The water- and air-pulsed alljig is a smart, reliable and economical solution best suited for materials such as sand, coal, iron ore, salt, industrial minerals and recycling materials.
2. Mechanical concentration (Placer Deposits) • Mechanical concentration is the natural gravity separation of heavy from light mineral by means of moving water or air by which the heavier mineral become concentrated into deposits called placer deposite. • It involve two stages:- 1. The freeing by the weathering of the stable mineral from their matrix.
Nowadays, dry beneficiation technologies with an air dense medium fluidized bed come into prominence in the field of coal preparation. In this study, the optimum conditions for different operational parameters such as discharge stargate rate, pulsation frequency, and superficial air velocity were investigated on separation of semi bituminous coal from Soma (Imbat) region …

alljig® jigging machines are air-pulsed, and therefore the pulsation of the water may be achieved nearly wear-free and so the stroke-motion (frequency, amplitude and shape) can be adjusted …
Beneficiation of indian iron ore lumps and fines by using underbed air pulsated BATAC jigs
Diaphragm jig is a type of jigging machine that is widely used in gravity separation plants, whose working principle is to drive the diaphragm by eccentric connecting rod, cam lever or hydraulic device causing reciprocating motion. Based on the diaphragm installation position, diaphragm jigs can be divided into top-moving (si…
The air forces the water in the air chamber down, creating the pulse on the ore bed, and lets the air out to allow the ore bed to settle on the jig screen deck before the next pulse begins. The …
Air-jigging machines for separation without water | allair® The allair® jig comprises many of the features of the alljig® wet jigging machine, but operates with air only. Developed specifically with coal producers in mind, the allair® is a milestone in productivity and quality, producing marketable fuels from coal at minimum cost.

The mixture of water and ore particles is fed from the end onto the sieve plate of jigging chamber. The ore particles move under the action of vertical alternate water flow and ...
When jigging, the amount of water added under the screen is required to be sufficient, and the amount of water should be kept constant. For general metal ore beneficiation, the water volume is 5~10 meters per ton of ore, and the water pressure is required to be greater than 2 kg/cm. #3 Bed Properties and Composition
manganese ore. Description of air-pulsed jigs Detailed descriptions of the features of the various air-pulsed jig designs can be obtained from vendors. However, the fundamental principle of air-pulsed jigging is the injection of low-pressure air (<1 bar) into a chamber with an open base, to accelerate the water column through the bed of ...
Like the water jig, it consists of an inclined sieve, over which the crushed ore is passed, and through which the air is blown into the ore. The air current is intermittent, and being proportioned in strength to the thickness of the ore bed, the latter is lifted bodily, and falls again upon the sieve a great number of times during its passage ...
Dry jigging (also called "pneumatic" or "air jigging", though these designations may be mistaken as air-pulsated water jigs) is becoming more and more relevant as the concern with slurry waste disposal and water handling costs intensifies.
