Abstract: A granulator which has a rotor knife seat having a plurality of tapped holes and a clamp to secure a knife to the rotor seat, is set forth. The granulator further includes a floor formed in the rotor seat and a trapezoidal shaped knife having a rear wall. The knife has an upper surface and a forward sloping surface, the sloping surface terminating at one end in a cutting edge and intersecting at its other end the upper surface and defining at said intersection a knife alignment edge. An adjustable clamp having a plurality of bolt holes is also provided. The clamp may be moved with reference to the rotor seat within the limits defined by the diameters of the bolt holes.

Abstract: An apron rack assembly for a granulator. The assembly includes upper crossmembers over which aprons are draped. The assembly is inserted into the hopper as an integral unit. The aprons are secured in place between the crossmembers and the roof of the hopper.

Abstract: A granulator knife having opposed reversible cutting edges. The knife is seated in a rotor or a bed and secured by a clamp. When the first knife edge is worn, the knife may be reversed. Adjustment of the knife position is not necessary.

Abstract: A bin inlet deflector for a granulator wherein the deflector is secured to the screen chamber and encloses the bin to ensure that all granulate is received in the bin and not outside the bin.

Abstract: There is disclosed in the present application an apparatus for sorting acceptable molded parts from material coming from a molding machine and requiring to be reprocessed or recycled. The present apparatus includes an auger formed with closely spaced flights in a receiving zone and more widely spaced flights in a transport zone in which scrap such as sprues, runners and defective molded parts are carried to a scrap discharge area. The acceptable articles, which have already been separated from the sprues and runners upon discharge from the mold, are of a size which allows them to pass between the closer flights of the receiving zone whereas the sprue and runner assemblies are carried by both the closer and more widely spaced flights to the scrap discharge area.

Abstract: A parts separator for separating small parts from a mixture with larger members, comprising a vertical cylindrical separator baffle wall and a continuously rotating conical rotor mounted co-axially in the baffle; the upper surface of the rotor is radially corrugated with the outer ends of the corrugation "valleys" large enough to accept the small parts but not the larger members. A mixture deposited on the rotor at an input location moves downwardly and outwardly, so that the small parts fall into the corrugation valleys and then through an annular gap between the rotor and the baffle onto a floor at the base of the separator; the small parts are pushed along the floor and out through a small parts discharge port. The larger members ride down the corrugation peaks and come out through a different discharge port, comprising a large gap in the baffle wall. A proximity switch monitors separator operation and affords an alarm in the event of interruption; a friction clutch affords specific overload protection.
