<p>PROBLEM TO BE SOLVED: To make it possible to reuse a recovered waste plastic material by melting it. SOLUTION: Thie device for regenerating a waste plastic material reuses a waste plastic material by supplying the shreddings of the recovered waste plastic material into a chamber 3, then stirring them with the help of a stirring blade 5 which is maintained at a low temperature level by circulating a coolant through a hollow rotary shaft 5a and melting the waste plastic material by a frictional heat generated by the stirring action. To put this method into practice, the stirring blade 5 with the hollow rotary shaft 5a is provided, in a freely rapidly rotating manner, in the chamber 3 connected to a feed aperture 18, through which the waste plastic material is fed, and a circulating path 8 for supplying and draining the coolant is connected to the hollow part of the rotary shaft 5a.</p> |
