Working Principle

The KT-CG01 operates on a principle that combines the deep cold of liquid nitrogen with the high-speed crushing capabilities of an ultra-micro grinding machine. Here’s how it works:

1. Cooling Phase: Materials are first cooled and chilled using liquid nitrogen, which can reduce the temperature to -196°C.
2. Crushing Phase: The chilled materials enter the mechanical grinding machine cavity where they are subjected to high-speed rotation via an impeller.
3. Impact and Collision: The materials undergo repeated impact, collision, shearing, and friction with blades, toothed discs, and other materials, leading to pulverization.
4. Classification and Collection: The pulverized material is classified by an airflow sieve classifier and collected. Materials that do not meet the fineness requirement are returned for further pulverization.
5. Closed-Circuit System: The system operates in a closed-circuit circulation, ensuring energy efficiency and reduced energy consumption.

This process not only ensures ultra-fine pulverization but also maintains the chemical and physical properties of the materials, making it ideal for heat-sensitive and brittle materials.

Product Advantage

The KT-CG01 Liquid Nitrogen Cryogenic Grinding Machine offers several advantages over traditional pulverization methods:

• Preservation of Material Integrity: By using liquid nitrogen, the machine prevents thermal degradation, ensuring that the original nature and state of the material are preserved.
• Ultra-Fine Grinding: Produces particles with a fineness ranging from 40-300 mesh, or even micron-level fineness, improving particle flow and dispersion.
• Efficiency and Speed: The high-speed crushing mechanism significantly reduces production times, increasing overall efficiency and output.
• Uniform Particle Distribution: Generates ultra-fine particles within narrow distribution ranges, offering more uniform and consistent results.
• Cost-Effective: Despite its advanced features, the KT-CG01 is designed to be cost-effective, making it accessible for various industries and applications.
• Versatility: Capable of handling a wide range of materials, from plastics and rubber to biological samples and traditional Chinese medicine, making it a versatile tool in multiple fields.

In summary, the KT-CG01 Liquid Nitrogen Cryogenic Grinding Machine is a powerful and versatile tool for the pulverization of plastic raw materials and heat-sensitive materials, offering superior results with minimal thermal degradation and high efficiency.
