| titleOfInvention | Crushing element and mills with grinding bodies, mixers, extruders and a pressing worm provided with said crushing elements |
| abstract | The invention relates to a crushing element for mills, mixtures and worms used, preferably, for grinding and treating paper pulp and plastic materials containing ceramic fillings and other fibrous materials such as raw lignite, beet chips and the similar. The crushing elements comprise at least two fixing elements which can be provided with undercuts (44), beads and/or corners and arranged on a fastening side (36) opposite to a working surface (38) for fixing the crushing element (41) in corresponding holes of a supporting part. Said crushing elements are mountable on the rotors of high-speed refiners. The rotors comprise annular sectors consisting of a plurality of individuals crushing elements. Different tasks are assigned to said annular sectors. A middle sector is made of metal carbides which are tenaciously embedded in such a way they are fixed, high-temperature resistant and exhibit emergency running properties when a rubbing of a grinding disk occurs. In order to provided a slightly smaller working space in the area of said sector, the adjacent sectors are protected against rubbing and are formed by the modular and low-cost crushing elements (lamellar bodies) made of a ceramic material or compressed carbon fibres. Said lamellar bodies are obtainable by the accurate serial production (PIM-powder injection moulding) and compression in a sieve-like supporting plate are optimally shaped for each user. The lamellar bodies are easily and rapidly interchangeable. |
