Working principle and characteristics of automatic cryogenic plastic mill:
The whole set of ultra-cold shredder is composed of silo, mechanical shredder, induced draft fan, cyclone, vibrating screen, liquid nitrogen tank and so on.
(1) Working principle of the mill: This ultra-cold pulverizer system uses liquid nitrogen as a cold source. After the pulverized material is cooled to achieve embrittlement and pulverization at low temperature, it enters the cavity of the mechanical pulverizer and rotates at high speed through the impeller. Reciprocating impacts, collisions, shearing, friction, etc. with blades, gears, materials and materials can achieve the crushing effect: the crushed materials are classified and collected by an airflow classifier: the fineness is not reached The required materials are returned to the bin to continue crushing, and most of the cold air is returned to the bin for recycling.
(2) Features: During the material pulverization process of the ultra-cold pulverizer system, its cold source forms a closed-loop circulation system to make full use of energy and save energy consumption: the temperature of the cold source for pulverization can be reduced to minus 196 degrees, according to The brittle point temperature of the material can be adjusted during the pulverization process. Select an appropriate pulverization temperature to reduce energy consumption: the pulverization fineness can reach 10-700 mesh, even micron μ and other fineness: use liquid nitrogen as the grinding medium, Achieve the comprehensive effects of ultra-low temperature crushing, explosion-proof and anti-oxidation of materials.
- Scope of application: This ultra-cold pulverizer system is used for various materials that cannot be pulverized at room temperature, and is widely used in various chemical, petrochemical, machinery, ship, automotive industries, electronics industries, clothing, coatings, printing, engineering plastics , Rubber, thermoplastic materials, hot melt adhesives, nylon, polyester, polypropylene, polyethylene, food industry (chilli powder), Chinese and Western medicinal materials, etc.
