<p>The device (10) has a crusher (14) e.g. cone crusher, crushing blocks of material and dividing the material into particles. A separating unit (16) separates the particles, and has a separation chamber (40) having an inlet for particles from the crusher and an outlet (42) for a flow of high grain size particles. An evacuating unit (50) evacuates the air charged with low grain size particles outside the chamber by a charged air outlet (46). The chamber is provided with air inlets (44) distributed around a central vertical axis (X-X`), where the air inlets are distinct from the particles inlet.</p> |
