METHOD OF OPERATING A TEMPERATURE-CONTROLLED THERMOKINETIC MIXER FOR REGENERATING VULCANIZED RUBBER

摘要

A method of operating a temperature-controlled K-mixer for thermally and kinetically regenerating vulcanized crumb rubber is provided. The K-mixer includes a chamber and a shaft provided with a plurality of blades. The method includes the steps of inserting a mixture of vulcanized crumb rubber and a lubricant in the chamber of the K-mixer; heating the mixture by rotating the shaft of the K-mixer until the temperature of the mixture has reached a devulcanizing or regeneration temperature; cooling the mixture by reducing the rotational speed of the K-mixer and by circulating a cooling fluid in the shaft and in channels of the blades.

1. A method of operating a temperature-controlled K-mixer for thermally and kinetically regenerating vulcanized crumb rubber, said K-mixer including a chamber and a shaft provided with a plurality of blades, the method comprising the steps of:
inserting a mixture of vulcanized crumb rubber and a lubricant in the chamber of the K-mixer; heating the mixture by rotating the shaft of the K-mixer until the temperature of the mixture has reached a devulcanizing temperature; cooling the mixture by reducing the rotational speed of the K-mixer and by circulating a cooling fluid in the shaft and in channels of the blades; and recovering regenerated crumb rubber from the chamber.
