This technology is air-pulsed jig which is best suited for areas where water is scarce and also where customers are particularly interested in keeping water contamination to a minimum. Since it uses no water and processes solely using air, it has a distinct advantage of not adding an undesirable increase in moisture content which is normally associated with wet processes. Typically in a Sponge Iron unit where minimum moisture addition is sought in the clean coal and the rejects could be used in the power generation through AFBC boilers, this jigging machine would be preferred by customers. To add to these features its fully automatic operation with analog measurement of bed depth, low capital investment and low operating costs makes Allair a vary interesting proposition for the customers.

Governments all over the world are continuing to place even more stringent limits on the release of pollutants and thus Allair enjoys the principal advantage of being environmental friendly and offering a dry processing system with a quantum improvement in separating efficiency without introducing a moisture penalty to the clean coal product.
