1、 Working principle and characteristics

The complete set of cryogenic crusher for this product consists of a silo, mechanical crusher, induced draft fan, cyclone, liquid nitrogen tank, etc.

（1）Working principle

The cryogenic crusher system uses liquid nitrogen as the cold source. After the crushed material is cooled at low temperature to achieve a brittle and easily crushed state, it enters the mechanical crusher chamber and rotates at high speed through the impeller. Under the comprehensive effects of repeated impacts, collisions, shearing, friction, etc. between the material and the blades, teeth, and materials, the crushing effect is achieved. Most of the cold air is returned to the silo for recycling.

（2）Characteristics

During the material crushing process, the cryogenic crusher system forms a closed-loop circulation system with its cold source, which fully utilizes energy and saves energy consumption: the temperature of the cold source used for crushing can be reduced to minus zero196Degree, according to the brittle point temperature of the material, its temperature can be adjusted during the crushing process, and the optimal crushing temperature can be selected to reduce energy consumption: the crushing fineness can reach10-600Aim, even up to micrometer fineness: using liquid nitrogen as the grinding medium, achieve comprehensive effects such as ultra-low temperature crushing, material explosion prevention, and oxidation prevention.

2、 Scope of use

This cryogenic crusher system is used for various materials that cannot be crushed at room temperature and is widely used in the following fields:

1Chemical and coating fields:

In the field of metal wall coatings, adhesive coatings and high bonding coatings; Silent coating: elastomer, nano sound-absorbing coating; Ultra fine grinding of functional masterbatch, coloring and extraction masterbatch, pigment dyes, thermoplastic elastomers, engineering plastics, and other products.

2In the field of food and health products:

The crushing of plant fruits, animal and plant extracts, traditional Chinese patent medicines and simple preparations, natural and synthetic elements can ensure that their original elements will not be lost during the crushing and drying process.

3Biotechnology industry:

Crushing active cells, crushing spores, saponins, Proteins, vitamins, etc.

4In the field of plastic recycling:

Low temperature crushing method for low melting point plastics, high self-lubricating materials, waste rubber, and raw rubber.

5For high water content products, such as animal and plant extracts, traditional Chinese patent medicines and simple preparations, synthetic fiber, seaweed extracts, etc; Crush special materials such as strong fibrous materials, animal placenta extract, honeycomb, and body fluids.
