The structural characteristics of low-temperature cryogenic crushers can be summarized as follows:
1、 Core cooling system
1. Liquid nitrogen cycle refrigeration
Using liquid nitrogen as the cold source, the material is cooled to below the embrittlement point (with a minimum of -196 ℃) through a closed-loop circulation system, achieving low-temperature embrittlement of the material.
2. Temperature control module
Equipped with precision temperature control device, the cooling temperature can be adjusted according to the characteristics of the material, optimizing the crushing efficiency.
3. Efficient cold energy recovery
Most of the air conditioning is reused through closed-loop circulation, significantly reducing energy consumption.
2、 Design of crushing mechanism
1. Composite crushing chamber
Vertical structure design, equipped with high-speed rotating impellers, toothed discs, and cutting tools, capable of crushing materials through multiple effects such as impact, shear, and friction.
Combining mechanical and airflow crushing technology, the special blade structure expands the crushing range.
2. Grading and Collection System
Configure an airflow screening classifier to automatically separate particles of different fineness, and return materials that do not meet the standards to the crushing chamber for recycling processing.
3、 Function and performance optimization
1. Ultra fine crushing ability
It can handle fineness of 10-700 mesh or even micrometer level, and hard and brittle materials can reach 12-44 μ m (D98).
2. Anti oxidation and explosion-proof design
Low temperature environment inhibits material oxidation, and liquid nitrogen medium reduces the risk of dust explosion.
4、 Special application adaptation structure
1. Compact laboratory model
Small devices are lightweight and can be placed on laboratory countertops for easy operation.
2. Low temperature resistant material components
Key components such as evaporators are made of titanium tubes or 316L stainless steel materials, suitable for ultra-low temperature environments.
In summary, the low-temperature cryogenic crusher is designed with closed-loop refrigeration, composite crushing chamber, grading system, and material optimization to achieve efficient crushing, energy conservation, environmental protection, and safety. It is suitable for the ultrafine processing needs of high toughness and heat sensitive materials.
