Dry sorting performed with the allair ® air jig increases the calorific value of the coal while achieving a significant reduction in the ash and sulphur content. The investment and operating costs are significantly lower than with wet processing as there is zero handling of water.

Completely dry working air-pulsed jig with high efficiency for the separation of different primary and secondary raw and waste materials. With throughput rates of 20 – 100 t/h per machine, the allair®-jig can process particle size ranges from 50 mm (2”) to less than 1 mm (16 mesh).

Jun 12, 2013 · In this study, -4 mm coal fines from Soma region of Turkey with the ash content of 31-32 % were treated through air jig employing the pulsation effect and the aerodynamic separators which...

Oct 16, 2018 · Traditionally in coal processing jigs have been used to clean the coarse coal fraction, the +3/8″ or +¼” material. Today with the advent of modern fine coal jigs in the United States, its place was moved from the coarse to the intermediate coal circuit, the 3/8″ x 100 mesh.

Applications: gravel, sand, coal, ore, salt, industrial minerals, broken stone, shredded material, non-ferrous metals, slag, construction waste, recycling materials; Throughputs ranging from 1 to 700 t/h; Grain sizes from 0.1 to 150 mm; Air-pulsed jig with rotary piston control or poppet valves

There are a number of advantages for upgrading coal with dry jigging technology, most notably the lack of process water, which eliminates the need for fines dewatering and slurry confinement. Dry jigging eliminates the product moisture penalty …

Test results of new dry coal separation methods e.g. new developed air jig and magnetic separator are reported. This article is supposed to give an overview of the research activities done at the Department of Mineral Processing, Technical University of RWTH Aachen, Gennany in …

Coal: Dry sorting performed with the allair® air jig increases the calorific value of the coal while achieving a significant reduction in the ash and sulphur content. The investment and operating costs are significantly lower than with wet processing as there is zero handling of water.

All-Air Jig: Density-Based Separation The All-Air Jig is a unit modified from the Stomp Jig. Coal is fluidized by a constant flow of air across a perforated table. Pulsating air provides the jigging action. Nuclear density gauge used to assist the control of reject rate. Units up to 100 tph are available. Raw Coal Pulsed Air Flow Constant Air ...

The allair® air jig for the beneficiation of coal and lignite in a dry environment without the use of water represents an absolute novelty with respect to specific capacities and performance. The product range has been supplemented by a wet high-intensity magnetic separator.
