Scheer underwater pelletizing
with divertor valve and melt pump |
Extrudate leaving the die plate is cut into pellets in the pelletizing chamber, which is completely filled with process water. Through the high temperature differential between their melting point and the temperature of the water, the pieces of cut polymer solidify instantly. The spherical or lentoid shape, typical for this pelletising technology, arises as a product of the polymer viscosity. |
