摘要： The invention relates to a method and a device for producing spherical particles from a melted mass of plastic. According to the invention, said melted mass is transformed into droplets by means of a droplet-forming nozzle (10); after falling a certain distance, the droplets are crystallised at least on the surface thereof; the droplets are then supplied to a crystallisation stage in which they are fully crystallised; and are then supplied to an postcondensation stage wherein solid phase polycondensation takes place. In order to ensure surface crystallisation without the risk of adhesion both among the drops and to parts of the device, the drops fall in a crystallisation stage (45) having a cloth element or a sheet metal element comprising openings or a fluidised bed chamber through which gas flows in order to swirl the drops.

摘要： A method for processing a polycondensate to give a granulate formed as pellets is disclosed, whereby the polycondensate is fused in the course of the method and then later resolidified. In an exemplary method, a total time during which the temperature of the polycondensate is above the melting point thereof is less than about 60 seconds. This method can be carried out by a multi-shaft extruder, whereby the degrassing and/or drying of the polycondensate in the solid state occurs at a pressure below atmospheric pressure and/or with addition of an inert gas. The time period, during which the polycondensate remains in the extruder, after being melted therein, amounts to, for example, less than about 15 seconds.

摘要： The invention relates to a method for production of a partly-crystalline polycondensate, in particular, a polyester or a polyamide, whereby a polycondensate prepolymer is firstly produced, which is prepared and formed into granules, by means of a die-face granulating device, with an average diameter of less than 2 mm, said granules being cut at the outlet from the die plate. The degree of crystallisation and the molecular weight are then increased in a solid-phase polycondensation process. For granulation, the polycondensate prepolymer melt is pressed through a die plate with a number of die perforations, preferably arranged on at least one annular track. The cutting is achieved by means of a circulating knife with a liquid jet.
