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).

An emulsion system is provided. The system includes a shaft that supports a plurality of cutting assemblies and screens in alternating order, wherein the cutting assembly rotates with respect to an in close proximity to the screen. The cutting assemblies include a plurality of cutting elements that extend radially outward from a hub and are positioned at consistent radial spacing along the perimeter of the hub. Each cutting element includes front and back edges that cut food particles in conjunction with holes within the screen, wherein the front and back edges are substantially perpendicular.

A defibrating device and sheet manufacturing apparatus attract and remove metal fragments when metal fragments are mixed with fibrous material. A defibrating device has a main unit with a defibration section configured to defibrate fibrous material, and a swirl section configured to produce a rotational current, and by the rotational current cause the fibrous material to rotate and flow into the defibration section. The main unit has a magnet unit that is disposed to the swirl section, and has a magnet that attracts by magnetic force metal fragments conveyed with the fibrous material to the swirl section.

An apparatus includes a material feeder having an input and an output, a reducing nozzle attached to the output of the material feeder, an electrically conductive tube having a first end surrounding at least a portion of the reducing nozzle, and an induction coil surrounding all or part of the electrically conductive tube. A method for treating organic matter includes inductively heating the electrically conductive tube using the induction coil, and supplying the organic matter to the input of the material feeder. The organic matter is pushed through the reducing nozzle using the material feeder, such that the organic matter forms a continuous tube, semi-continuous tube or pellets of organic matter that is pushed through the electrically conductive tube. The continuous tube, semi-continuous tube or elongated pellets of organic matter is treated using the heat within the electrically conductive tube.

A shredder (1) is provided for comminuting organic material to form shreds. The shredder has a shredding chamber (2) provided with rotatable cutting devices (3), wherein the shredder (1) furthermore includes a fan chamber (6) containing a fan (7) which is connected to the shredding chamber (2) via a passage (4), wherein the fan (7) is configured to generate a suction force which will suck the shreds out of the shredding chamber via the passage and will remove these from the fan chamber (6) via a discharge opening (8). In contrast to the known shredders, this shredder (1) no longer has a discharge opening in the shredding chamber and, in addition, no longer requires a calibration grille.
