(1) Working principle:
The low-temperature crusher system of Chinese medicinal materials takes liquid nitrogen as the cold source, and the crushed materials are cooled to complete the brittle and fragile state at low temperature. After entering the mechanical crusher chamber, the crushed materials are rotated by impellers at high speed, and the materials and blades, gear discs, materials and materials are repeatedly impacted, collided, sheared and frictionally. It achieves the crushing effect: the crushed materials have airflow. The sieve classifier stops classifying and collecting: the material which has not reached the request of fineness returns to the silo to continue to crush, and most of the air-conditioning returns to the silo for recycling:
In the process of material crushing, the cold source of cell wall-breaking freezing crusher system constitutes a closed-circuit circulating system, which makes energy abundant application and saves energy consumption: the temperature of cold source for crushing can be reduced to minus 196 degrees. According to the temperature of material's brittle point, the temperature can be adjusted in the process of crushing, and the optimum crushing temperature can be selected to reduce energy consumption: the fineness of crushing can reach 10-700 meshes, and even reach minus 196 degrees. Reaching micron-mu and other fineness: using liquid nitrogen as grinding medium to complete the comprehensive effects of ultra-low temperature grinding, explosion-proof and oxidation-proof of materials:
2. Scope of application:
The cryogenic crusher system is applied to all kinds of materials that can not be crushed at room temperature. It is widely used in ultra-fine crushing of chemical, petrochemical, mechanical, shipping, automotive, electronics, clothing, coatings, printing, engineering plastics, rubber, thermoplastic materials, food and exercise industries (pepper powder, pepper powder, etc.), Chinese and Western medicines, etc.
