The ultra-low temperature crusher consists of a pre cooling material bin, mechanical crusher, induced draft fan, primary cyclone separator, fully automatic feeder, liquid nitrogen tank, and control cabinet.

working principle:

1. The refrigerant exchanges heat with the material to make it brittle. The brittle material undergoes countless impacts, shearing, and friction through the crushing structure in the crushing chamber, forming fine particles. The fineness of the crushed material can reach the micrometer level.

2. Refrigerants can be selected based on the differences in material properties and characteristics. If liquid nitrogen is used as the refrigerant, its low cooling temperature can reach minus 196 degrees Celsius, and the cooling speed is very fast

For certain materials that require rapid cooling and low brittleness temperature, liquid nitrogen is the preferred refrigerant. For some materials that do not require high brittleness temperature, compressed air or pre cooled air from an air conditioner can be used for heat exchange with the material.

Main purpose:

1. Chemical and coating fields:

① Metal wall coating field: powders for PTFE, PA, PC, PU, PP, PE coatings.

② Plastic coatings: adhesive coatings, high bonding coatings, soundproof coatings: elastomers, nano sound-absorbing coatings.

③ Anti corrosion coating, absorbing coating, etc.

④ In the process of primary color grinding (natural color masterbatch grinding). Every year, multiple machines, contracts, and other transaction documents are exported to Europe, America, and other countries for future reference.

2. Food and health care products: the crushing and extraction of animal and plant fruits, traditional Chinese patent medicines and simple preparations, natural and synthetic elements can ensure that the original elements will not be lost in the crushing process.

3. Recycling field: low-temperature crushing of low melting point materials, high self-lubricating materials, waste rubber, raw rubber, etc.

4. This series of machines belongs to micro powder technology and is used for polymer materials such as: ① polypropylene, polyethylene, polycarbonate, polyamide, polytetrafluoroethylene ABS、 Extracts such as elastomers, rubber, raw rubber, synthetic fibers, seaweed, etc. ② Grinding of special materials such as strong fibrous materials, animal placenta extract, honeycomb, and body fluids. ③ The application of polyester powder coatings is widely used, and the use of sheep placenta oral capsules is a major breakthrough. ③ Anti corrosion coating, absorbing coating, etc.
