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.

An introduction to dry powder classification

2018-2-1  A dynamic air classifier can classify a wide range of materials with particle sizes from 3 to 100 microns and can operate either inline or offline, depending on the process. A dynamic air classifier can achieve high production yields and efficiencies, using either pneumatic or gravity conveying to feed material into the system at load factors up to 2 kilograms of material for every kilogram of air.
