ABSTRACT:
The ultracentrifugal disintegrator includes a device for cooling the annular zone (7), extending from the outer face (8) of the rotor (4) to the inner face (9) of the sieve (5), by feeding a gaseous coolant to the upper part of the zone (7), vertically with respect to the zone (7). Such a disintegrator is used for the cryocomminution of heat sensitive material.
