Abstract

Cette machine est du type comprenant un rotor (5) tournant à l'intérieur d'un bâti (11) auquel sont associées une goulotte (34) d'alimentation en produits à broyer et une goulotte (16) d'évacuation des produits broyés. This machine is of the type comprising a rotor (5) rotating inside a frame (11) with which is associated a feed chute (34) for grinding products and a chute (16) for evacuating the crushed products.

Le problème à résoudre consiste, entre autres, à réduire la consommation d'énergie, tout en traitant des pièces de grande dimension. The problem to be resolved consists, among other things, in reducing energy consumption while processing parts of large dimension.

Suivant l'invention, la goulotte d'alimentation (34) pré­ sente un fond plan (35) évidé et le bâti présente tangentielle­ ment au rotor et de part et d'autre de la zone de tangence un premier plateau plein (23) contre lequel ledit fond (35) est monté coulissant et un second plateau plein décalé et délimitant avec celui-ci une ouverture d'alimentation (29) tandis que le second plateau (24) porte un poussoir (37) pouvant obturer cette ouverture (29). According to the invention, the feed chute (34) pre feels a flat bottom (35) hollowed out and the frame has tangential ment to the rotor and on either side of the tangency zone a first full plate (23) against which said bottom (35) is sliding mounted and a second offset full tray and defining therewith a feed opening (29) while the second plate (24) carries a pusher (37) can close this opening (29).

L'invention trouve une application avantageuse sur la machine de broyage de pièces en matière plastique. The invention finds an advantageous application on the machine for grinding plastic parts.
