A striking tool for crushing metal or stone materials, where the striking tool is manufactured from an iron-based material and includes a bearing section, into which a bearing opening is formed around a pivot axis and includes a striking section which is exposed to a striking load by contact with the material to be crushed, and a rotor equipped therewith for a machine to crush metal or stone materials. The striking tool improves with the ability of its bearing section to absorb the dynamic loads acting on the striking tool. The bearing opening has a support section, on whose inner circumferential surface the striking tool is mounted for its swing movement around the pivot axis and has an extension section, which is connected to the support section and the bearing opening is extended in the direction of the striking section with respect to the support section.

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 crusher having a substantially tubular casing, closed in an upper region by a cover and in a lower region by a base. The crusher also includes a rotating shaft, which is internal and coaxial to the casing, with multiple supporting elements, each element for supporting a number of crushing elements, being keyed to the shaft. The crushing elements have circular trajectories with a circumference that at least partially increases from the upper region toward the lower region of the crusher.

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.
