Abstract
The present invention relates to a rotary lump crusher/reclaiming drum for reclaiming lump materials such as aggregates, chemically-bonded sand lumps, dross, ferrous and non-ferrous scrap and slag. The rotary drum has an outer cylinder concentric with an inner cylinder both of which rotate simultaneously, the latter containing treatment compartments to reduce the lumps to smaller pieces which are in turn reduced to reclassifiable particulate matter in preparation for resuage.
