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, 4.7) are provided in the region of the housing (2.1) for ejecting coarse, heavy or hard parts.

A method and a briquetting press for briquetting metal chips, wherein stable briquettes/pressed component are produced. The actual length (Lact) of the pressed component is obtained by applying pressure (Pmax/Preq) using at least one pressing ram (1, 2) and measuring the length with a measuring device (5, 6). The measured value is compared to a desired nominal value (Lnom) and a difference value (□) is subsequently determined.

摘要:
The invention relates to a method and to a shearing and compacting press for the production of pressed parts, preferably packages (20) from waste material, especially scrap and sheet clippings. The material used is pre-compacted in a first compacting step. In a second compacting step, the material, which has been pre-compacted to the width of the package, is subjected to intermediate compacting until the height of the package (20) is reached. In a third compacting step, final compacting of the material to the final width or length of the package (20) is carried out. According to the invention, the material is pre-compacted with a continuos force and optionally sheared until the compressor (3.1) reaches its final position. The compressor (3.2) is securely adjusted and guided to its end position on a parallel plane. Subsequently, the compressor (3.3) is guided in a position in which the compressor (3.1) releases the opening of the package chamber (2.3) when the compressor (3.1) is driven back. Finally, the compressor (3.1, 3.2, 3.3) is subjected to a pressure that is lower than the maximum pressure available in the compressors (3.1, 3.2, 3.3) at the beginning of the working and return strokes. The compressor (3.1) is subjected to maximum pressure for shearing and/or the compressors (3.2, 3.3) are supplied with maximum pressure to end pressing. The invention is also characterized in that the pressing pressure for the compressors (3.1, 3.2, 3.3) is gradually controlled depending on the degree of compression or the corresponding length.

The invention relates to a press for processing, such as pressing and/or shearing, any type of material (3), particularly scrap metal or metal wastes, comprising: a bed (1) for filling and strand-like compacting and feeding this material (3); a downward-located column (2) having at least one stamper (2.2), which is guided inside the column while being driven by a second hydraulic cylinder (2.2.2) attached to a crosshead (2.1) of the column (2); at least one third hydraulic cylinder (2.4.2), and; a hydraulic control (5) provided with a control block (7) and pipes (6). This press should, in order to increase its overall efficiency, improve the feeding/loading of the material (3) to be processed, ensure a largely coordinated execution of the functional steps, optimize the kinematic sequence of the functional elements and the expenditure of energy therefor, have a reduced loading height and bed length, check the state of wear and monitor the operating state both of the kinematic sequences as well as of the hydraulic system while making them visible to the press operator whereby, all in all, increasing the availability of the press, the intensity of the processing of the material (3) and the output quota thereof from the press.
