A mill includes a housing with a first end portion, a second end portion, and a lateral area disposed therebetween. The housing includes a raw material inlet, an air inlet, a recirculated material inlet, and a material outlet. An impeller is supported by the housing and includes a shaft disposed along the longitudinal axis of the housing, with a plurality of curved blades. A method for milling includes receiving a material of a first size range, introducing the material to an apparatus via a first inlet and introducing air into the apparatus via a second inlet. The method also includes agitating the material via an impeller, where the agitation reduces at least some of the material to a second size range by the time the material reaches an outlet of the apparatus. The processed material is delivered to subsequent processing operations.

The various embodiments disclosed and pictured illustrate a multi-connector hammer for comminuting various materials. The illustrative embodiments pictured and described herein are primarily for use with a rotatable hammermill assembly. The multi-connector hammer includes a connection portion having a rod hole therein, a contact portion for delivery of energy to the material to be comminuted, and a multi-connector neck portion affixing the connection portion to the contact portion. In other embodiments, a shoulder is positioned around the periphery of the rod hole for added strength. In still other embodiments, a neck reinforcement is positioned along a portion of the neck for increased strength. A weld or plurality of welds may be affixed to various surfaces of the contact portion to aide in comminuting and/or longevity of the multi-connector hammer.

An apparatus for rotationally grinding, pulverizing, or comminuting bulk materials. The apparatus comprises a material processing component fed at an input end by a hopper. The material enters the material processing component for processing and is propelled out of an output end through an outlet into a tray or piping. The material processing component comprises a cylinder with an exterior insulating compartment and a replaceable inner liner. The cylinder defines a horizontal stationary work area. A rotatable shaft penetrates the cylinder along an axis of the working area. A plurality of working bodies are attached to the shaft in a narrowing helical orientation that also narrows in distance between working bodies from front to back. The working bodies are configured to comminute the material and direct it toward the outlet as the material passes through the working area.

A waste grinding apparatus (101) including a rotor having a central body (13) defining at least one radial vane (15a, 15b), provided, at its end (17a,17b) distal relative to a rotation axis (“S”) of the rotor (11), with a hammerhead (19) in which a first, knocker impact surface (21) adapted to operate when the rotor (11) rotates in a first, clockwise or counter-clockwise direction, and a second, wedge-shaped impact surface (23) adapted to operate when the rotor (11) rotates in a second direction opposite to the first direction, are defined.

The invention relates to the method and device for milling and separation into fractions of solids and granular materials in a controlled airflow. The device for milling and separation of solids and granular materials consists of a round milling chamber with a system of pneumatic separation comprising of a vertical cylindrical body that has an uploading slot for solids and granular materials and unloading channels for the milled products of light, medium and coarse fractions. A rotating disc and a conical divider are located inside the vertical cylindrical body. The rotating disc has removable hammers and removable blades of different sizes and configurations. The system of pneumatic separation consists of a milling chamber, an air slugcatcher, channels for the milled material, and a chamber of higher pressure. Such a construction of the device allows to obtain products of the highest quality, and to improve the separation by dividing the material into three fractions: light, medium and coarse.

A multifunctional extruding-shearing machine and an application of the machine is disclosed. The main technical feature of the machine is that the outer surface of the wear-resistant component made of hard alloy on the rotor pin and stator pin is covered with 4-12 step teeth, and the surface of the step teeth of the stator pin faces the inside and the surface of the step teeth of the stator pin faces outside when the equipment is assembled, and the rotor pin wear-resistant member tip faces the stator pin wear-resistant member tip. The above structural features ensure that the rotor pin and the stator pin can clamp the material particles and exert extrusion shear force on them to force them to be crushed.

The present disclosure relates to a system for a material reducing machine that allows a reducing rotor to be selectively configurable in a plurality of different reducing configurations. The different reducing configurations in which the reducing rotor can be configured can include reducing configurations having reducers located at different positions, reducing configurations having different reducer densities (e.g., different overall densities and different regionalized densities), reducer configurations having different reducer counts, reducer configurations having different reducer patterns, and reducer configurations having different lay-outs.

An abrasion wear resistant plate mountable to a rotor of a vertical shaft impact crusher includes a metallic main body, and at least four non-metallic tiles arranged on an upper surface of the main body to form a portion of a contact face facing an internal space of the rotor. Each of the tiles have an abrasion wear resistance greater than that of the main body, each one of the tiles having at least three edges each matching with and positioned against an edge of a neighboring tile.

An apparatus for tearing meat is disclosed. The apparatus includes a gravity-fed hopper including at least one sidewall that forms a first opening configured to receive meat articles and a second opening configured to discharge torn meat articles. The apparatus includes a rotatable spindle element positioned at least partially within the hopper and downstream of the first opening. The rotatable spindle element includes a shaft having a longitudinal axis and a plurality of teeth coupled to the shaft, the teeth being spaced apart from one another. The apparatus includes a plurality of rods, which extend from the sidewall spaced apart from one another and which are interlaced with the plurality of teeth, and a motor coupled to the rotatable spindle element configured to rotate the rotatable spindle element to cause at least some of the plurality of teeth to rotate and pass between two different rods.
