Die vorliegende Zusatzanmeldung bezieht sich auf die Anwendung vorgenannten Verfahrens zum Herstellen von Schlagplatten für Schlägradmühlen, die gekennzeichnet sind durch Bewehrung mindestens der voreilenden Schlagkante und der unmittelbar anschließenden Flächen.The present additional application relates to the application mentioned above Process for the production of beater plates for Schlägradmühle, which is characterized are reinforced by at least the leading edge and the immediately adjoining surfaces.

Die Erfindung ist in beiliegender Abbildung schematisch dargestellt und im folgenden näher erläutert. Es bedeutet 170 eine erfindungsgemäß ausgeführte Schlagplatte einer Schlagradmühle oder dergl., mit voreilender Schlagkante 171, die bevorzugt verschleißt. Es ist ein winkelförmiger Träger aus Lochblech mit genügendem seitlichen Abstand vorgesehen, auf dem eine oder mehrere Reihen von Hartstoffteilchen 173 befestigt sind. Die Mahlgutteilchen 174 schlagen im Betrieb auf die bewehrten Flächen in der Nähe derThe invention is shown schematically in the accompanying figure and explained in more detail below. 170 means an inventive beater plate of a beater mill or the like, with a leading beater edge 171, which preferentially wears out. It's an angular beam made of perforated plate provided with sufficient lateral spacing, on which one or more rows of hard material particles 173 are attached.
