An implant shredder includes a base and a cutting member. The base includes a first chamber and a second chamber intercommunicating with the first chamber. The first chamber includes an inlet. The second chamber includes an outlet. The cutting member is received in the second chamber. The cutting member is driven by a driving member to rotate. The cutting member includes a plurality of cutting edges located on a circumference of a same radius. The plurality of cutting edges is rotatably disposed adjacent to a location intercommunicating with the first chamber. An implant forming method includes creating data of an outline of an implant; producing a shaping mold based on the data; and cutting a to-be-processed object with the implant shredder, then mixing the to-be-proceed object with a biological tissue glue to obtain a raw material, and filling the raw material into the shaping mold to form the implant.

The system and method of processing a used wind turbine blade provides for processing of a blade at the site of the windmill rather than transporting the blade to a processing facility. The blade may be held stationary while a cutter, such as a drum or plate with cutting teeth, is moved along a portion of the blade to shred the blade. This shredding may occur within a cutting chamber. The blade may be fed into the cutting chamber with a feeder. Smaller particles may be removed or filtered from the air within the cutting chamber and larger particles may be removed and collected in a receptacle. Portions of or the entire system may be made mobile by mounting or otherwise connecting the system to a mobile support, such as a trailer.

The comminution device includes a feed opening for feeding material to be comminuted, a comminution shaft for comminuting the material fed to the device, and a cutting chamber, arranged between the feed opening and the comminution shaft and delimited by a cutting chamber wall, which can be pivoted.

Automatic paper shredder having a paper pressing mechanism, which includes upper shredder cover, lower shredder cover, paper support box, paper pressing plate, cover plate, spindle and two spindle holders. Upper cover is connected to lower cover. Paper support box is above the lower cover forming a cavity for to-be-shredded paper. Fixed ends of paper pressing plate and cover plate are around the spindle, so free ends of paper pressing plate and cover plate can rotate coaxially. Two ends of spindle are respectively disposed in two spindle holders, so spindle can rotate. Two spindle holders are connected to upper cover to connect cover plate and paper pressing plate to upper cover. Paper pressing plate is disposed below cover plate and for pressing to-be-shredded paper placed on paper support box when a user closes cover plate.

Method and apparatus for transforming organic and inorganic solid urban waste into aggregates, comprising an extruding machine connected to a reactor. The extruding machine is formed by an extrusion cylinder through which a piston circulates inside an extrusion cavity, which comprises three sections and is fed with a parget obtained after pre-processing the waste. The end of the third section is connected to the reactor through an opening. The reactors longitudinal shaft is formed by a rotatory steel shaft in which some steel blades are arranged, whose ends play the roles of cutting, hammering, punching and hydraulic helix as they rotate. Between the end of the blades and the wall of the reactor, there is a clearance of more than 0.1 mm of thickness. The reactor has a discharge valve to discharge the parget present in the boundary area through some openings, once it has been processed by a series of pressure, vibration energy and decompression cycles.

A shredding device for shredding materials is provided, the shredding device having: a housing, a rotor in the housing, a pusher element which is pivotable about an axis, so that it pushes the material to be shredded towards the rotor, and a service hatch which is mounted on the housing and configured in such a manner that in an open state it exposes a first opening in the housing with access to a rotor and a second opening in the housing with access to the underside of the pusher element when the latter is pivoted upwardly.

A self-destructive storage system and method is disclosed. The system includes a digital storage, and a destruction mechanism located proximate the digital storage and configured to physically render the digital storage unreadable upon activation. The system also includes a controller having a processor and a memory. The controller is communicatively coupled to the destruction mechanism and is configured to activate the destruction mechanism in response to at least one of the receipt of a destroy command and the satisfaction of a predefined condition. The system also includes a wireless network interface that is communicatively coupled to the controller and a wireless network. The digital storage device, the controller, and the destruction mechanism are coupled to a drive enclosure.

A stomper for a food grinder comprises a distal end adapted to push food into a receiving tube of a food grinder, a proximal handle end adapted for a user to grasp the stomper while pushing food into the receiving tube of the food grinder, an elongated shaft between the distal end and the proximal handle end, a channel defined in the proximal handle end, and a bayonet projecting from one or more internal walls of the channel. The bayonet is adapted to engage a protrusion on an auger of the food grinder to apply a pulling force to remove the auger from the food grinder.
