In addition, the plastic also contains many recyclable metal components. Analysis showed that the German plastic mill, It discarded plastics. After the physico-chemical treatment. About these can be isolated recycled materials will become a valuable resource for the future of social production, can effectively avoid the depletion of scarce resources 500 plastic mill, while avoiding some heavy metal plastic mill environment. Plastic wastes precious metal. Its taste is typically several times the natural deposits, like recycling costs less than the exploitation of natural deposits. Relying on both sides of the teeth and the parting surface friction wedge job, so to called "wedge toothed belt" is appropriate. Toothed belt wedge having an axial positioning function plastic mill, so the drive is more ambitious than the role of the Division I-sided step belt. Toothed belt and ribbed belt can be successfully applied to plastic mill smw600 plastic mill, the reason lies in the choice of the function of excellent new data layer is very high tensile strength, a small extension of the rate of glass fiber and wire rope ontology layer for induction function excellent neoprene. 500 plastic mill, the sun machinery, plastic mill provided by Helen sun Machinery Manufacturing Co., Ltd., Zhengzhou.
