A grinder accessory is useful for a pump in a wastewater application. The grinder accessory has a cutter plate and a cutting body that co-act on solids, especially fibriform solids. The cutter plate has first and second planar faces, mounted in an inlet of the pump, with a plurality of through holes and a central aperture. The cutting body is poised atop the first planar face and extends through the central aperture to rotationally couple with a drive shaft of the pump. A central hub of the cutting body has a plurality of arms that extend radially proximate to the first planar face, so that a leading edge of the arms interacts with the through holes on solids passing therethrough. A housing defines a cutting chamber around the cutter plate and the cutting body to protect them and to induce swirling action.

A shredder includes a shredder box having first and second opposite end walls, and first and second opposite side walls that extend between the first and second end walls. The shredder further includes a shredder rotor positioned within an interior of the shredder box, an access door that is pivotally moveable, and a control system for monitoring various parameters to operate the shredder. A side access region is defined between the first and second end walls when the access door is in the open position. The side access region provides access to the shredder rotor and includes an open region defined between the first and second end walls at the second side of the shredder. The open region has an open top which is free of obstructions extending between the first and second end walls.

An animal slurry macerator (1) comprising a housing (2), a slurry chamber (3) in the housing (2) for receiving slurry from a slurry inlet (6) on the housing (2), a rotatable cutting plunger (4) in the slurry chamber (3) for macerating slurry, and a plurality of slurry outlets (7) on the housing (2) for discharging macerated slurry from the slurry chamber (3) wherein the slurry outlets (7) are provided with air-valves (8) at the housing (2) to facilitate air flow through the slurry outlet (7).

A comminution apparatus, a method for replacing wear parts of such an apparatus and a cutting table unit for use in such an apparatus. The apparatus includes a cutting module, a drive module and a top module. The main wear parts are present in the cutting module, which may be replaced, in its entirety or in part, without disconnecting the drive module from the apparatus or from an external power source.

A food recycler can include a case having a case volume between 8.79 liters and 35 liters, a control system, a user interface in electrical communication with the control system, and a bucket being configured with a bucket volume, wherein a ratio of the bucket volume to the case volume is between 0.0717 and 0.2857. The recycler can include a motor in communication with the control system, the motor being configured adjacent at least in part to the bucket, a gearbox configured below the bucket and in mechanical communication with the motor, a filter system having at least one filter and configured to receive air from a top portion of the bucket and a drying component configured to remove water from waste food items.

A modular industrial reducing machine is provided. The reducing machine includes a removable cutting tray releasably coupled to a first and second axial endwalls in a base frame. Additionally, the removable cutting tray includes a plurality of non-rotating anvils designed to interact with a plurality of cutters during reducing operation to reduce material in the reducing compartment.

A food recycler includes a case, a control system within the case, and a set of user interface components that are usable to at least cause the control system to initiate a food recycling cycle. The food recycler also includes a motor within the case and a bucket that has a volumetric capacity between 2.51 and 10 liters. A filter system configured to accommodate air filters is also included in the case of the food recycler. To remove water from waste food items, the food recycler includes a drying component.

The present disclosure relates to a cutter bar for chopping machines. The cutter bar includes a cutter bar body that defines an edge groove. The edge groove includes a groove bottom and a groove sidewall. The groove sidewall is formed by the material of the cutter bar body. A wear protection structure extends along a surface of the cutter bar body from the edge groove. The wear protection structure is built up on the surface of the cutter bar body as an additively manufactured metal powder application layer. At least one carbide strip is secured to the edge groove and forms the cutting edge. The carbide strip can be fastened to the edge groove by means of a bonding agent, such as solder or adhesive.

Grinding mechanisms for food waste disposers, and food waste disposers having grinding mechanisms are disclosed herein. The grinding mechanisms include a stationary grinding ring that includes a plurality of grater teeth, and a rotating shredder plate that includes at least one lug. The at least one lug may have at least a portion that is movable with respect to the top surface of the rotating shredder plate, or may be fin shaped.

A strand pelletizer for pelletizing a strand of material comprises at least one cutting edge and an opposite cutting edge. The opposite cutting edge is arranged on a base body which is displaceable relative to a support body. The base body is independently displaceable in a linear manner relative to the support body and pivotable about at least one pivot axis. The strand pelletizer enables simple and precise adjustment of the opposite cutting edge and an associated cutting gap.
