Abstract:
Device for producing pulverulent plastics with a spherical structure comprises: a container delimiting an interior space, a nozzle device disposed in an upper region of the interior space and connected to a supplying conveyor pipe for a hot melt of the product, wherein the melt exits the nozzle device and separates into small droplets that fall downward in the interior space, a supply unit for a cryogas in a predominantly liquid state having several outlet openings, wherein a cryogas flow, which comes into contact with the small droplets, exits into the interior space. The supply unit is located above or at the same level as the nozzle device, and method wherein, the hot melt of the product exits the nozzle device in the shape of a spray cone, the cryogas flow exits the supply unit in the shape of a cone, and the spray cone is located within the cone.
