AIR JIG. The Pneumatic process of beneficiation is the best suited option for Coals which has very high percentage of Near Gravity Material. This method involves size reduction and screening of coal to segregate it into defined sizes followed by concentration i.e. separation of particles into fractions more homogeneous in nature.

Performance analysis of jig for coal cleaning using 3D ...

Beneficiation studies were carried out on −4.76 + 3 mm sample, using laboratory jig with a screen aperture of 2 mm. The experiments were carried out at the parameter levels given in Table 2. The desired ash content in the clean coal was considered at 17%. Total height of the sample in the jig was maintained as 90 mm.

Beneficiation of Fine Coal Using the Air Table

Air table and air jigs were used to clean the coal. However, by 1985 the coal processing using these methods dramatically dropped to less than 7 million tons per year [5]. An excellent review on earlier dry cleaning processes is given by Symonds [6] and Donnelly [3]. In a pneumatic jig separator stratification is achieved through pulsating air ...

Batac Jig for Cleaning Fine and Coarse Coal Sizes

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 plunger-type air valves or rotary valves. The Batac jig uses flat discs which are electronically and pneumatically controlled.

Air Pulsated Jigs - 911 Metallurgist

Air Pulsated Jigs. An air-pulsated jig has teen widely adopted as a main coal washer. It may be mainly because of its many technical and economic features such as large capacity, low running cost, long life, etc. However, the recent increasing demand of fuel coal requires a higher productivity and efficiency of the air-pulsated jig.
