Nowadays, low-temperature crushers are widely used in various industries of social production, but their development is quite rapid. Today, Yanyi Machinery, which has become the technical representative of China's crusher industry, will bring you an introduction to low-temperature crushers. Becoming an important member of the national economic production and construction. Although this technology started relatively late in China's development,
The introduction of foreign technology and equipment not only requires a large amount of capital, but also due to different national conditions, such as different waste treatment costs and liquid nitrogen costs, even after the introduction of foreign equipment, it may not be feasible in terms of operating costs. Different degrees of adjustment are needed in the process route and equipment selection. The research on low-temperature crushing of waste circuit boards in China has just begun. Therefore, it is necessary and meaningful to conduct research on low-temperature crushing technology. Yanyi Machinery focuses on comparing the cumulative yield, morphology, dissociation degree, and energy consumption of samples under different low-temperature conditions, and studying the effect of low-temperature crushing of circuit boards.
Working principle: The low-temperature crusher system uses liquid nitrogen as the cold source, which becomes an easily crushable state. After entering the mechanical crusher chamber, the impeller rotates at high speed, and the crushed material is cooled by the cooling system at low temperature to achieve material embrittlement. The comprehensive effects of repeated impact and friction between materials, blades, teeth, and materials achieve the crushing effect. Materials that do not meet the fineness requirements are returned to the material bin for further crushing. The crushed materials are classified and collected by an air flow sieve classifier, and most of the low-temperature cold air generated is returned to the material bin for recycling.
Low temperature crushing technology assists the development of the pharmaceutical industry:
Industry adaptation: Suitable for various materials that cannot be crushed at room temperature, widely used in low-temperature crushing of various chemical, nylon, polyester, polypropylene, polyethylene, food, petrochemical, metallurgical, automotive industries, electronics, clothing, coatings, printing, plastics, rubber, thermoplastic materials, hot melt adhesives, traditional Chinese and Western medicine and other products.
