Waste separator apparatus which comprises: -a frame (11) which delimits a separation chamber (12); -a screening mesh (13) which divides the separation chamber (12) into a shredding chamber (121) and a collection chamber (122); wherein the shredding chamber (121) has a loading mouth (123) and an unloading mouth (124); - a shredder shaft (14) fixed to the frame (11) in a rotatable manner about an operating axis (A) and extending into the shredding chamber (121). The shredder shaft (14) has first cutting hammers (15) and second expelling hammers (16); wherein the screening mesh (13) faces the first hammers (15), in order to receive shredded material, and the discharging mouth (124) faces the second hammers (16). The second hammers (16) have a front edge (17) which is rectilinear and extends substantially parallel to a radial direction (C) with respect to the operating axis (A).

A shredding module of a shredding apparatus is disclosed. The shredding module includes a shredder cassette receiver and a shredder cassette received within the shredder cassette receiver. The shredding cassette includes two shredding shafts arranged in parallel and rotatable about respective rotation axes, and two sets of fingers that cooperate with the two shredding shafts to shred material. The shredder cassette is slidably movable in an axial direction of the respective rotation axes into and out of the shredder cassette receiver.

Embodiments disclosed herein provide an organic matter processing apparatus and method for the use thereof to convert organic matter into a ground and desiccated product. This can be accomplished using a bucket assembly that can grind, paddle, and heat organic matter contained therein. An air treatment system is provided to treat the air interacting with the organic matter.

A machine for shredding inorganic waste is described, comprising: first loading means; a shredding chamber; second shredding means; third unloading means; fourth electronic control means; fifth means for limiting the resisting torque applied to the motor, in such a way as to avoid current absorption that exceeds the capacity of the power supply network, said fifth means comprising one or more mobile elementsand a plurality of blades. A method for operating the machine is also described.

Embassy's under siege have an immediate need to destroy electronic devices. An electronic shredder is provided. A hand crank as backup. This invention relates to a portable electronic shredder. Further, shredder relates to the shredding of electronic devices to a very small size so as to make the shredded remnants untraceable, wherein the mobiles and laptops, CPUs and monitors can be placed for disposing of, following which the electronic devices are exposed to a pulverizer. The pulverizer crushes and cuts the electronic devices to minute remnants. The portable shredder is lightweight, compact and portable, thus making it easy to transport to an e-waste stacked place.

A shredder includes a shredder box having first and second opposite end walls, and first and second opposite side walls that extend between the first and second end walls. The shredder further includes a shredder rotor positioned within an interior of the shredder box, an access door that is pivotally moveable, and a control system for monitoring various parameters to operate the shredder. A side access region is defined between the first and second end walls when the access door is in the open position. The side access region provides access to the shredder rotor and includes an open region defined between the first and second end walls at the second side of the shredder. The open region has an open top which is free of obstructions extending between the first and second end walls.

A dry ice freeze-pulverizer includes pulverizing container and pulverizer main body. The pulverizing container includes a container main body that includes a bottom plate and a side plate erected from a peripheral edge of the bottom plate, has an upper surface opening, and is provided with a pulverizing blade therein, and a lid that closes the upper surface opening and has a vent hole. The pulverizer main body includes a drive device configured to rotate the pulverizing blade. The side plate of the container main body is formed with a vacuum double structure that is obtained by evacuating an internal space formed by opposing metal plates.

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 quick blade repair and replacement enabled apparatus integrating medical waste shredding and sterilization is a dismountable integrally assembled vertical structure. Three chambers, including a loading and stirring, a shredding and a sterilization and discharging chamber are connected into a whole. Two repair gates are respectively on the left and right sides of the shredding chamber, they are designed as a whole together with the rotary blade shaft, when repair and replace the blades, only the repair gates need to be dismounted, and the replacement process can be finished outside the shredding chamber. The stationary blades are pressed on the inner wall of the shredding chamber by using binder plate, and bolts for securing the binder plate are screwed from outside.
