Method and apparatus for recycling waste PBT using compounding technology

摘要

The present invention relates to a recycling method and a recycling device of waste poly-butylene-terephthalate (PBT) using a compounding technology. The recycling method of the PBT comprises the steps of continuously pulverizing the waste PBT after crushing the waste PBT; measuring the pulverized PBT introduced in a drying machine, setting drying conditions and drying the pulverized PBT with hot air and moisture absorption; compounding in which the dried waste PBT is mixed with additives; and removing and extruding steam generated in a manufacturing process while turning the compounded mixture into pellets.
