A shredding machine for domestic or office use having a feed passage 3 leading to a cutting mechanism 10, 11 powered by an electric motor, has a thickness measuring device 15 for measuring the thickness of bundles of paper fed through the feed passage and the machine is controlled by a microprocessor which receives signals from the thickness measuring device and prevents the cutting mechanism from being energised if the thickness measured is above a threshold determined by the microprocessor. The thickness gauging device is deactivated during shredding until the material is shredded so that rippling or flapping of the material within the feed passage will not cause false readings as to the amount of material inserted into the feed passage.

A preload type granulator includes a drive unit, a transmission unit including a transmission sleeve rotatable by the drive unit and having oblong slots cut through the peripheral wall thereof, two elastic modules with different spring coefficients connected in series and axially mounted in the transmission sleeve, and a cutting unit including a connecting shaft abutted with a bottom side thereof against the elastic modules and fastened to the transmission sleeve by screw bolts that are respectively inserted through the oblong slots and threaded into the connecting shaft, a cutter holder mounted on the connecting shaft and a plurality of cutting tools mounted on cutter holder. Thus, the series of elastic modules generates a constant spring pressure to adjust the pressure between the cutting tools and the die face, controlling the friction between the cutting tools and the die face.

Granulator mill (1) comprising granule chamber (3) comprising at least one non-rotatable blade (4), rotatable rotor (8) arranged inside the granule chamber (3), the rotor (8) comprising a number of blades (10) which are arranged for cooperation with the non-rotatable blade (4), a infeed hopper (5) for feeding waste into the granule chamber, a grid arranged in the granule chamber, where through granulated waste is allowed to pass to an outfeed hopper (30). A scraping device (15) is provided in a space (14) located axially in between a housing (2) and the rotatable rotor (8) and the scraping device (15) is attached to the housing (2).

The invention relates to a crushing apparatus (1) for crushing material to be crushed, especially for use in the field of recycling and waste processing, with at least one crushing roller (2) that can rotate about an axis of rotation (3), at least one drive device (4) for driving the crushing roller (2), and a frame (5) for supporting and mounting the crushing roller (2) and the drive device (4). According to the invention, it is provided that the crushing roller (2) and the drive device (4) form a common assembly connected to at least one damping device (16), which is frictionally and/or elastically mounted in or on the frame (5).

A paper shredder with counter-rotating shredder blades coupled to a shredder motor, including a paper tray having a floor and being shaped to receive paper. The floor has an offset slot therein adjacent to the counter-rotating shredder blades. The engagement wheels partly protrude through floor, adjacent to the offset slot. The engagement wheels frictionally engage paper and turn towards the offset slot to force paper into the shredder blades. Also, a dentate catch disposed in each corner of the paper tray temporarily holds an affixment while a sheet of paper held by the affixment is being frictionally engaged by the engagement wheels to enter the slot for comminution. A PAPER FULL sensor, a DOOR OPEN sensor, an OVERLOAD sensor, an OVERHEAT sensor, a paper-in-tray sensor, a paper-at-entry sensor, a SAFETY LOCK sensor, and a cover door open/closed sensor are provided, as are AUTO and MANUAL modes of operation.

A material reduction machine includes a prime mover driving a cutting mechanism. An infeed portion engages a piece of material to feed it forward to the cutting mechanism. A sensor senses a machine load parameter via the cutting mechanism and/or prime mover and reports a signal to a controller operatively coupled to the infeed portion to control sequential cutting cycles on the piece of material. The controller utilizes a stored first stop threshold value for stopping a first cutting cycle and continues monitoring the signal as machine load increases momentarily after reaching the first stop threshold. The controller determines and adopts a second stop threshold value based on observation of the machine load parameter indicative of maximum load during the continued monitoring following attainment of the first stop threshold, and further being based on a stored correction factor. The second stop threshold value is used for a second cutting cycle.

A system for shredding medical waste, the system comprising a medical waste treating chamber being an interior of an enclosure disposed within an environment which is not to be polluted, a motor, a shredder seated in the chamber and including a motor-driven shaft and blades rotated by the shaft, the shaft extending through the enclosure thereby to define an interface between the waste treating chamber and the environment, and interface seal apparatus preventing leakage of at least fluids from the medical waste treating chamber into the environment, via the interface.

The present invention relates to the field of garbage landfill. The present invention discloses a classified landfill device and method for garbage landfills, and the problem solved by the present invention is that the device proposed in the above background absorbs metals in the garbage using a magnet, but when the surface of the magnet has absorbed a large amount of metal, the device needs to be closed to treat the metal adsorbed on the surface of the magnet. The present invention comprises a screening mechanism, crushing mechanism and discharge mechanism. According to the classified landfill device and method for garbage landfill, the second crushing knife is set at an angle to divert the falling garbage to the front and rear sides, so that the two first crushing knives and the second crushing knife cooperate to crush the garbage respectively to avoid excessive accumulation of garbage.
