Patent number: 5143308Abstract: Apparatus and process for recycling post-consumer plastic containers supplied as compressed bales thereof to recover at least uncolored and colored PET uncolored and colored HDPE in flake form is provided. The apparatus and process includes debaling, sortation of the desired containers from the bale, granulation of these containers into flakes, wet processing to dissolve glue and the residue of contents of the containers and to provide separation of contaminants from the desired flake by specific gravity difference, and recovery of the purified flakes.Type: GrantFiled: March 26, 1991Date of Patent: September 1, 1992Assignee: Plastic Recycling Alliance, LPInventors: Nazim S. Hally, Eric J. Koelsch, Joseph M. Shields, Jr.

Patent number: 5139203Abstract: Scrap goods (S), for example, electronic and electrical apparatus, components, cables and the like are intermittently and alternately mechanically crushed (1,3), magnetically separated (2) and mechanically-physically separated, for example, by means of electrostatic separators (5, 10-12). With the crushing, the dust produced is pneumatically gathered and filtered out (22,9). A non-metal fraction (A) as well as a magnetic (B) and non-magnetic fraction (C) are produced separately as granules and dust. The metal fractions (B, C) are suitable for further pyrolysis-free, wet chemistry and/or electrolytic separation. The non-metallic fraction is capable of being precipitated. The method is noted for its minimal energy consumption and high environmental compatibility.Type: GrantFiled: January 31, 1990Date of Patent: August 18, 1992Inventor: Kamal Alavi

Patent number: 5110056Abstract: The invention relates to a method and a grinding plant for reduction of brittle material for grinding, in which material which has undergone primary reduction from a first grinding stage is delivered as fresh material to the second mill of a second grinding stage and finished product is removed from this second grinding stage, and in which the quantity of feed material of this second mill is kept constant when the quantity of finished product alters by altering the quantity of fresh material. This first grinding stage contains an air separator from which the fines are fed as fresh material to the second mill. In the event of alteration in the quantity of fresh material for the second grinding stage the quantity is kept constant by corresponding alteration of the fineness of separation of the separator of the first grinding stage.Type: GrantFiled: February 8, 1991Date of Patent: May 5, 1992Assignee: Krupp Polysius AGInventors: Gotthardt Blasczyk, Norbert Patzelt

Patent number: 5096128Abstract: A grinding device for medical waste includes a driving device, a hollow housing, a shaft vertically journalled in the housing driven by the driving device. A first bowl-shaped grinding container is coaxially provided in the housing with respect to the shaft, and includes a first wall having a plurality of through holes. A first cutting blade extends radially inward from the first wall. A second cutting blade is transversely provided above the first cutting blade and is adjustably mounted on the housing. The second cutting blade is cooperatively associated with the first cutting blade. A second bowl-shaped grinding container is coaxially provided in the housing, with respective to the shaft, around the first grinding container. The second grinding container has a second wall with a plurality of through holes. A third cutting blade extends downward from a radial inward flange on the second wall.Type: GrantFiled: February 19, 1991Date of Patent: March 17, 1992Inventor: Wu-Shun Chang
