Abstract
For crushing rock or the like, use is made of an impact mill which contains in an approximately annular housing a rotor (2) having an axial entry orifice. The rotor (2) has a baseplate with a central impact plate (7), a cover plate with a central recess and, between the baseplate and cover plate, blades (11) which form ejection orifices (16) and which are each equipped with a pocket (17) for receiving crushed material. The ejection side of each pocket (17) is equipped with an exchangeable wearing part which is fastened to the blade (11) and which is composed of a carrier body (12) and of a carbide strip (13). The inner face of the pocket (17) on the ejection side is formed by a face (20) of the carbide strip (13) and extends approximately perpendicularly relative to a contact plane (B) of the edges of the pocket (17). The carbide strip (13) has a wearing face (21) in the form of an arc of a circle and projects with the outer edge beyond the rotor circumference. The inner face of the carrier body (12) and the inner face (20) of the carbide strip (13) form an angle of 95 DEG to 110 DEG and extend symmetrically relative to a radius of the rotor (2). <IMAGE>
