Patent

CA 2229957

The invention relates to a hammer mill or hammer crusher which is provided with two rotors 2, 3 inside the housing 1. The rotors are essentially encircled by grinding paths 13, which are laterally retractable from the housing in an essentially horizontal direction. Provision is thereby made for the section 23 of the grinding path located behind the vertical sectional plane through the rotor axis and projecting upwards from the lowest part of each rotor to be tilted downwards on retraction of the grinding path 13 and thus freeing this part from the rotor. According to the invention, curved flanges 24, 25 are provided on the downwardly tiltable section, which are supported by a counter-support 30.

L'invention porte sur un broyeur ou un concasseur à marteaux qui est muni de deux rotors (2, 3) à l'intérieur d'un bâti (1). Les rotors sont essentiellement entourés par les circuits de broyage (13), qui sont rétractables latéralement à partir du bâti dans une direction essentiellement horizontale. Par ce moyen, la partie (23) du circuit de broyage située derrière le plan de coupe vertical dans l'axe du rotor et faisant saillie vers le haut à partir de la partie la plus basse de chaque rotor peut être inclinée vers le bas lorsque le circuit de broyage (13) est rentré et être ainsi libérée du rotor. D'après l'invention, la partie inclinable vers le bas comporte des rebords incurvés (24, 25) qui sont soutenus par un contre-appui (30).
