An installation (1) and method for treating composite products (2) based on thermoplastic material(s) for recycling purposes, the installation at least comprising means (3, 4, 4′, 5, 6) for heating, for reducing size, for crushing and for separating, said means being arranged to form at least one line (1′) for treating and extracting material(s) to be reused, operating as a continuous or intermittent flow, and regulated if necessary. The installation (1) is characterised in that the means (3) for heating and reducing size comprise at least one heated screw mixer, the crushing means comprise at least one roll crusher (4, 4′) comprising two rolling rollers (7 and 7′) that are heated and set into rotation in opposite directions, the separating means (5, 6) comprise at least one macroscopic separating means (5) in the form of a device for discharging macroscopic polluting particles present in the output (3′), and the separating

The invention relates to a mechanochemical process for decontaminating and/or for eliminating problematic, synthetic, biogenic and biological materials A; for breaking down phosphates B; for immobilising metals and the compounds C thereof; for separating carbon dioxide and carbon monoxide D into elements; and for recovering valuable products E. The process comprises: —providing a material F to be milled containing —at least one material A, B, C and/or D and —at least one type of carbon or carbon-yielding material G, or alternatively providing the components of F and G separately from one another; —filling the material F to be milled into a mechanical mill (1), or alternatively —filling the components of the material F to be milled into a mechanical mill (1) and —milling by means of milling elements (1.2) moved by agitation means (1.4) or by means of rollers (1.4.6); after which —the resulting product I is separated from the milling elements (1.2) or the rollers (1.4.6) and is discharged from the milling chamber (1.1) and worked up. The invention also relates to the use of the products I as valuable materials E, the use of a self-cooling electric motor (4) for driving a mechanochemical mill (1), and mechanochemical mills (1) having new agitation means (1.4).

The invention discloses a device for recycling waste tires, which includes a machine body. The upper end of the machine body is provided with an inlet with an upward opening on the right side of the body. The left wall of the inlet is connected with a chute. The chute is provided with A steel wire removal device, a crushing cavity is connected to the lower wall of the inlet, and a crushing device is fixed in the crushing cavity. A twisting cavity is provided in the left wall of the crushing cavity and below the chute. A fourth motor is fixed in the wall, and an eccentric wheel is dynamically connected to the lower end of the fourth motor. The invention can quickly and accurately pull out the steel wire layer in the tire and twist the broken rubber stuck on the steel wire, so that the steel wire and the tire are cleaned. Recyclable materials such as rubber are separated. At the same time, the tires that have been torn out of the steel wire are broken into small pieces of rubber, which is convenient for the next processing, which not only saves the company a lot of material costs, but also saves a lot of time costs and labor.

An apparatus for the production of items of clothing, which includes at least one shredder, at least one pulverizer, at least one mixer for the mixing of the powder that originates from the pulverizer with at least one other substance chosen preferably from a solvent, polyethylene glycol, and a polyether and organic binders, with consequent obtainment of a mixture. The apparatus also includes at least one extruder of the mixture, which is arranged on a movement unit with at least two axes, for the deposition of layers of the mixture on a predefined surface, with consequent provision of at least one portion of an item of clothing and the like according to a method of the type of additive manufacturing.

A method for obtaining recyclate from thermosetting materials, comprising the following method steps: providing thermosetting starting materials to be recycled; breaking the thermosetting starting materials with a twin-shaft shredder to obtain a plurality of fragments; shredding the fragments with a single-shaft shredder to obtain a plurality of flakes; and fine grinding of the flakes with a grinding device to obtain a recyclate powder.
