A shredder comb is positioned at an interior side of the access door and includes a plurality of shredder comb teeth. When the access door is in the closed position, the shredder comb is positioned at a shredding location to intermesh with the plurality of rotor teeth for shredding material input to the shredder box. The plurality of shredder comb teeth are removable and reversible for use in two orientations.

A heavy-duty shredder, in particular for use in forestry, has a frame; a rotor, which is mounted on the frame so that it can rotate about an axis of rotation and has a drum coaxial with the axis of rotation; a plurality of annular discoidal sectors extending around the drum, integral with the drum and distributed along the axis of rotation so as to form annular cavities between the adjacent annular discoidal sectors; a plurality of first teeth integral with the drum and arranged in the annular cavities between two adjacent annular discoidal sectors; and a plurality of second teeth integral with the drum and aligned with the annular discoidal sectors.

The invention relates to a machine for loosening or cutting the different fibres of the meats for human consumption into small pieces, such as chicken, beef, pork meat or meat from any animal with fibres. This is characterized by having two parallel shafts that rotate in the same direction, wherein by introducing the meat between the two blade-carrying shafts, in relation to the blades of the opposing blade-carrying shaft, permitting the tearing up of the fibres of the meat with the blades, the size of the cut pieces are determined according to the distance between the blades of one blade-carrying shaft and the other with which they intersect. This machine has different transmission means for moving the blade-carrying shafts with the motor force of the motor, given that they engage with the shaft having a speed reducer, which in turn engages with the blade-carrying shafts, wherein these can be pinions that engage with one another or via chains or via pulleys having bands, wherein these cutting machines can be used with combination gear means, as well as pulleys with bands and pinions with chains, which engage with one another or vice versa, wherein the blade-carrying shafts are disposed to be used with peripheral groups in a line of up to 4, 6 and 8 blades on each of the two blade-carrying shafts, and wherein the size of the fibres loosened from the bulk of the fibres is determined by the distance and speed present between the linear peripheral sets between each blade-carrying shaft.

A material reducing apparatus includes a rotary reducing component that has a central rotational axis. The material reducing apparatus includes a reducing element mount attached to the rotary reducing component and a reversible reducing element mounted to the reducing element mount. The reducing element includes a leading front side that has a first cutting edge and an opposite second cutting edge being radially inwardly positioned closer to the central rotational axis from the first cutting edge. The reducing element has a chip curl angle between about 79 degrees and 102 degrees. The reducing element has a radial height extending away from the rotary reducing component. The material reducing apparatus includes at least one chip evacuation arrangement that includes three depth control structures. The depth control structures that are axially adjacent the reducing element have radial heights less than or equal to 25% of the radial height of the reducing element.

A blade for a comminuting machine includes two parallel base surfaces and at least three lateral surfaces. A base surface where two lateral surfaces meet is a cutting device (formed as a cutting edge), and a chip space is adjacent thereto. The chip space is inclined with respect to the base surface such that material comminuted by the cutting device is conveyed toward one of the lateral surfaces. The chip space extends between the two meeting lateral surfaces and has a first material outlet edge at one of the two meeting lateral surfaces and a second material outlet edge at the other of the two meeting lateral surfaces. The first material outlet edge is recessed more than the second material outlet edge so that most of the material comminuted by the cutting device leaves the blade at the first material outlet edge via the inclination of the chip space.

A manufacturing method for a granulated body includes supplying powder agitated by a dry agitator to a wet agitator, and agitating the powder supplied from the dry agitator with a liquid component in the wet agitator by rotating blades so as to form a granulated body. The blades are rotated when the powder is supplied to the wet agitator from the dry agitator. The dry agitator agitates the powder in a dry state, and the wet agitator is positioned perpendicularly below the dry agitator. The wet agitator includes an agitation chamber and the blades rotating around a center axis orthogonal to a direction in which the powder is supplied.

A safety device for a waste processing system having a powered cutting system including a rotor rotatably mounted within a housing is disclosed wherein the improvement relates to a safety device which includes a first safety device disposed within the housing, spaced from the rotor and thereby defining a first gap therebetween through which a cable that has been captured by the rotor assembly is automatically cleaved when disposed between the first safety device and rotor assembly.

A material reducing machine includes a rotor assembly having a plurality of short cutting tools and a plurality of long cutting tools. The short cutting tools are arranged in rows which extend across the length of the rotor assembly, which rows are spaced around the periphery of the rotor assembly. Each of the short cutting tools has a cutting bit with a leading edge that is spaced outwardly from the periphery of the rotor assembly by a short cutter distance. The long cutting tools are also arranged in rows which extend across the length of the rotor assembly, which rows are spaced around the periphery of the rotor assembly. Each of the long cutting tools has a cutting bit with a leading edge that is spaced outwardly from the periphery of the rotor assembly by a long cutter distance that is greater than the short cutter distance of each of the short cutting tools. A breaker assembly includes a plurality of shear blocks, each of which is spaced so as to be aligned with a short cutting tool.

The invention relates to a tool for securing on a tool holder of a machine tool for machining vegetable and/or mineral materials, comprising a tool body which is equipped with a machining attachment that points in a tool feeding direction and comprises a cutting region, in particular a cutting element, and on which a fitting element for meshing with a mating element provided on the tool holder is formed on a support surface facing the tool holder. The dependability and operational reliability when using a machine tool can be ensured if the fitting element has at least two molded regions with different contour regions over the vertical course of the fitting element with respect to the support surface.

A chopping unit (10) of a forage harvester, having a chopping drum (11) bearing chopping blades (15), having a shear bar carrier (17) bearing a shear bar (16) for the chopping blades (15), wherein a top side (20), facing away from the shear bar carrier (17), of the shear bar (16) provides a cutting edge (21) of the shear bar (16), wherein the top side (20) of the shear bar (16) is contoured such that the top side (20) of the shear bar (16) is inclined, at least in a top-side portion (26) facing the chopping drum (11), continuously in the direction of the chopping drum (11) in the contact region with the chopping blades, as seen in the axial direction of the chopping drum (11).
