摘要

A device for cooling bulk material by low-boiling liquefied gas includes a precooling zone and a spraying zone. The precooling zone is inclined from the horizontal downwardly toward its discharge end to which is attached a rotatable drum-shaped chamber as its spraying and draining zone which is constructed as a worm conveyor. Where used for scrap tires, a spray pipe is provided at the discharge end with a ring mounted on the internal wall between the spray orifices and the discharge opening, the ring having a thickness corresponding to the average tire thickness.
