The invention relates to a device and a method for the dissociation of tissue. In one embodiment, the device has at least one dissociation unit, for receiving a tissue sample, which is disposed at least partially in a pot-shaped cell strainer. In addition, the invention relates, in one embodiment, to a device and a method for the dissociation of tissue, the tissue being dissociated by a grinder having mutually movable rows of teeth which cut the tissue when moving past each other in the one direction and grind the tissue when moving past each other in the opposite direction.

A method of producing a powder suitable for additive manufacturing and/or powder metallurgy applications from a precursor particulate material comprising: subjecting the precursor particulate material to at least one high shear milling process, thereby producing a powder product having a reduced average particle size and a selected particle morphology.

In one aspect, a cutter system for a waste disposal may generally include a cutter ring having an upper surface and a lower surface. In addition, the cutter ring may define a plurality of cutter slots. Each cutter slot may extend between a top end and a bottom end and may be defined by a first curved sidewall and a second curved sidewall. The first and second curved sidewalls may extend between the top and bottom ends such that each cutter slot defines a curved profile extending axially and circumferentially between the upper and lower surfaces of the cutter ring.

A cutting blade assembly establishes a bidirectional and/or multifaceted scissor-type cutting action to efficiently and effectively process various types of debris encountered by the cutting blade assembly. The assembly includes a cutting plate and a cutting hub configured for relative rotation. A cutting slot is formed in the cutting plate and intersects the axial face to define a cutting edge at the intersection of the cutting slot and the axial face. The cutting hub has a cutting arm positioned adjacent to the axial face. When the cutting plate and the cutting hub undergo relative rotation, the cutting arm passes adjacent to the cutting edge to perform a scissor-type cutting action.

Machines and methods adapted to process, for example, to reduce the size of, disperse, or homogenize, a variety of materials and compositions. Such methods and machines are capable of reducing the size of a material and dispersing the material in a liquid by cutting the material with knives located along a perimeter of an annular-shaped cutting head, causing the cut material to flow radially outward from the cutting head through gaps between the knives, and flowing a liquid through passages in the cutting head that cause the liquid to cascade around the knives of the cutting head in an axial direction of the cutting head.

A cutting blade assembly including a cutting plate, a plurality of cutting slots formed in the cutting plate, and a cutting hub. The cutting plate includes an axial face and a central opening. The plurality of cutting slots are circumferentially spaced about the central opening. Each of the plurality of cutting slots intersects the axial face and defines a respective axial cutting edge at an intersection of each of plurality of cutting slots and the axial face. Each of the plurality of cutting slots defines a base surface that is nonparallel to the axial face. The cutting hub is positioned in the central opening and has a cutting arm adjacent to the axial face.

The micronizing apparatus includes: a body having a transfer space where hydrogel is transferred, and a discharge space where ground hydrogel is discharged; a rotation shaft disposed in the transfer space, wherein at least one screw is formed on an outer perimeter surface of the first rotation shaft, to transfer the hydrogel along a longitudinal direction of the body; a rotor installed on the rotation shaft so as to rotate together with the rotation shaft, wherein a plurality of rotor blades and a plurality of rotor recesses are alternately formed along a circumferential direction on an outer perimeter part of the rotor; and a stator surrounding the rotor with an air gap between the rotor and the stator, which is a predetermined distance between an outside diameter of the rotor and an inside diameter of the stator, and is fixed to the body.
