In industrialized countries, subsidies for waste rubber handle 60 mesh rubber powder, so you can use liquid nitrogen cooling air expansion method and grinding method. The developing countries and countries unsubsidized production of powder should be used at room temperature in order to adapt to the market and to achieve better economic results. The main powder by freeze crushing method and grinding method at room temperature to produce. Freeze grinding process produces frozen ground, there are two: one is the cryogenic grinding process. Another is the use of low temperature and room temperature and grinding process. The former is the use of liquid nitrogen as a cooling medium. After making cryogenic waste rubber hammer mill or roller mill cryogenic grinding. Fine rubber powder production line that is manufactured using the latter method. The use of liquid nitrogen cryogenic technology to process waste tires into more than 80 mesh fine rubber powder, its production process temperature, speed, overload are closed-loop computer control chain, environmental pollution. The whole production process of the production line are used in compressed air-driven feeder and closed pipeline Shandong yechon Group covers an area 30,000 square meters 40 mesh rubber powder, the registered capital of 30 million yuan, employees 102 people sbs rubber powder, which professional engineers, professional and technical production staff of 26 people, six machine repair technicians. Workshop has 19,722 square meters, including 10,000 square meters of production workshop, office area 1000 square meters, 8000 square meters warehouse, machine repair workshop and laboratories, power distribution room and a total of more than 170 square meters. The company's construction follows from the "starting point, high quality, economies of scale" of the construction principles rubber powder, to ensure the quality of the premise, to achieve the environmental objectives. The company has two production plants, divided into ordinary workshop and tire crumb rubber powder workshop. Powder production process: feed - Broken - ingredients - grated - test - packaging - shipping. Part of the dust generated in the production process, we took a whirlwind odor bag type dust collecting equipment and activated carbon filters, mist spray odor. 40 mesh rubber powder _ yechon Group Quality First (certified) _ rubber powder provided by Shandong yechon Group Limited.
