What does a cryogenic crusher look like?

The complete set of cryogenic pulverizer consists of silo, mechanical pulverizer, induced draft fan, cyclone, vibrating screen, liquid nitrogen tank, etc.:
1. Working principle
The cryogenic pulverizer system uses liquid nitrogen as the cold source. After the material to be crushed is cooled to a brittle and easily pulverized state at low temperature, it enters the mechanical pulverizer cavity and rotates at high speed through the impeller. The crushing effect is achieved under the combined effects of repeated impact, collision, shearing, and friction between materials: the crushed materials are graded and collected by an airflow screen classifier: materials that do not meet the fineness requirements are returned to the silo for continued crushing. , most of the cold air is returned to the silo for recycling:
2. Characteristics
During the material crushing process of this cryogenic crusher system, its cold source forms a closed loop system, which fully utilizes energy and saves energy consumption: the temperature of the cold source for crushing can be reduced to minus 196 degrees. According to the embrittlement of the material The temperature can be adjusted during the crushing process to select the optimal crushing temperature and reduce energy consumption: the crushing fineness can reach 10-700 mesh, or even micron μ and other fineness: liquid nitrogen is used as the grinding medium to achieve ultra-low temperature crushing , comprehensive effects of material explosion-proof, anti-oxidation and so on:
3. Scope of use
Cryogenic crusher system is used for various materials that cannot be crushed at normal temperature. It is widely used in various chemical industries, petrochemicals, machinery, ships, automobile industry, electronics industry, clothing, coatings, printing, engineering plastics, rubber, and thermoplastic materials. , ultra-fine crushing of hot melt materials, nylon, polyester, polyethylene, polypropylene, textiles, clothing, Chinese and Western medicinal materials, food industry and other products:
