Abstract
An apparatus and method for the pelletization of waxes, wax-like and other materials having a sharp melt point include a vessel for forming the wax into a hot molten material. A heat exchanger then cools the molten wax to a temperature just above its melt temperature. The cooled liquid wax is fed to an extruder which further reduces the temperature and mixes the liquid wax into a thoroughly mixed extrudable solid wax. The solid wax is then extruded through die orifices of a die plate into a cutting chamber, and a rotary cutter cooperating with the die face of the die plate cuts the extruded solid wax strands into pellets. The die plate, cutting chamber and rotary cutter can have the same structure as an underwater pelletizer, but operating without water or liquid as a dry face pelletizer. The thus formed wax pellets drop out of the cutting chamber by gravity through an opening in the bottom thereof.
