GRANULATOR FOR CROSS-LINKABLE PLASTIC

摘要

A granulator for forming granules of cross-linkable plastic compounds in which a screw extruder extrudes the compound into the smaller diameter end of a funnel-shaped, annular conduit, the other end of the conduit facing a die with circular arrays of through-holes. The compound which passes through the throughholes is cut into granules by rotating blades having air nozzles which remove particles of the compound from the blades. The granules are received in a chamber from which they are removed pneumatically. Where the annular conduit meets the die, there are channels within and outside of the arrays of through-holes which lead to the outside of the granulator and which provide conduits for removal of compound which does not directly impinge on the entrances of the through-holes which are specially shaped to avoid accumulation of the compound between the throughholes.
