Abstract: The invention relates to a rotor (1) for a reducing machine. According to the invention, the protective caps (6.1) covering the outer plates (3.1) of the rotor (1) are decoupled from the forces of the hammer axles (5) and from the forces exerted directly on the outer protective caps (6.1) by the hammers. The outer protective caps (6.1) which are exposed to the lateral forces of the hammers (4) encompass the outer edge of each of the plates (3.1) with a web (6.2) and encompass each of the inner steps (3.2) of the plate (3.1) with a projection (6.5) in the shape of a ring segment. At the same time, these outer protective caps (3.1) are mounted on the plate (3.1) with a positive fit by means of a connecting element (9) such as a hexagon socket screw. The outer protective caps (3.1) which are adjacent to the inner protective caps (6) are fixed to the outer plate (3.1) with a non-positive fit, also by means of connecting elements (9) such as hexagon socket screws (3.1).

Abstract: In a housing for a comminution machine with tools, which are secured to a rotor supported in the housing and which form active wear parts, such as hammers, and an anvil forming a counter tool, as well as inactive wear parts in the form of interchangeable wear plates which are secured to the rotor and also to the inside of the housing, an opening for feeding the material to be comminuted and at least one grate forming another inactive wear part, an ejection door for discharging heavy parts as well as an impact wall segment facing the ejection door and also forming an inactive wear part, and housing sections which are arranged horizontally in at least one plane, wherein at least one of the housing sections can be pivoted outwards about at least one pivot point, there is provided that at least sections of the wear parts are attached to the housing with bolts secured to the respective wear parts and form zones according to the different wear characteristics of the comminution process, so that the wear parts which

Abstract: The set-up times can be optimized as well as the costs for the production of the individual parts can be decreased with a comminution machine, where the rotor (2) includes active and inactive wear parts (7, 8), of which at least the inactive wear parts (8) are assembled in a composite construction.

Abstract: A rotor shear for comminuting particularly bulky waste materials is formed by two cutting rotors (2) combing each other, disposed parallel to each other, supported in a housing (1), and each driven in an opposite direction. Each cutting rotor (2) comprises spacer rings (4) and rotor disks (5) furnished with cutting teeth (6). A face of a front flank (61) of at least one cutting tooth (6) is furnished with geometrically staggered and/or angled partial faces (65). The spacer rings (4) and the rotor disks (5) are disposed on shafts (3). Wear disks (7) are coordinated to outer rotor disks (5) with corresponding circumferences and are connected to the shaft (3). The cutting teeth (6) operate against the circumference of the spacer rings (4) disposed between the rotor disks (5). At least one support device/stripper device (8) is coordinated with at least one shaft (3), where support parts (81) and stripper parts (82) of the support device/stripper device (8) are functionally separated.

Abstract: A scrap cutter transport unit reduces assembly and dismantling times during production of mass-produced components. The scrap cutter transport unit includes a base frame for accommodating assemblies in both their transportation and operating states. During transportation, the transport unit accommodates a cutter stand in a removed state so that the cutter stand can pivot about a point. A second transport unit is formed by a press frame which includes auxiliary supports for transportation purposes.

Abstract: A method and a device feed and operate a facility, such as a hammer-based crusher, for comminuting recyclable scrap materials, with the scrap material being drawn in with a driven roll and fed to be comminuted as an essentially uniform quantity. Data are collected during the feeding operation and the comminution process for acquiring and controlling operating parameters for feeding the scrap material and for optimizing the operation and the energy efficiency of the comminution process.
