Abstract: A method and an installation for operating a system for comminuting scrap material is provided. The installation includes a supply device (1) for the scrap material to be comminuted, and a comminuting machine (2) with at least one motor-driven (2.3) rotor (2.2) which has comminuting tools (2.2.1) and is horizontally positioned in a housing (2.1) and has an ejection door (2.1.1). The inventive installation also includes drive means for controlling the power and for protecting the installation from scrap material which is difficult to comminute or which cannot be comminuted at all, such as coarse, heavy or hard parts. For optimizing the comminuting process, the values of the motor output, of the rotation speed of the rotor, of the temperature of the motor and the motor bearings and/or of the height of the scrap material flow (3) supplied to the comminuting machine (2), are inputted in a controller (4) and used to control/regulate the scrap material supply. Technical means (4.5, 4.6, 4.

Abstract: The invention provides a method and an arrangement for operating a system for comminuting scrap material. The installation includes a supply device (1) for the scrap material to be comminuted, and a comminuting machine (2) with at least one motor-driven (2.3) rotor (2.2) which has comminuting tools (2.2.1) and is horizontally positioned in a housing (2.1) and has an ejection door (2.1.1). The inventive installation also includes drive means for controlling the power and for protecting the installation from scrap material which is difficult to comminute or which cannot be comminuted at all, such as coarse, heavy or hard parts. In order to optimize the comminuting process, the values of the motor output, of the rotation speed of the rotor, of the temperature of the motor and the motor bearings and/or of the height of the scrap material flow (3) supplied to the comminuting machine (2), are inputted in a control device (4) and used to control/regulate the scrap material supply.

Abstract: To operate the air circulation and convey the stock flow of scrap material comminuted in the housing (1) of a hammer mill, the airflow generated by the blower effect of a rotor (2) and the stock flow passing through an upper classifying grate (4) are diverted by a deflector hood (8) and guided vertically downwards into a duct (6) that is separate from the housing (1). The stock flow is combined with the stock flow classified in the area of a lower classifying grate (5). The air flow is then guided in the circulating air and the combined stock flow is conveyed to a device (11) for further processing, sorting and/or conveyance.

Abstract: The invention relates to a device for loading a fragmenting machine, such as a hammer crusher, including a front and rear upper drive roller which are equipped, independently of each other, with a drive mechanism and arranged above the feed plane of a feed chute. The drive rollers are mounted on a displaceable and pressure exerting system of levers, such that a continuous, pre-pressed and controlled feed of recyclable material for fragmenting is guaranteed.

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).
