Abstract

An apparatus for preventing the spread of small particles into the ambient surroundings in the granulation of plastics includes a cyclone. In the cyclone (3), there is disposed a dust separator (11) with a separator chamber (18) with a deflector device (19). The separator chamber (18) is disposed between the lower outlet (12) of the cyclone for the particles and an inlet conduit (13) for air. In the separator chamber (18), air flows through a curtain of falling particles where fine dust is entrained upwards by the air, while larger particles depart to a subjacent discharge sluice (10) for the granulate. The cyclone (3) has a conduit (16) which extends far down in the conical section (17) of the cyclone so that dust separated in the dust separator chamber (18) may depart via the conduit (16).
