  Mahlwalze für Schrot- und Mahlmühlen. 



   Es ist bekannt, die Mahlwalze für kleinere Schrotmühlen aus einem einzigen Stück durch
Umgiessen eines Kernes herzustellen. Gemäss der Erfindung werden hierbei die Luftfurchen in   der Mahlwalze dadurch gebildet. dass in den Kunsteinmantel dünne Holzstreifen miteingegossen werden, die nach Erstarren des Steinkörpers entfernt werden und in der Mantelfläche die ge-     wünschten Luftfurchen ergeben. Diebe   können in   Schraubenwindungen   oder axial verlaufen. 



   In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt.

  Grinding roller for grist and grinding mills.



   It is known to make the grinding roller for smaller grist mills from a single piece
To produce casting around a core. According to the invention, the air furrows are thereby formed in the grinding roller. that thin strips of wood are cast into the artificial casing, which are removed after the stone body has solidified and result in the desired air grooves in the casing surface. Thieves can run in helical turns or axially.



   The subject matter of the invention is shown in the drawing, for example.



   Fig. I shows a view. FIG. 2 shows an end view, FIG. 3 shows a central section through a
Grinding drum.



   The core a of the drum is equipped on its circumference with appropriate depressions of any kind, in which the stone material to be encased is bedding and a solid one
