Working principle and features:

Refrigerated cryogenic crusher consists of silos, mechanical crushers, induced draft fans, cyclones, vibrating screens, automatic feeders, liquid nitrogen tanks, etc.:

(1) Working principle:

The deep-frozen liquid nitrogen disintegrator system uses liquid nitrogen as a cold source, and the crushed material is cooled at a low temperature to achieve embrittlement. After being crushed, it enters the mechanical crusher chamber and rotates through the impeller at high speed. The material and the blade, the tooth plate, and the material Repeated impacts, collisions, shears, and frictions between the materials achieve the comminution effect: the crushed material is classified and collected by an air sifting grading machine: materials that have not reached the fineness requirements are returned to the hopper and continue to be crushed. Most of the air-conditioners return to the silo for recycling:

(2) Features:

During the crushing process of the cryogenic liquid nitrogen pulverizer system, the cold source forms a closed circuit circulation system to make full use of energy and save energy: the temperature of the cold source for crushing can be reduced to negative 196 degrees, according to the point of material embrittlement Temperature, in the crushing process, its temperature can be controlled, select the best crushing temperature, reduce energy consumption: crushing fineness can reach 10-700 mesh, even to micron μ fineness: use liquid nitrogen as grinding media, achieve ultra-low temperature crushing, materials Explosion-proof, anti-oxidation and other comprehensive effects:

2. Use range:

The cryogenic crusher system is used in various materials that cannot be crushed at room temperature and is widely used in various chemical, petrochemical, mechanical, marine, automotive, electronics, clothing, coatings, printing, engineering plastics, rubber, thermoplastic materials , ultra-fine grinding of the food industry (chili powder, pepper, etc.), Chinese and Western medicines, etc.:

3. The main technical parameters:

(1) Crusher Studio Diameter φ250mm

(2) Crusher power: 7.5KW

(3) Working medium: liquid nitrogen

(4), working temperature: 0 degrees to negative 197 degrees
