Described is a macerator and process for using the macerator to reduce the particle size of a particulate containing slurry that is introduced to the macerator. The macerator comprises a housing that defines a chamber an inlet and an outlet, the inlet configured to receive a flow of slurry, two or more elongate concentric bodies located within the chamber to define a gap between the surface of the outer body and the inner surface of the housing, the bodies having a first end and a second end, at least one of the bodies rotatable about an axis, and each body comprising a plurality of apertures to define a flow path through each body, from the housing inlet to the housing outlet, a baffle or baffles that extend substantially the width of the gap from the first end to the second end of the bodies to define a first portion that contains the inlet, and a second portion that contains the outlet, and wherein the baffle or baffles substantially inhibit passage of slurry between the two portions via the gap such that the slurry is directed through the body apertures, a motor to drive the rotating body or bodies, one or more injectors that inject liquid into the gap, wherein at least one of the injectors is located in the first portion. The particle size of the outlet slurry is less than the particle size of the inlet slurry.

A bone grinder is provided herein. The bone grinder may have a grinding chamber, an intermediate zone, and a primary cutting element and a secondary cutting element. The intermediate zone may have a first wall and a second wall within the grinding chamber, and the intermediate zone may separate the primary cutting element from the secondary cutting element. The first wall and the second wall may slope inward such that a distance between the first wall and the second wall generally decreases from the primary cutting element to the secondary cutting element. The primary cutting element and the secondary cutting element may be positioned within the grinding chamber to sequentially perform primary cutting operations and secondary cutting operations on a bone. A drive mechanism may operatively engage the primary cutting element and the secondary cutting element.

Embodiments disclosed herein provide an organic matter processing apparatus and method for the use thereof to convert organic matter into a ground and desiccated product. This can be accomplished using a bucket assembly that can grind, paddle, and heat organic matter contained therein. An air treatment system is provided to treat the air interacting with the organic matter. The processing apparatus is outfitted with sensors and switches that provide feedback data to a processing unit and a safety monitor. The feedback data is used to monitor the operating conditions and the status of various components, as well as control the operation of the processing apparatus. In addition, the feedback data is used to enforce a safety protocol.

An implant shredder includes a base and a cutting member. The base includes a first chamber and a second chamber intercommunicating with the first chamber. The first chamber includes an inlet. The second chamber includes an outlet. The cutting member is received in the second chamber. The cutting member is driven by a driving member to rotate. The cutting member includes a plurality of cutting edges located on a circumference of a same radius. The plurality of cutting edges is rotatably disposed adjacent to a location intercommunicating with the first chamber. An implant forming method includes creating data of an outline of an implant; producing a shaping mold based on the data; and cutting a to-be-processed object with the implant shredder, mixing the cut to-be-proceed object with a biological tissue glue to obtain a raw material, and filling the raw material into the shaping mold to form the implant.

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).

An apparatus and method of mechanical milling and grinding of various materials at temperatures ranging from sub-ambient conditions to well-below their ductile-brittle transition temperature (DBTT) are presented. In one embodiment the present invention entails the design of a cryogenic milling chamber compatible with horizontal high-energy mills. The new design and configuration of the milling vessel provides robust and efficient cryomilling of various materials with no contact between the cryogen and the powders. Some embodiments of the invention improve the heat removal rate from the non-uniform heat load generated by the impact energy deposited into the chamber wall by the milling media.
