Abstract

The present invention generally relates to a feeder for particulate material such as particulate polymer waste. More particularly, the present invention relates to an extrusion device including the feeder for improved extrusion of materials such as particulate polymer waste which effectively changes the quality and characteristics/properties of the polymer waste to, for example, create commercially useful products such as, for example, devulcanised rubber powders or composite materials. In a specific embodiment the method includes the steps of (1) storing one or more batches of waste polymer in one or more respective hoppers, (2) regulating the flow of waste polymer supplied to a conveyor from the one or more hoppers, (3) transporting the waste polymer from the one or more hoppers and along the one or more conveyors to an extruder such that at least some interstitial air is expelled from the waste polymer, (4) feeding the waste polymer from the one or more conveyors to an extruder, and (5) passing the waste polymer through the extruder to provide a pulverised activated and devulcanised polymer product. The present invention is particularly useful for the processing of tyres including tyre segments or shredded tyre waste.
