<p>The cylinder which receives the crusher is in two compartments (3, 4) with a selective barrier in between. This only passes products below a given size. The barrier (2) has a circular sieve (10), perpendicular to the axis of the shaft and pierced with divergent holes (11). The compartment after the sieve (4) has a frustoconical central hole (18), with the base pointing towards the sieve. This compartment has spiral blades (17) to compress material on to the cone for finer crushing.</p> |
