According to the invention, the sieve element (41) is spring-mounted on the base comb (II).

A machine or system and related method for breaking and reducing the bulk size of one or more objects and comprising: a frame, a reception chamber and a size reduction mechanism. The size reduction mechanism includes a drum rotatably coupled to the frame and configured to oscillate relative to the frame between a first position and a second position about a longitudinal rotational axis; a cutting member coupled to the drum and extending therefrom, the cutting member being configured to penetrate through one or more of the objects in the reception chamber during operation as the drum rotates from the first position to the second position during each oscillation cycle; and a breaking screen comprising a series of spaced breaking members configured to cause further breakdown of the one or more pieces of the one or more objects during operation as the drum rotates toward the second position during each oscillation cycle and forces the one or more pieces against the breaking members. An optional chute may be coupled to the outlet of the machine or system for further compacting and disposing of the bulk material output by the machine.

The invention relates to a crushing device with a comb system (I), wherein the crushing device consists of at least one crushing roller (1) rotatably mounted in a machine frame with at least one crushing tool (2) arranged thereon, wherein the crushing device comprises at least one counter blade (3) which cooperates with the crushing tool (2), wherein the comb system (I) comprises at least one base comb (II) on which the at least one counter blade (3) is arranged and on which at least one screening element (41) can be arranged as a component of a screening device (4), wherein the screening device (4) during intended use at least partly encloses the crushing roller (1) and the screening element (41) is spring-mounted with a suspension (6) on the base comb (II).

The invention is characterized in that the suspension (6) comprises an end position limit (B).

Granulator mill (1) comprising granule chamber (3) comprising at least one non-rotatable blade (4), rotatable rotor (8) arranged inside the granule chamber (3), the rotor (8) comprising a number of blades (10) which are arranged for cooperation with the non-rotatable blade (4), a infeed hopper (5) for feeding waste into the granule chamber, a grid arranged in the granule chamber, where through granulated waste is allowed to pass to an outfeed hopper (30). A scraping device (15) is provided in a space (14) located axially in between a housing (2) and the rotatable rotor (8) and the scraping device (15) is attached to the housing (2).

The present invention relates to a counter-blade, in particular, for a wood chipper, for producing wood chips, comprising at least one cutting edge made of a hard material, and a support surface leading to the cutting edge. According to the present invention, the cutting edge is made up of a plurality of hard material elements that are arranged next to one another along the cutting edge on a main member. This results in a counter-blade having a long service life.

A cutter assembly and high volume submersible shredder pump. These are for reducing the size of solids within a liquid which is to be pumped by chopping, grinding, shredding or cutting. An improvement over prior designs employs a cutting assembly having a rotary cutter and a cup-shaped, concave, plate cutter having a circular horizontal cross-section. The plate cutter is adapted for mounting to an intake opening of a stationary volute, associated with a shredder pump. The cutting assembly has cutting lobes having a grooved surface which mate with corresponding grooves of the shaped, concave, plate cutter. As a result, many more cutting surfaces are provided which more effectively and quickly shred the solid materials within the liquid to be expelled.

A portable grinding/shredding/chipping system with a drive track assembly which is manipulatable to facilitate altering the orientation of the portable grinding/shredding/chipping system. This arrangement results in improved loading and processing, of both long and short materials, as well as facilitates connection of a transport dolly and a transport truck/tractor without requiring any additional lifting mechanism. A pivotable housing provides greater access to the rotor and has an over-center arrangement which prevents the pivotable housing from inadvertently moving or pivoting back into engagement with the rotor. The portable grinding/shredding/chipping system is provided with a belt drive assembly which facilitates modification of the rotational speed of the rotor by merely replacing a sheave of the belt drive assembly. Lastly, both head and tail pulleys are driven by a respective motor so that a catinary of the discharge conveyor is radiussed which shortens an axial length of the system.
