coal. It was possible to reduce the ash content from 24.32% in feed to an ash content of 16.55% in clean. coal at 2 L/min water flow rate and 10 min jigging time. Influence of operating ...
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 …
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. These upgrades breathed …

This chapter describes the mineral jig separator, its types, pulse forms, and the factors influencing its operation. Iron ore separation in a laboratory jig explains the procedure involved in the lab tests. The grade-yield-recovery calculations, from the layered samples and their assays, is discussed. A measure of the jig stratification index ...
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 of width size 5.0 m and also in ore and slag applications, where high energy input is required for the jigging process. disk valves are actuated by compressed air.
Batac jig is reported to treat both coarse- and fine-size coals satisfactorily (Chen, 1980) and has become an industry standard for coal cleaning (Zimmerman). Jig Feed In coal washing jigging is practiced on unsized material as coarse as 175 mm (7 in). In metal-milling practice jigging is now seldom employed on material coarser than 20 …
2009. The Coal and Minerals Technology subsidiary is acquired by McNally Bharat Engineering Company Ltd. (MBE) and renamed to "MBE Coal & Minerals Technology ". Based in Kolkata, India, McNally Bharat Engineering operates with approximately three thousand employees and boasts an annual turnover of around three hundred …
Experience gained in pilot plant operation of the separation techniques, over an extended period, was incorporated into the design of a 3 million tonne per year production plant. Jig chamber design, jig feed arrangements and the design of the plant flowsheet to achieve operational flexibility are discussed.
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 ...
A Batac jig of 300 tonnes per hour capacity was commissioned in the beneficiation plant. The jig capacity matches well with the overall plant throughput. Schematic layout of the materials handling system of the jigging plant is shown in Figure 3. This jig has primarily four operating parameters which can be optimised based on the feed ...
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 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 …

The principles of the Baum jig, Batac Jig, and the Pan-America Placer Jig are described. The chapter also describes the theory and operating characteristics of tables and single- and double-stage spirals. For places where there is a shortage of water, dry gravity separators are described. Notable features of various centrifugal gravity ...
However, recent theoretical calculations using Batac jig performance data indicate a Batac jig circuit that incorporates a heavy media cyclone rewash of the jig's middlings product can produce the same yield at a given quality specification. The jig also has a processing advantage over the heavy media cyclone circuit.
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 …
Batac jig shows an improved performance over that of the side pulsated Baum jig in terms of the spread of the pulse wave more uniformly over the entire deck area, even when the jig sizes are increased. The efficiency improvement is well recognized adjacent to the sidewalls of the jig, where the Baum jigs show poor performance. ...
The Denver jig is applied more for the separation of ores in mineral processing and only found limited application in coal cleaning. Baum and Batac jigs-the air pulsation types-are more commonly ...
First iron ore jig was installed in Barsua iron ore mine of SAIL. With the technology of bottom air pulsation added with modern process control features and improved product discharge mechanism, Batac jig of Humboltz Wedag have been successfully installed and operated at Noamundi iron ore mines of TISCO. ESSAR has successfully installed
At present the products of the MBE-CMT (Batac-Jig), All-mineral (ALLJIG) and Tenova (APIC-Jig) companies have big market shares as regards foreign water pulsatory jigs. The above mentioned jigs are used in beneficiation pro-cesses of coal and metal as feeds. In relation to the kind and parameters of the raw material to be beneficiated

The focus of present research is to see the efec-tiveness of Pilot scale Batac jig for beneficiation of coarse (− 13 + 1 mm) low volatile coking coal from Jharia through a …
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 ...
