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.

A machine for shredding portions of bituminous material in the solid-state into granules in the solid-state. The machine comprises a pressing member provided with a piston which is axially mobile inside a perforated tubular body along an axis and is provided on the head thereof with an internal concave portion having a shape substantially complementary to a projecting part present in an axial end of the perforated tubular body. On the head of the piston through-openings are made, which extend radially along a direction approximately transversal to the axis and are in communication with the internal space of the concave portion.

The comminution device (100) according to the invention comprises a feed opening (10) for feeding material to be comminuted, a comminution shaft (20) for comminuting the material fed to the device, and a cutting chamber (30), arranged between the feed opening (10) and the comminution shaft (20) and delimited by a cutting chamber wall (40a, 40b). The comminution device according to the invention is characterized in that the cutting chamber wall (40a) can be pivoted. The invention also relates to a corresponding method.

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 adjusting 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 device for shredding material has a shredding rotor, which revolves about an axis of rotation and supports at least one blade, and a first counter-blade which cooperates with the blade of the shredding rotor. A feed plate is provided here, which is mounted to be rotatable about a pivot axis and which is connected to an actuator, in particular to an electric motor, so that, with the aid of the actuator, the feed plate can be brought into a feed position, in which the material to be shredded can lie on a first main surface of the feed plate and can slide along this in the direction of the shredding rotor, and into a first pressing position in which the material to be shredded is likewise pressed with the first main surface of the feed plate against the shredding rotor and shredded between the blade and the first counter-blade.

A shredder device for shredding materials, in particular recyclable material, waste wood and date storage devices, comprises a machine frame, at least one shredder rotor rotatably supported on the machine frame, and at least one feed device for conveying the material to be shredded to the at least one shredder rotor. At least one measuring device for continuously detecting a position of the at least one feed device, a control and/or regulating device for controlling and/or regulating a movement of the at least one feed device, and a signal transmitting device are provided. Measuring signals generated by the at least one measuring device can be supplied to the control and/or regulating device by the signal transmitting device.

A control method of a crusher for elements to be recycled or disposed of, which includes a crushing assembly, to which the elements to be recycled or disposed of are provided, and pushers acting toward the crushing assembly to push the elements to be recycled or disposed of, includes a measuring step of the current absorbed by the crusher, a comparing step of the current value measured against a first predetermined value, and a reducing step of the push intensity of one or more of the pushers toward the crushing assembly in case the measured current exceeds the first predetermined value, the pushers being controlled separately from each other in order to partialize the push force and the push areas.

A control method of a treatment plant for elements to be recycled or disposed of, which includes a crushing roll adapted to reduce the size of the elements to be recycled or disposed of, a screen operatively arranged upstream of the crushing roll and adapted to enable passage therethrough only of elements to be recycled or disposed of having a size larger than a predetermined size, and a conveyor belt arranged operationally upstream of the screen to provide the screen with the elements to be recycled or disposed of, includes a measuring step of the volume of material lying on the conveyor belt; a comparing step of the measured volume value to a first predetermined value; and an increasing step of the vibration intensity of the screen if the measured volume value exceeds the first predetermined value.

A machine is provided including a receptacle for loading waste, a shredder, and a pusher to push waste toward the shredder. The receptacle has a constant cross-section between a waste loading opening and a communication opening with the shredder, and the pusher is a plate translatable in the receptacle, parallel to the axis along which the receptacle has the constant cross-section. The plate is dimensioned such that only an interstice exists between the plate edge wall and the walls defining the receptacle; the plate is movable between a withdrawn position able to be freed from said waste loading opening, and an end-of-travel position situated near the communication opening. The machine comprises a sealing gasket movable between a retracted position, which does not hinder the mobility of the plate in the receptacle, and a sealing position, which produces, in the end-of-travel position of the plate, sealing between the plate and the receptacle walls.
