FIELD: chemical industry; other industries; devices for extrusion and granulation the plastics materials.
SUBSTANCE: the invention is pertaining to the equipment for extrusion and granulation the plastics materials. The spinneret for the granulator of the plastics materials contains the steel body and the working section connected to it. The working section is made in the form of the set of the hard-alloy components with the molding channels. The hard-alloy components are supplied with the reinforcing framings made of the tool steel. The reinforcing framings are rigidly fixed to the spinneret body. The steel body consists of two and more constituent parts. Each part represents the metallic disk with the conical molding channels. The constituent parts differ among themselves by their inlet and outlet diameter of the molding channel. The outlet diameter of the molding channel of one constituent part is equal to the inlet diameter of the molding channel of the following constituent part. The invention allows to vary the diameter of the molding extrusion hole of the spinneret and to increase effectiveness of the granulation process.
EFFECT: the invention allows to vary the diameter of the molding extrusion hole of the spinneret and to increase effectiveness of the granulation process.
