Inclined helical flight conveyor
First Claim
1. A helical conveyer comprising a container having an inlet for mixture at one end, an outlet for liquid at the same end, and an outlet for particulate material at the other end, a shaft rotatably mounted in the casing coaxially therewith, a helical flight fixed to the shaft between the shaft and the casing, said flight comprising a series of circular rings cut radially and pressed into helical shape, each ring being welded to the shaft at a plurality of arcs on the inner edge of the ring, said ring having openings therein between the arcs, the diameter of the shaft being 0.3 to 0.55 of the outer diameter of the ring, the radius of the openings from the centre of the ring being 1.2 to 1.6 times the radius of the shaft, said rings being unconnected with the shaft at said openings.
