The invention relates to a shear bar (20), in particular for a forage harvester or another agricultural or silvicultural machine, having a carrier (21) that comprises a cutting region (30); a plurality of cutting elements (31) being set alongside one another in the cutting region (30); the cutting elements (31) comprising a partial edge and at least some of the partial edges forming a cutting edge (32) that is embodied to form, with a knife bar, a cutting engagement for the material to be shredded; the cutting edge (32) forming a transition between a cutting surface (32.1) that is constituted by the cutting elements (31) and extends transversely to the cutting direction, and an exposed surface (32.2) that extends substantially in a cutting direction and indirectly or directly adjoins the cutting edge (32). A shear bar of this kind can be configured to be break-resistant with little complexity in terms of parts and manufacture if provision is made that an infeed element (34), which is embodied as a sintered part made of hard material having an infeed bevel (34.6) profiled on in the sintering process, is provided on or in the row of cutting elements (31); the infeed bevel (34.6) being carried over indirectly or directly into the cutting edge (32); and the infeed bevel (34.6) being arranged at a tilt with respect to the cutting edge (32) in such a way that it is arranged with a setback with respect to the exposed surface (32.2) and toward the cutting surface (32.1).

The present invention provides a glass wool cutting device. The device includes a cutting section housing that has a cutting section chamber, a feed port that is connected to the cutting section chamber, and a discharge port that is connected to the cutting section chamber. A stationary knife is disposed on the cutting section housing to protrude into the cutting section chamber and a movable cutter that has a rotary support body is disposed in the cutting section chamber and a movable knife is supported on the rotary support body to apply a shearing force to the glass wool together with the stationary knife. Additionally, a cutter actuator provides a driving force to the rotary support body.

A detection arrangement for detecting a wear status of a chopping knife arrangement of a chopping device provided for processing a product flow, wherein the chopping device has a revolving chopping drum receiving the chopping knife arrangement and at least one shear bar which cooperates with the chopping knives, with a sensor arrangement which has a magnetic exciter arrangement and a flux conducting device magnetically coupled thereto. The sensor arrangement provides a pole arrangement which forms at least one magnetic pole with a pole surface for conducting magnetic flux, wherein at least a portion of the chopping knife passes the pole arrangement during a rotation of the chopping drum. A voltage induced when a chopping knife arrangement passes the sensor arrangement forms the measured magnetic value, which is used by the evaluation unit to determine the state of wear of the chopping knife arrangement.

Grinding sections for food waste disposers, food waste disposers having grinding sections, and methods of manufacturing food waste disposers having grinding sections are disclosed herein. The grinding sections include an internal wall having a plurality of projections extending into the food receiving area. Grinding inserts are attached to each projection. The grinding sections may be made by molding the grinding section housing with the projections and attaching the grinding inserts into the projections.

A shredder includes a shredder box and a shredder rotor positioned within an interior of the shredder box. The shredder rotor is rotatable about a rotor axis and has a plurality of rotor teeth. An access door is pivotally moveable between an open position and a closed position, the access door defining a side wall of the shredder box when in the closed position. 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.

The comminution device includes a feed opening for feeding material to be comminuted, a comminution shaft for comminuting the material fed to the device, and a cutting chamber, arranged between the feed opening and the comminution shaft and delimited by a cutting chamber wall, which can be pivoted.

A machine for shredding/cutting (200), in particular for biomass and the like, comprising a frame (201) in which a tool holder rotor (100) is rotatably mounted on and which a number of tools (103) are arranged. The tools (103) are arranged in conduits (105) which are formed by side walls (104) and are arranged in a conduit (105) in which at least one inclined deflection element (102) is arranged in front of a tool, and wherein deflection elements (202) are arranged opposite the conduits (105) on the frame (201).

A material reducing machine includes a rotary reducing drum that is rotatable about an axis of rotation and defines a reducing boundary that extends at least partially around the axis of rotation. The material reducing machine includes an infeed conveyor for transporting material to a front portion of the rotary reducing drum and defines a conveyor plane. The material reducing machine includes a mill box at least partially surrounding the rotary reducing drum and including a mill box lid mounted generally above the rotary reducing drum. The mill box lid has an inlet edge positioned above a rear portion of the rotary reducing drum and an outlet edge positioned above the front portion of the rotary reducing drum. The mill box includes an infeed opening that is configured to receive material from a feed table and has an upper opening defined by the outlet edge of the mill box lid.

To improve the comminution of the plant material cut off by a mulching device, a mulching device is provided comprising a rotor which can be rotated in a direction of rotation by means of a shaft and has movable blades, and comprising, with respect to the movable blades, counter-cutting elements that are fixed to the device, that cutting edges of the counter-cutting elements directed opposite to the direction of rotation have a corrugated shape, wherein, in their direction of extension, in particular the counter-cutting elements have at least two convex portions with one concave portion arranged therebetween. The cutting unit can be formed in one piece without any connection.

Embodiments disclosed herein provide a bucket assembly and method of use thereof. The bucket assembly is a relatively lightweight and removable apparatus that can fracture cut, paddle, and heat contents contained therein. The bucket assembly can include a housing that has a curved metal plate and blade array attached thereto. A cut and paddle assembly can rotate within the housing and interface with the blade array to fracture cut contents contained therein. The cut and paddle assembly is also operative to mix the contents to ensure full dispersal within the housing. A flexible heater array is attached to and operative to heat the curved metal plate. The combination of the fracture cutting, paddling, and heating can convert organic matter to a ground and selectively desiccated product.
