The pneumatic allair® jig offers many of the functions of the water-operated alljig®. However its dry process requires air as pulsating medium only.
Particularly for coal producers, the allair® represents a unique innovation with regard to productivity and quality. From hard and brown coal, the system generates marketable products at the lowest possible cost using a dry process. Thus, coal that could not be utilized previously due to its ash or sulfur content can now be efficiently processed using the allair®system. This results in a direct increase in economically exploitable reserves and therefore in economical use of natural resources.
