A striking tool for crushing metal objects or stone materials, manufactured from an iron-based material and including a bearing section, into which a bearing opening provided for the freely swinging mounting of the striking tool on a metallic shaft is formed with an inner circumferential surface surrounding the bearing opening, and including a striking section, which is exposed to a striking load by contact with the material to be crushed, and a rotor for a machine for crushing metal objects or stone materials, including at least one metallic shaft, on which at least one formed striking tool is mounted with its bearing opening, with there being metallic frictional contact between the outer circumferential surface of the shaft and the inner circumferential surface of the bearing opening of the striking tool. The striking tool allows, the danger of excess wear in the region of its bearing opening to be minimized.

Certain aspects of the technology disclosed herein include an apparatus and method for forming nanoparticles. The method includes a mechanical milling process induced by aerodynamic, centrifugal, and centripetal forces and further augmented by ultrasound, magnetic pulse, and high voltage impact. A nanoparticle mill having an atmospheric and luminance controlled environment can form precisely calibrated nanoparticles. A nanoparticle mill can include first aerodynamic vane configured to rotate around a central axis of the nanoparticle mill in a first direction, and a second aerodynamic vane configured to rotate around the central axis in a second direction. An aerodynamic shape of an aerodynamic vane can be configured to cause particles within the nanoparticle mill to flow around the aerodynamic vane. The nanoparticle mill can include a primary product line, a nanoparticle sampling line, a particle programming array, a solidifying chamber, or any combination thereof.

A crusher includes a housing having an inlet and an outlet at opposite axial sides, an impeller positioned proximate the inlet of the housing, a shaft connected to the impeller and extending axially through the housing between the inlet and the outlet, at least two spaced apart support structures holding the shaft in the housing, a plurality of dynamic blades extending outwardly from the shaft, and a plurality of fixed blades extending radially inward from an inner wall of the housing and alternatingly positioned between the dynamic blades.

The present disclosure relates to a hierarchical wear part including a reinforced portion comprising zirconia or an alumina-zirconia alloy. The reinforced portion also includes centimetric inserts with a predefined geometry. The inserts include micrometric particles of metal carbides, nitrides, borides, or intermetallic compounds bonded by a first metal matrix. The inserts are inserted into a reinforcement structure infiltrated by a second metal matrix, the reinforcement structure having a periodic alternation of millimetric areas of high and low concentration of micrometric particles of zirconia or alumina-zirconia alloy. The second metal matrix is different from the first metal matrix.
