Wuhan Green world Technology Co., Ltd has developed the production line technology, which is international advanced for recycling waste tire to fine rubber powder at room temperature. The main equipments are developed itself own. Waste tires and waste rubber can be crushed to 40-200 mesh rubber powder with close, consecutive and automatic process at room temperature without producing harmful emissions, sludge and sewage, so there is no secondary pollution. The investment is only 1/8 of that of cryogenic grinding production line, and the production cost is only 1 / 3 of the latter. The fine powder produced by the technology can be widely used in tire manufacturing, conveyor belt manufacturing, waterproofing membrane, high-grade highway-building.
