A method for separating composite materials and mixtures, in particular solid-material mixtures and slags, and to a device for carrying out said method. The method for separating composite materials and mixtures comprises the step of transporting the composite material or the mixture through a separating device. The composite material to be separated or the mixture to be separated is excited by mechanical impulses as it passes through the separating device and is thereby separated. The device (1) for carrying out the method comprises a drive unit (21) for driving a rotor element (32), which is connected to a bearing/shaft unit (22) and which is part of a rotor unit (31). The rotor element itself has at least one rotor tool (33) and each rotor tool has at least one rotor tool component (34) and is surrounded by a stator element (42), which is part of a stator unit (41). The stator element itself has at least one stator tool (43) and each stator tool has at least one stator tool component (44). The rotor element and the stator element are substantially cylindrical.

20220242009 · 2022-08-04 ·

A method and system for recycling wind turbine blades. A scalper scalps off balsa wood and foam from recycled composite chips, a lump breaker shatters the chips produced by the scalper, a hammer mill breaks fiber chips produced by the lump breaker to reduce the chips to strand clusters, a vibratory screen and cyclone air classifier or circular vibratory screener separate strand clusters of acceptable size from larger strand clusters that require repeated processing with a hammer mill, another vibratory screen and cyclone air classifier or circular vibratory screener further separate strand clusters of acceptable size from larger strand clusters that require repeated processing with a hammer mill, and a granulator pulverizes the resulting fiber strand into micro-fibers that can be used as reinforcement fibers.

Method and Apparatus for Recycling Post-Consumer Plastic Waste
20210323198 · 2021-10-21 ·

A method of recycling post-consumer plastic waste into mono filament for use in fused filament fabrication, injection molding, or other plastic manufacturing processes. Contaminated curbside plastic waste is sorted and granulated to uniform sized flakes. The plastic regrind is cleaned in a closed-loop wash cycle and dried at 160° F. and −70 dew point to reduce the moisture content to less than 0.03%. The effluent water is purified to be reused in the system. The flake plastic is extruded to a molten state and passes through additional melt filtration. A laser micrometer measures extrudate metrics like diameter and ovality to dynamically control feed and flow rates of the extruder to maintain diameter uniformity within 0.018 mm of target diameter.

METHOD FOR SEPARATING THE LAYERS OF MULTILAYER PLASTICS

A system and method are for separating the layers of multilayer plastics, the fragments of multilayer plastic being carried into a receptacle (1) pressurized for 10 to 60 seconds. The receptacle is pressurized using overheated vapor generated in a boiler and introduced into the receptacle until reaching a pressure between 1 and 12 bar and a temperature between 100 and 191.12° C. The fragments are then carried to a discharge tank at a relative pressure between −0.7 and 0.1 bar and at a temperature between 15 and 25° C. for between 1 and 5 minutes. The multilayer fragments are later transferred to a mechanical separation unit where the fragments are separated into fragments of single-layer plastic and, lastly, to a mechanical sorting unit where the fragments are sorted by material.

METHOD FOR SEPARATING AND RECOVERING LAYERED FILM

A method for separating and recovering a layered film laminated and adhered with an adhesive, the method including a step 1 of immersing the layered film in a morpholine solution having a morpholine concentration of 50% by mass or more while stirring the layered film with heating at 20° C. to 90° C. or ultrasonically vibrating the layered film and a step 2 of recovering separated single-layered films that constitute the respective layers of the layered film. The adhesive is preferably a reactive adhesive containing a polyisocyanate composition and a polyol composition.
