The present invention discloses a granular recycled plasticized rubber, which is used in the field of rubber product production. The granular recycled plasticized rubber is prepared by feeding a blend of 20–30 mesh plasticized rubber powder and a softener into the feeding port of a twin-screw main machine, where the twin screws of the twin-screw main machine co-rotate at a speed of 120–160 rpm in an environment below 200°C, and the blend is rolled, sheared and torn in the cavity of the twin-screw main machine, then conveyed to the discharge port. The present invention produces granular recycled plasticized rubber by using a twin-screw extruder with plasticized rubber powder as the raw material for the first time. The granular recycled plasticized rubber has a greatly increased contact area with powdery materials, better bonding performance with powders, and the rubber products prepared therefrom have more stable performance. It can partially or completely replace natural rubber and synthetic rubber to produce various rubber products, has the advantages of energy saving and consumption reduction, low production cost and environmental friendliness, fills the gap in the production of granular recycled plasticized rubber in the industry, achieves huge economic and social benefits, and has a market demand exceeding supply.
