An apparatus includes first and second conveyor structures with first and second conveyor surfaces. The conveyor surfaces face each other and are arranged to define a comminuting space in the apparatus. The apparatus brings the conveyor surfaces in movement in the direction from a first end of the conveyor structures towards a second end of the conveyor structures, and the two conveyor surfaces are placed to face each other. The conveyor surfaces are additionally placed in a convergent manner so that the gap between the conveyor surfaces narrows in the movement direction of the conveyor surfaces. The advancing movement of the conveyor surfaces brings about compression in material being comminuted. The conveyor surfaces are in a double-converging so that in addition to the convergence in the movement direction, the conveyor surfaces are additionally convergent in the transverse direction in relation to the movement direction, the comminuting space thus also being double-converging.

Provided are a shredder assuring greater freedom in designing a feedstock supplier that supplies sheets, and a sheet manufacturing apparatus. The shredder has a feedstock supplier having a supply opening through which a sheet is supplied; and a shredding device configured to shred the sheet supplied from the feedstock supplier. The shredding device includes a rotary cutter that rotates on a first axis, and a circulating cutter that moves in an endless path and cuts the sheet in conjunction with the rotary cutter. The circulating cutter includes a conveyor configured to convey the sheet from the feedstock supplier to the rotary cutter.

The invention relates to an apparatus for comminuting of material. The apparatus includes a first conveyor structure with a first conveyor surface, a second conveyor structure with a second conveyor surface, and in which apparatus the first conveyor surface and the second conveyor surface are set facing each other. The conveyor surfaces are arranged to define a comminuting space in the apparatus, The apparatus has means for bringing the conveyor surfaces in a movement in the direction of movement D where the two conveyor surfaces placed to face each other are arranged to move from a first end of the conveyor structures towards a second end of the conveyor structures. The conveyor surfaces positioned to face each other are placed in a convergent manner so that the gap between the conveyor surfaces narrows when examined in the movement direction of the conveyor surfaces, so that the advancing movement of the conveyor surfaces is arranged to bring about compression in the material being comminuted. In the invention, the conveyor surfaces are in a double-converging manner so that in addition to said convergence in the movement direction, the conveyor surfaces are additionally placed in a convergent manner so that the gap between the conveyor surfaces also narrows in the transverse direction in relation to the movement direction, said comminuting space thus becoming double-converging.

An apparatus for disposal of electronic devices includes a transport mechanism for transferring the storage devices through the apparatus. A scanner scans or reads the devices as the devices move through the apparatus, a sanitizer for degaussing or erasing the storage devices, and a destruction mechanism for physically deforming the devices. The apparatus is further configured to receive scanned information from the scanner, determine identification information for the devices based on the scanned information, and update status information of the devices during movement of the devices between the scanner, sanitizer, and destruction mechanism.

A method and apparatus for recovering fibres from fibre reinforced polymer (FRP) materials uses a thermomechanical process to produce high quality recovered fibres and powdered polymer resin. The thermo- (cryo-) mechanical process uses a combination of a selected range of temperatures and mechanical force, and is chemical and solvent-free, and produces zero waste. Fibre length remains unchanged after processing and mechanical properties of the recovered fibres are comparable to or better than those of virgin fibres. The recovered fibres and powdered polymer resin may be used to make new FRP products.

The invention relates to an apparatus for comminuting of material The apparatus comprises a first conveyor structure (CI) with a first conveyor surface (B1), a second conveyor structure (C2) with a second conveyor surface, and in which apparatus the first conveyor surface (B1) and the second conveyor surface (B2) are set facing each other. The conveyor surfaces (B1, B2) are arranged to define a comminuting space (GS) in the apparatus, The apparatus has means (MIA, M2A) for bringing the conveyor surfaces in a movement in the direction of movement D where the two conveyor surfaces (B1, B2) placed to face each other are arranged to move from a first end (E1) of the conveyor structures towards a second end (E2) of the conveyor structures. The conveyor surfaces positioned to face each other are placed in a convergent manner so that the gap between the conveyor surfaces (B1, B2) narrows when examined in the movement direction (D) of the conveyor surfaces, so that the advancing movement of the conveyor surfaces is arranged to bring about compression in the material being comminuted. In the invention, the conveyor surfaces (B1, B2) are in a double-converging manner so that in addition to said convergence in the movement direction, the conveyor surfaces are additionally placed in a convergent manner so that the gap between the conveyor surfaces (B1, B2) also narrows in the transverse direction (TD) in relation to the movement direction, said comminuting space (GS) thus becoming double-converging.

The present invention relates generally to the reclaiming of carpet waste material. More particularly, the invention relates to a method and system for reclaiming carpet components such as yarn, tufting primary, binder, and secondary backing from post-industrial and post-consumer carpet waste in a substantially continuous flow process.

A method for recovering metallic materials from crystalline silicon photovoltaic modules. The method includes removing aluminium frames and junction boxes from the photovoltaic modules to provide photovoltaic sandwich structures. The method further includes shredding the photovoltaic sandwich structures to form photovoltaic sandwich structure particles and electrostatically separating the photovoltaic sandwich structure particles into a first fraction and a second fraction with an electrostatic separator. The method further includes feeding at least a portion of the second fraction to an electrostatic separator for one or more subsequent electrostatic separations into the first and second fractions, wherein the first fraction includes less than 5 percent by weight of total polymer particles and is substantially free of glass particles.
