Abstract
(DE)
Die Erfindung betrifft Mahlkörper (20) zur Verwendung in einer elektromechanischen Zerkleinerungsanlage sowie eine entsprechende Vorrichtung und ein Verfahren zur Herstellung solcher Mahlkörper (20). Dabei werden Mahlkörper (20) mit geringem Mahlkörperverschleiß und großer Produktverträglichkeit bereitgestellt, die entsprechende magnetische und mechanische Eigenschaften aufweisen. Solche Mahlkörper weisen einen hartmagnetischen Kern (6) und wenigstens eine diesen umgebende verschleißfeste Beschichtung (28) auf. Solche beschichteten, hartmagnetischen Mahlkörper (20) sind in Mahlanlagen zur Zerkleinerung, Deagglomeration und/oder Dispergierung insbesondere von Substanzen einsetzbar, die in der Pharmazie, Biotechnologie und/oder Lebensmittelindustrie benötigt werden.
(EN)
The invention relates to grinding media (20) for use in an electromechanical comminution plant and a corresponding device and a method for production of such grinding media (20). According to the invention, grinding media (20) having low grinding media wear and high product compatibility, which have corresponding magnetic and mechanical properties, are provided. Such grinding media have a magnetically hard core (6) and at least one wear-resistant coating (28) surrounding said core. According to the invention, such coated, magnetically hard grinding media (20) can be used in grinding plants for comminution, de-agglomeration and/or dispersion, in particular of substances which are required in the pharmaceutical, biotechnology and/or food industry.

L’invention concerne un corps broyant (20) destiné à être utilisé dans une installation de broyage électromécanique ainsi qu’un dispositif correspondant et un procédé de fabrication d’un tel corps broyant (20). Selon l’invention, des corps broyants (20) sont prévus présentant une usure de corps broyant réduite et une bonne compatibilité des produits, lesquels corps broyants présentent des propriétés magnétiques et mécaniques correspondantes. De tels corps broyants présentent un noyau (6) à magnétisme dur et au moins un revêtement (28) résistant à l’usure entourant ce noyau. De tels corps broyants (20) à magnétisme dur revêtus peuvent être utilisés dans des broyeurs pour le broyage, la désagrégation et/ou la dispersion de substances en particulier, qui sont nécessaires dans les domaines pharmaceutique, de la biotechnologie et/ou dans l’industrie alimentaire.
