AMERICAN KUHNE CORP.

Complete recycling systems from Kuhne Anlagenbau GmbH sort, wash, filter, and extrude 100% recycled film or sheet in a one-step process.

AUSTRONIC INSTRUMENTS BLOWMOULDING TECHNOLOGIES INC.

Indumat recycling system for film, tape, monofilaments, bags, etc. A shredder, which preheats the material while cutting it into small pieces, is linked directly to the extruder. Preheating material saves half the horsepower in subsequent extrusion. Coarse filter ahead of the double slide-plate fine filter in the extruder removes large contaminants and thus prolongs life of fine filter. Hot die-face or strand pelletizing completes the process. Outputs to 2500 lb/hr.

BARRON INC.

Options available for re-introduction of roll and loose scrap. Refeed rates to 1200 lb/hr on extruders from 2.5- to S-in. diam. Refeed machines can be mounted on extruder throat including round, square or oblong feed-throats.

Inline film-trim repelletizing systems including dual-diam. extruder/pelltizer for extrusion applications that require uniform, high-bulk-density repro or are reclaiming high percentages of scrap. Operable with materials such as LDPE, HDPE, PP, PS, ABS and coextruded blends at rates to 500 lb/hr. Scrap can be re-introduced accurately via gravimetric blenders. Other features include air- or water-cooled pelletizing, modular design with small footprint, and low noise level.

Plant scrap repelletizing systems for postindustrial scrap recovers costly roll scrap, cut-outs and other waste and reduces size of scrap to manageable inventory. Provides granules with minimum polymer degradation and no contaminants. Allows scrap to be accurately re-introduced into primary process with gravimetric blender. Can repelletize films with print levels up to 25%. Output rates to 1500 lb/hr.
