Abstract

A system for melting metal scrap in a molten melting media comprises a housing having an upper portion wherein the melting media and scrap are brought together to initiate melting. The housing also has a lower portion in which a volute is located. An impeller, having a central hub, a circumferential band surrounding the hub, and canted vanes projecting radially from the hub to the band, is positioned in the lower portion of the housing to cooperate with the volute so that upon rotation of the impeller, metal scrap and melting media are moved downwardly and out of the housing.
