Abstract
Solid waste incinerator fuel is preclassified by passing it through a hollow rotating cylindrical drum which has magnetic extensions called flights protruding from the inside of the drum wall along its length. The drum may also have a first set of non-magnetic flights toward one end protruding farther from the wall toward the center or axis of the drum then a second non-magnetic portion on the other side of the magnetic flights along the length of the drum. The magnetic flights attract particles and material subject to magnetic attraction. The ends of the first set of non-magnetic flights toward the middle of the length of the drum are preferably shaped or rounded somewhat lengthwise. A scraper assembly preferably having two material removal channels or chutes in addition to a scraper blade, may be arranged to extend into an exit end of the drum. The scraper blade removes magnetic or iron particles from the magnetic flights as the drum rotates. These are carried out of the drum via a first of the two channels, with the non-magnetic noncombustibles being carried out via a second.
