent separators is detailed The control of Batac jig is explained Finally a
·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
·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 bath or cyclone alternatives The principle of moving bed jigging is revived in the ROMJIG for the treatment of very large sizes De shaling at sizes
The main features of a Batac® Jig are • Water Only Process • Operating cut points from to • High Throughput Rates • Lump Ores 75 90 tph/m jig width • Fine Ores 68 78 tph/m jig width • Compact Design up to 7m in width • 1 or 2 cut points in one machine possible • Handle up to 20% feed and water variations
·The BATAC jig shown in Fig used a different configuration than the classic Baum jig in that the air chambers providing the pulsations were mounted directly under the bedplate The use of more sophisticated fast acting valves allowed much better control and optimization of the pulsation cycle By eliminating the U Tube configuration
·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
·The under bed pulsated BATAC jig has proved ideal for coarse applications from 150 mm down to fine coal in the 10 to 0 5 mm size range with throughput rates of between 100 and 1 200 tph MBE Minerals has also developed a reliable and economical solution in destoning raw coal the ROMJIG which has produced impressive results in extensive

·A modification of the Baum jig is the Batac jig which is used for cleaning fine coals The coal is stratified by bubbling air directly through the coal water refuse mixture in this cleaning unit Batac Jig technology has been installed in Kedla washery 2 no of jigs a course coal jig and a fine coal jig are under operation
·Dewatering of clean coal from coarse coal batac jig in dewatering screens capacity 70 TPH xiv Crushing of coarse middlings in the size range of 75 13 mm down to 13 mm in an impact crusher capacity 242 TPH xv Rewashing of crushed middlings in six cyclones 600 mm dia alongwith the mm middlings from small coal Batac jig to
·Among them the BATAC jig was developed by KHD in Germany and its application feedback is relatively good in both coal mining and non coal mining fields such as iron ore and gold mine Especially in Russia the BATAC jig is still favored to this day The maximum specification of the BATAC jig is 7m wide and long with a jigging area of
·Baum and Batac jigs—the air pulsation types—are more commonly used for coal cleaning because air pulsation provides better water pulsation control than mechanical type diaphragm used in Denver jig Fig 6 a [99 100] Furthermore Baum and Batac jigs are capable of over the screen and through the screen methods for the extraction of heavy
·Fig 7 and 8 show that for Sharshetali Batac Jig Ep and I rather steadily increase with the rise in cut density indicating poor separation At the same time though in an e rratic manner

Design and function MBE Coal & Mineral Technology USK Circular vibrating screen USL Linear vibrating screen and VSL High Frequency Screen with throughputs from 15 to 800 TPHare the result of our constant research and development based on many years of experience in the construction and manufacture of screening machines which allows our valued clients to
A batac jig is a variation of this design that uses an air chamber below the perforated plant to trap air and create the pulsing action Jig installations require specific conditions in order to be effective and are significantly less efficient than competitive heavy media processes As a result the use of jigs for coal cleaning has declined
