Method and device producing spherical particles from a polymer melt |
| abstract |
The invention relates to a method and a device for the production of spherical particles, whereby a molten prepolymer or precondensate is transformed into droplets by means of a drip nozzle, the droplets are subjected to a countercurrent with a gas in a precipitation column until at least partial crystallization is achieved and are then subjected to an additional post-crystallization phase. In order to economically produce higher quality particles at a high flow rate, the molten prepolymer is transformed into droplets by means of a vibrating nozzle plate and/or direct vibration of the molten prepolymer of polymer and the resulting droplets are subjected to an air and gas countercurrent. |
