A device to reduce solid state drives (SSD) and the like digital media storage devices into particles less than 2 mm maximum edge length. The device is particularly adapted to disintegrating 1.8 and 2.5 solid state drives at a rate of about 360 HDD/hr or 720 SSD/hr with a throughput of about 10 seconds. A blade assembly is designed to provide multiple cutting angles while rotating at 520 rpm to maintain a low decibel rating.

Method and apparatus (100) 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 (103) through which a piston circulates (104) inside an extrusion cavity (106), which comprises three sections (107, 110, 111) and is fed with a parget obtained after pre-processing the waste. The end (115) of the third section (111) is connected to the reactor (112) through an opening (114). The reactor's longitudinal shaft is formed by a rotatory steel shaft (116) in which some steel blades are arranged (108), 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 (300) to discharge the parget present in the boundary area through some openings (304), once it has been processed by a series of pressure, vibration energy and decompression cycles.

Shredding device for shredding material comprising a housing: a rotor and one or more counter blades which are arranged in the housing such that they interact for shredding the material; a pusher element that is movable such that it pushes the material to be shredded in the direction towards the rotor and the counter blades; a hopper for feeding the material which is arranged movable on the housing between a first and a second position, where, in its first position, the material may be fed to the rotor and the counter blades, and in its second position, the rotor and the counter blades are freely accessible from the exterior of the shredding device.

A method for the reduction and/or removal of pathogenic agents and microorganisms contained in solids, comprising the steps of purification of the starting material to dispose of materials that combine a great size and extreme hardness and malleability; and the adjustment of the humidity degree of the material obtained in step of purification, and the grinding and heating of the material obtained in the step of adjuisting the humidity, where the grinding and heating are carried out simultaneously by subjecting the material to a high pressure while at the same time its temperature is increased by means of an increase in the pressure on the material and the friction caused between the material and the grinding means. And A machine to carry out the method, comprising a front chamber for the entrance of the material; a contiguous rear chamber associated with the entrance chamber, by means of which the processed material is expelled; said contiguous rear chamber containing a grinding means that rotates when it is actuated by an engine; and a piston that enters into the front chamber running along said chamber into the rear chamber until it reaches a grinding means, where the grinding means consists of a solid, hard and heavy cylinder associated with a transverse axis, said cylinder being provided with a set of longitudinal slots from base to base that form edges with the cylinder surface.

A high crushing efficiency medical waste treatment machine includes a crushing cylinder, a crushing knife set provided at the bottom of the crushing cylinder, an intermittent material discharge mechanism set on one side of the crushing knife set, a pressurizing mechanism slidingly set along the axis of the crushing cylinder on the other side of the crushing knife set. The pressurizing mechanism includes a mounting frame slidingly connected to the inner wall of the crushing cylinder, the mounting frame rotatably connected to a material tumbling plate made of magnetic material; when the intermittent material discharging mechanism discharges material, the pressurizing mechanism moving in a direction close to the crushing knife set; when the intermittent material discharges mechanism stops discharging material, the material tumbling plate rotates.

A device for shredding objects includes a feed tray for the reception of objects to be shredded, a roller shredder with at least one powered roller and a further working means in the form of a roller or a comb-shaped counterpart, between which a working gap is formed, in order to shred objects from the feed tray and convey them through the working gap, and a pushing element which can be moved in the feed tray and by means of which the objects to be shredded can be conveyed to the roller shredder. The feed tray can be closed on an upside by a removable cover and an interior space of the feed tray is connected to a suction device for producing a negative pressure.

Interchangeable cartridge devices, driven by an external actuator, for use in grating an ingestible substance. The devices may include an assembly with an cavity defining structure and a grating blade coupled to the assembly. A plunger moves within this cavity and is biased towards the grating blade. The plunger is configured to push a substance to be grated into and through the grating blade. Various embodiments are disclosed featuring narrow and wider cavities, different driving structures, a plunger with a plurality of independently biased sections, and releasable components for repair, cleaning and replacement, among other features.

A machine to carry out the method for the reduction or removal of pathogenic agents and microorganisms contained in solids, comprising a front chamber for the entrance of the material; a contiguous rear chamber associated with the entrance chamber, by means of which the processed material is expelled; said contiguous rear chamber containing a grinding means that rotates when it is actuated by an engine; and a piston that enters into the front chamber running along said chamber into the rear chamber until it reaches a grinding means, where the grinding means consists of a solid, hard and heavy cylinder associated with a transverse axis, said cylinder being provided with a set of longitudinal slots from base to base that form edges with the cylinder surface and where the space between the cylinder surface and the rear chamber inner wall is smaller than 5 mm.
