The container drawer is slidably received by the storage housing.

A method for hardfacing cutting blades used in industrial machinery by creating a channel in the surfaces of an oversize cutting blade that may be filled with hardface weld and machining the outer edge of the main body and channel to create a desired finish profile with a hardfaced edge. Such a cutting blade may additionally have fixed points of reference on the cutting blade which may be used to automate some or all of the process of creating and/or hardfacing a cutting blade to the desired profile.

Featured are a two-stage grinder, an apparatus embodying same and methods related thereto. Such a medical waste grinder includes a first stage and a second stage. The first stage includes spring loaded cutter stacks mounted on two adjacent shafts between two edge plates, each of the cutter stacks including cutters arranged in a helix to create space, each cutter including a number of teeth per blade and including a major diameter and a minor diameter, each cutter turning opposite a fixed counter knife enabling a pinching action against the teeth of the cutter. The second stage includes spring loaded cutter stacks.

Embodiments of the invention provide a cutting blade assembly operably coupleable to a fluid pump. The cutting blade assembly comprises a cutting plate and a cutting hub. The cutting plate may have a front axial surface, an opening, and a plurality of cutting features. Each of the plurality of cutting features may define a pair of cutting edges. The cutting hub may be disposed at least partially within the opening of the cutting plate and may have a cutting arm and fin adjacent to the front axial surface. The cutting arm may define an arcuate front surface having a leading edge. When the cutting plate and the cutting hub are rotated relative to each other, the leading edge of the cutting arm may pass adjacent to the plurality of cutting features so that the relative rotation of the cutting plate and the cutting hub defines a cutting action between the cutting arm and each cutting feature.

A multi-region twin-shaft cutting system for chopping material. The cutting system includes two shafts which are arranged in parallel and are driven in an opposed manner, each shaft is surrounded by a roll body. The system additionally includes a multiplicity of supporting elements, each supporting element is fitted radially around the roll body. The system further includes a multiplicity of severing elements which are of disc- and/or plate-like design and are each fitted symmetrically or asymmetrically tangentially to the circumferential region of the supporting elements.

A rotary cutting machine, having a body base, wherein the body base is provided with a shredding and cutting component capable of rotating about the motor axis by 90; and a power unit for powering the shredding cutter components. The power unit is connected to the shredding and cutting component, and the connector for connecting the power unit is provided on one side of the shredder tube, which having a shredder tube and a feed tube, wherein the feed tube is vertically arranged with the shredder tube. The shredder tube having a shredder tube shell. The strip cutter supporter is arranged in the shredder tube shell, the strip cutter is arranged on the side of the strip cutter support, and the spiral cutter support is clamped on the bottom surface of the strip cutter support, the spiral cutter is arranged on the spiral cutter support, the strip cutter and the spiral cutter are arranged perpendicular to each other. The rotary cutting machine integrates a strip cutter and a spiral cutter in a shredder tube shell, and integrates the two kinds of cuts with different output power modes to facilitate the conversion between the strip cutting and spiral cutting modes.

A crushing apparatus includes a first rotary shaft member, a second rotary shaft member, a plurality of first rotary cutters, a plurality of second rotary cutters, a plurality of first spacers, and a plurality of second spacers, the first rotary cutters and the first spacers being alternately disposed in a first axis direction, the second rotary cutters and the second spacers being alternately disposed in the first axis direction, the first rotary cutters and the second rotary cutters each forming a tearing blade that protrudes in a direction perpendicular to the first axis direction, a portion of each of the first rotary cutters and a portion of each of the second rotary cutters overlapping when viewed from the first axis direction, and a gap being provided between the first rotary cutter and the second rotary cutter in the first axis direction.
