What is disclosed is a method of processing and/or recycling materials, especially thermoplastic materials,—wherein the material is agitated and mixed in a receivingvessel (), especially a cutting compressor or a preconditioning unit (PCU), and optionally also heated, comminuted and/or softened, wherein the material in the receiving vessel () remains in the form of pieces or particles and unmoltenthroughout, and—wherein the material in piece orparticle formbeing agitated within the receiving vessel is subjectedto inline spectroscopic and/or spectrometric analysis and/or measurement, wherein the measurements ascertained in this way are employed to obtain Information about the material being analysed in each case, especially quantitative and/or qualitative indices of the respective material. Likewise disclosed is an apparatus comprising—at least one receiving vessel (), especially a cutting compressor, having a mixing and/or comminuting device for the material,—at least one spectroscopic and/or spectrometric measuring apparatus () for inline analysis of portions of the material in piece of particle form being agitated within the receiving vessel (), which is designed to emit a physical Stimulus, especially electromagnetic radiation, for excitation of the rotating material in piece of particle form and—to detect the measurement Signals that arise in reaction to the Stimulus, especially characteristic spectra of the electromagnetic radiation scattered on the material analysed, preferably by spectrometric means, and—a Processing and control unit () which is in data communication with the measurement apparatus () and is designed—to actuate the measurement apparatus (), to emit the physical Stimulus, especially electromagnetic radiation, and to detect the resultant measurement Signals and to hold the measurements ascertained in this way available and—optionally, on the basis of the measurements ascertained, to derive and hold available Information concerning the material analysed in each case, especially quantitative and/or qualitative indices of the respective material.

Method and apparatus for processing and/or recycling of materials

Disclosed is an assembly for granulating polymer material, having a housing; a gas feed conduit having a rectangular cross-section and leading into the housing; a gas discharge conduit located downstream of the housing and having a rectangular cross-section; a granulating unit disposed in the housing and having a perforated plate feeding into the housing and a scraper, which comminutes the material emerging through openings of the perforated plate. In a plane running parallel to the plane of the perforated plate, the two lateral wall faces of the gas discharge conduit arranged perpendicularly to said plane enclose an angle αwith one another, and the two lateral wall faces of the gas feed conduit arranged perpendicularly to said plane or plane of section enclose an angle α, the two angles αand αbeing open towards the housing, and the angle αbeing larger than the angle α

Assembly for granulating extruded material

Disclosed is an arrangement for granulating polymer material, having a housing with a gas supply line, connected opposite the latter to the housing, having a rectangular cross-section, a granulating unit located at least partially in the housing and having a perforated plate of a feed or plasticising unit feeding into the housing, and a scraper which crushes or separates the material emerging through the recesses of the perforated plate, wherein in a plane running parallel to the plane of the perforated plate, the two lateral wall surfaces of the gas discharge line perpendicular to this plane include an angle α2 with one another, and the two lateral wall surfaces of the gas supply line perpendicular to this plane include an angle α1, wherein the two angles α1, α2 open towards the housing and wherein the angle α1 is greater than the angle α2.

Arrangement for granulating extruded material

Disclosed is a device for cooling particulate materials or particles, in particular granulates of polymeric materials, having an outer container with an, in particular frustoconical, outer shell surface and an inner container, which is arranged at least in sections in the interior of the outer container, with an, in particular frustoconical, inner shell surface, wherein an intermediate space is formed between the outer shell surface and the inner shell surface, wherein an inlet equipment for introducing a gas flow as well as the particles into the intermediate space is provided in an inlet-side initial region of the device, and wherein an outlet opening for the particles is provided in an outlet-side end region of the device opposite the inlet equipment, wherein the inlet equipment is so arranged and/or designed that the gas flow as well as the particles can be introduced substantially tangentially into the intermediate space.
