DRIPPING DEVICE AND METHOD FOR THE OPERATION THEREOF |
摘要 |
A drop pelletizing device and method for producing pellets from a low-viscosity plastic melt are provided. The drop pelletizing device can include a die plate with holes, in which the plastic melt can be subjected to a harmonic pressure oscillation such that the plastic melt emerging from the holes forms individual pellet droplets, a pressure vessel, in which prevails an overpressure above the ambient pressure, a discharge device adapted to discharge the individual pellet droplets from the pressure vessel and to reduce the overpressure, a separator adapted to separate the individual pellet droplets from the coolant; and at least one circulating device adapted to agitate the coolant to separated and unclump the individual pellet droplets in the coolant and for producing turbulence within the coolant. |
