  • the overflow of the hydrocyclone is then already well conditioned for further processing.
  • further processing steps may be followed by a flotation, a magnetic separation or the like. This good Conditioning takes place taking into account the fact that the otherwise desired maximum thickening does not have the highest priority in the lower reaches during operation.

Abstract

L'invention concerne un procédé de préparation par voie humide de matériaux, tels que des minerais ou matières similaires, au moyen d'un processus de broyage en circuit dans une cuve de broyage et de classification de la boue de matière broyée par l'intermédiaire d'au moins un hydrocyclone qui se décharge dans l'alimentation du broyeur. Selon l'invention, la matière grossière accumulée à la sortie inférieure de l'hydrocyclone arrive, après une première classification par cyclone, sur un dispositif de criblage pour subir une deuxième classification, la matière fine criblée étant séparée et seule la matière grossière restante étant réintroduite dans le circuit de broyage, ce dernier étant de ce fait délesté.
