Abstract

Solid waste incinerator fuel is preclassified by passing it through a hollow rotating cylindrical drum which has two sets of extensions from the wall going lengthwise along the length of the drum, the first set toward one end and the second toward the other, the second set being shorter or smaller-sized than the first and the first preferably having rodlike projections which may have at least partly knifelike or bladelike ends or edges at the axial or inner ends thereof. The first set of extensions homogenizes the incoming waste by lifting, dropping, churning, and ripping it as well as fluffing it. The second set of extensions, preferably angled, lifts smaller sized heavier, non-combustible particles to the upper part of the drum from which they are removed at the exit end. The lighter material, mostly combustibles such as paper, textiles and wood, for example, is discharged toward the bottom of the exit end of the drum. When in operation the drum is preferably angled or tilted somewhat downward from entrance to exit end to facilitate movement of the material undergoing rotational treatment through the drum.
