1、 Working principle

The complete set of cryogenic crusher for this product consists of a silo, mechanical crusher, induced draft fan, cyclone, vibrating screen, liquid nitrogen tank, etc.
The cryogenic crusher system uses liquid nitrogen as the cold source. The material is cooled at low temperature toAfter embrittlement, it is crushed between the grinding disc and the tooth plate through a combination of collision, shear, friction, and other actions, while most of the liquid nitrogen cold air continues to be returned to the silo for recycling.

2、 Performance advantages

• Temperature controllable: Low temperature can reach -196 degrees Celsius

• Convenient adjustment of product fineness: adjustable between 50-500 mesh

• Recycling: Liquid nitrogen is used as a cooling medium for materials and is recycled,Realize ultra-low temperature crushing

• Explosion proof and oxidation resistant effect is significant

2、 Scope of use
The cryogenic crusher is very suitable for materials that cannot be crushed at room temperature and is widely used in the following fields:
1. Chemical and coating fields:
Metal wall coating field: powders for PTFE, PA, PC, PU, PP, PE coatings;

Adhesive coating, high bonding coating:Silent coating: elastomer, nano sound-absorbing coating;

Anti corrosion coating; The raw materials used for absorbing coatings are finely ground. Low density polyethylene (LDPE), clothing hot melt adhesive, polyvinyl alcohol (PVA), decorative powder coating, nylon 12, ethylene vinyl acetate copolymer (EVA), PPT, PET, TPU, ABS, functional anti-corrosion powder coating, linear low-density polyethylene (LLDPE), etc.

Engineering plastics: General engineering plastics (PA, PA6, PA66, PA11, PA12, PC, POM, PBT, PET, PPO, PMMA), etc; Special engineering plastics (PPS, PI, PSF, PEEK, PCTFE, LCP, PTFE, PES, PAI, PAR), etc;

Modified plastics: General plastic engineering modified products (modified ABS, PP, PVC, PC); Modified engineering plastics (PPO, PA, POM, PC, PBT (PET), PSU); Modified special engineering plastics (PPS, PEEK, PEI, PSF, LCP);

Plastic and rubber raw materials, masterbatch: such as white masterbatch, other color masterbatch, etc; Ultra fine grinding of functional masterbatch, coloring and extraction masterbatch, pigment dyes, thermoplastic elastomers, engineering plastics, and other products.
3. In 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.

Food additives and condiments: pepper, black pepper, white pepper, green pepper, cinnamon powder, cumin powder, grass nut powder, Dahongpao pepper powder, cinnamon powder, red nut powder, red koji Rice noodles, cardamom powder, red pepper powder, garlic powder, star anise powder, clove powder, amomum powder, vanilla powder, cardamom powder, strawberry powder, yellow ginger powder, good ginger powder, five spice powder, fresh ginger powder, curry powder, sand ginger powder, onion powder, onion powder, mustard powder, meat nut powder, angelica powder, mountain angelica powder The pulverization of Nai powder, onion powder, cumin powder, spice powder, five spice powder, bulk powder and other food industry materials.

4. Biotechnology industry:

(1) Crushing active cells: Currently, we know that cell cryopreservation technology can ensure the viability of cells, and it is also advisable to use freezing technology to crush drugs. Low temperature cryogenic pulverization first involves low-temperature freezing treatment of drugs, using liquid nitrogen freezing method to freeze the drugs we need to pulverize. The drugs are directly cooled to the dormant state of cells and then pulverized by a pulverizer, but it is necessary to avoid local high temperatures that may awaken active cells during the pulverization process.
(2) Crushing spores and saponins: Plants with saponins can also undergo molecular recombination during the room temperature crushing process. Local high-temperature ginsenosides will degrade into other substances, and fungal spores using room temperature wall breaking methods will also damage the original components of the spores.
(3) Proteins and vitamins: In various animals and plants, specific protein and vitamin elements exist at room temperature or low temperature. We usually use ordinary crushing methods, but the crushing process can cause the things we need to be destroyed. By using low-temperature cryogenic technology for crushing, it is possible to ensure that the original element content is not lost.
4. Plastic recycling field:
Low temperature crushing method for low melting point plastics, high self-lubricating materials, waste rubber, and raw rubber. Applied to polymer materials such as polypropylene, polyethylene, polycarbonate, polyamide, polytetrafluoroethylene ABS、 Crush elastomers, raw rubber, rubber, phenolic compounds, polyesters, etc. to 10-700 mesh.
5. Substances with high moisture content:

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. The use of sheep placenta extract oral capsules is a major breakthrough.
6. Antioxidant pulverization:

Zinc, tin, aluminum and other metal micro powder technology.
7. Chemical industry: Potassium permanganate low-temperature ultrafine grinding technology.
