Working principle and features:

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

(1) Working principle:

Ultrafine crusher system uses liquid nitrogen as a cold source, and the crushed material is cooled at a low temperature to achieve brittleness. After being crushed, it enters the mechanical crusher chamber and rotates through the impeller at a high speed. The material and blade, tooth plate, materials and materials Reciprocal impacts, collisions, shears, frictions, etc., can achieve the comminution effect: the crushed material is classified and collected by an air flow sieving classifier: the materials that have not reached the fineness requirements are returned to the silo and continue to be crushed. Most of the air-conditioning is returned to the silo for recycling:

(2) Features:

In the process of crushing material, the cryogenic ultrafine crusher system forms a closed circuit circulation system for the cold source to make full use of energy and save energy: the cold source temperature for crushing can be reduced to negative 196 degrees, according to the material's crisp The point temperature, in the process of crushing, its temperature can be controlled, choose a good crushing temperature, reduce energy consumption: crushing fineness can reach 10-700 mesh, even to micron μ fineness: using liquid nitrogen as a grinding medium, ultra-low temperature smash , Explosion-proof materials, anti-oxidation and other comprehensive effects:

2. Use range:

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

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

(5) Smash fineness: 10-1000 mesh (to achieve micrometer μ)

4. Low-temperature crusher complete equipment process configuration:

Liquid nitrogen tank, silo, mechanical crusher, induced draft fan, primary cyclone ejector, air flow rotary screen, automatic feeder:

5. Remarks: Jiake mechanical ultra-low temperature crusher (also known as cryogenic crusher, liquid nitrogen crusher and cryogenic crusher, etc.)
