allmineral -allair®

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.

2019-7-5  The allair®-jig was invented for dry upgrading of coal. The advantages of jigging processes are combined with the advantages of dry beneficiation processes; e.g., no need for process water, clarified water or water purification, no fines dewatering, no slurry impoundment.

Coal Winnowing: An Innovative Technique for Dry

Thermal Power plants in India burn high ash content coal of 40-60 ash % due to the paucity of low ash coal. Combustion of high ash coals creates a lot of environmental issues like atmospheric pollution, generation of high quantities of fly/bottom ash, water and soil pollution. The common practice for reduction of mineral matter and undesirable pollutants in coal is by wet washing or cleaning.
