A comminuting machine for comminuting material includes a machine frame, a comminuting rotor rotatably mounted on the machine frame, and a material feed area. The material feed area has a wall section over which the material to be comminuted can be supplied to the comminuting rotor and which is designed to be stationary during a comminuting operation of the comminuting machine and can be pivoted about a rotational axis during a maintenance operation of the comminuting machine. Because the rotational axis is designed to be releasably lockable, a second releasably lockable rotational axis is provided together with the first rotational axis, and the wall section of the material feed area can selectively be pivoted about the first or second rotational axis during the maintenance operation of the comminuting machine.

Filter material, mainly in form of industrial remnants from the production of the filter fillings, is processed without the intake of the heat in such a way that it is cut in the disintegrator (4) at the presence of the air, where the material is during retention time repeatedly led to the contact with the rotating blades and bunches emerge in the disintegrator (4) through aeration. The flat carrier (3) is thus at least partially disintegrated to the original fibers (1); the released fibers (1) intertwine into bunches and the active carbon (2) is released from the original bond with the flat carrier (3). The swirl (vortex) created inside the disintegrator (4) carries the dust particles of the active carbon (2) and they adhere to the surface of the fibers (1). Part of the released active carbon (2) isafter the separationcarried away from the emergin bunches, which in the lower part of the disintegrator (4) run through the sieve out of the disintegrator (4). The resulting product is advantageously applicable as heat and noise isolation in all fields of technology, for example construction. The separated active carbon (2) in form of granules is also a resulting product of processing.

The invention relates to a device (10; 50) for mechanically comminuting materials, including a vertically extending comminuting chamber (14) having an upwardly extending supply side (15) and a downwardly extending discharge side. The comminuting chamber is enclosed by an in circular cylindrical and/or conical downwardly expanded comminuting chamber wall (12), and in which at least one rotor (16, 18) rotating about a vertical rotor axis (R) is arranged, which is provided with striking tools (38) that extend radially into the comminuting chamber, at least during operation. The rotors(16, 18) are held in a stationary manner with respect to a support base (20) of the device, and the comminuting chamber wall is supported on the support base. According to the invention, the comminuting chamber wall is held in place by way of a lifting device in the direction of the rotor axis (R) in a height adjustable manner relative to the support base (20). The lifting device (36) has a working position, in which the lower edge of the comminuting chamber wall (12) is arranged close to the support base (20) or to a part connected thereto, and a maintenance position, in which the lower edge (32) of the comminuting chamber wall (12) is vertically raised above at least one of the striking tools (22, 24). The invention allows easy maintenance and an uncomplicated exchange of the striking tools of the comminuting device.

A comminution device can include a crushing body extraction mechanism. The crushing body extraction mechanism can be configured to permit one or more crushing bodies (e.g. rollers of a roller press, etc.) to be continuously moved linearly away from a frame to expose the crushing bodies from the frame. In some embodiments, the extraction mechanism may be configured to utilize one or more rack and pinion mechanisms. The pinion for each such mechanism may be powered by one or more rotary motors or other type of rotary drive mechanism. In other embodiments, the extraction mechanism can include one or more rack and ratchet mechanisms. Each rack and ratchet mechanism may include a hydraulic cylinder or other linear actuator that is extendable and retractable for actuating motion of a ratchet along a rack having columns of differently angled steps to facilitate extension and retraction of one or more crushing bodies.

A method and related apparatus for liberating particles with specific dimensions from a moist Municipal Solid Waste Incinerator ash (MSWI ash) material comprising particles with differing dimensions. In an aspect, the method comprises feeding an amount of the material in a particle stream, striking the particle stream with a striking body to impart a sudden change in direction of the particle stream, receiving at least a part of the stricken particle stream on a moving surface, and transporting the received particle stream to an outlet beyond the receiving area where the particle stream is divided in a first fraction rich of particles of a first group of particle dimensions, and at least a second fraction rich of particles of a second group of particle dimensions, which second fraction is substantially depleted of particles of the first group of particle dimensions.
