Abstract

A material Separator with a hopper, a rigid helically shaped tubular pipe structure, an inlet port, a large particle outlet port and a small particle outlet port. The helically shaped tubular pipe structure connected to the underside of the hopper. The helical pipe structure has an internal false bottom. The false bottom is perforated so that particles that are larger than the perforations flow down the upper portion of the helical tubular pipe structure and material particles that are smaller than the perforations drop through the perforations and flow down the lower portion of the helical tubular pipe structure. The larger material particles exit the large particle outlet and the smaller material particles exit the small particle outlet. A preferred embodiment includes the helical tubular pipe structure is constructed of a plurality of curved pipe members, each having flanges at each end so that one the flanged curved pipe member can be bolted to the adjoining flanged curved pipe member.
