Detail & Parts

Product Feature

The Liquid Nitrogen Cryogenic Grinding Machine Airflow Ultrafine Pulverizer boasts several unique features that set it apart from traditional pulverizers:

• High Fineness: The machine can achieve pulverization fineness ranging from 40-300 mesh for low-temperature crushing and up to 300 mesh-1000 mesh for brittle materials at room temperature. This high fineness ensures that the materials retain their original properties and are suitable for detailed analysis and research.
• Small Size and Light Weight: Designed with a compact and lightweight structure, this pulverizer can be conveniently placed on laboratory countertops, making it highly accessible for users.
• Cryogenic Pulverization: Utilizing liquid nitrogen as a cooling medium, the machine can achieve ultra-low temperature pulverization, which is particularly beneficial for heat-sensitive and tough materials. This process ensures that the materials do not degrade or change their properties during pulverization.
• Safety and Ease of Use: The machine features a fully enclosed structure, reducing the risk of operator exposure to the pulverizing chamber. Additionally, its continuous feeding type design allows for easy operation with minimal supervision.
• Efficient Material Collection: The cyclone type material collection method ensures efficient and clean material collection, reducing waste and improving overall efficiency.

Working Principle

The Liquid Nitrogen Cryogenic Grinding Machine Airflow Ultrafine Pulverizer operates on a sophisticated principle that combines high-speed impact and airflow vortex pulverization. Here’s a detailed breakdown of its working mechanism:

1. Liquid Nitrogen Cooling: The material to be pulverized is first cooled using liquid nitrogen, which reduces its temperature to as low as -196°C. This cooling process embrittles the material, making it easier to pulverize without causing thermal degradation.
2. High-Speed Rotation: The cooled material enters the pulverizing chamber where it is subjected to high-speed rotation of blades (up to 25,000 r/min). The high-speed rotation creates a vortex of airflow that further aids in the pulverization process.
3. Impact and Shearing: The material is subjected to repeated impact, collision, shearing, and friction between the blades, toothed disc, and other materials within the chamber. This multi-faceted action ensures thorough and efficient pulverization.
4. Airflow Classification: The pulverized material is then classified by an airflow sieve classifier. Materials that meet the required fineness are collected, while those that do not are returned to the chamber for further pulverization.
5. Closed-Circuit Circulation: The system operates in a closed-circuit circulation, ensuring that energy is fully utilized and energy consumption is minimized. This also helps in maintaining a consistent environment within the chamber, further enhancing the pulverization process.

Product Advantage

The Liquid Nitrogen Cryogenic Grinding Machine Airflow Ultrafine Pulverizer offers several advantages that make it a superior choice for laboratory and industrial applications:

• Increased Productivity: The optimized particle size and increased throughput ensure higher production rates, reducing overall production times and maximizing output.
• Elimination of Caking: The use of liquid nitrogen prevents the formation of caked product within the mill, ensuring a continuous and smooth pulverization process.
• Decreased Wear on Equipment: The ultra-low temperature pulverization reduces wear on grinding equipment, extending its operational life and reducing maintenance costs.
• Separation of Composite Materials: The machine is capable of separating composite materials within the mill, ensuring that each component is pulverized to the required fineness.
• Lower Energy Consumption: The closed-circuit circulation system and the use of liquid nitrogen as a grinding medium result in lower energy consumption, making the machine more cost-effective.
• Fine Particle Size: The machine can achieve pulverization fineness ranging from 10-700 mesh, or even micron-level fineness, ensuring that the materials are finely ground and suitable for detailed analysis.
• Uniform Particle Distribution: The cryogenic milling process generates ultra-fine particles within narrow distribution ranges, ensuring uniformity and consistency in the final product.
• Improved Pouring Properties: The finely ground materials improve the pouring properties, making them easier to handle and process in downstream applications.
• Reduction in Microbial Load: The low-temperature pulverization process also helps in reducing the microbial load, making the machine suitable for applications requiring sterile conditions.

In summary, the Liquid Nitrogen Cryogenic Grinding Machine Airflow Ultrafine Pulverizer is a versatile and efficient tool for the fine grinding of a wide range of materials. Its unique features and advantages make it an indispensable asset for laboratories and industries requiring precise and consistent pulverization.
