Abstract
An air classifier system which embodies two rotary drum classifiers, each with an individual adjustable plenum, the drums being individually angled at selected inclinations and the plenum capacities being variable, so that two separate masses of commingled materials such as municipal refuse and oversize bulky waste, for example, may be simultaneously classified and will produce a combined single output of refuse derived fuel.
