ABSTRACT:
An apparatus is provided for concentrating fine or broken particles to separate a particle stream into at least one stream which is concentrated in fine or broken particles and at least one stream with a reduced concentration of fine or broken particles. In addition to introduction and extraction structure, the apparatus includes at least two separator stages each comprising at least one funnel with an inclined or substantially vertical axis which opens upwardly, located beneath an inlet to collect the particles. The funnel is connected to at least one deflector which is directed downwardly to allow particles to flow under gravity and to form a bank of particles at the level of the funnel.
