Cryogentic mill

Operation process and application scenarios

During operation, the machine will be injected with liquid nitrogen at -196℃ to enable cryogenic grinding.When a substance drops below a certain temperature, it rapidly becomes brittle—a property known as cryogenic brittleness. Leveraging this trait, battery additives that are hard to grind at room temperature (such as phosphorus pentasulfide (P₂S₅), CMC, asphalt, resins, gums, and raw materials with high oil or moisture content) can be easily pulverized. The cryogenic grinding method is widely used across various industries and has made remarkable contributions to industrial development.

Crushing principle

①   Ultra-low temperature liquid nitrogen is injected during raw material feeding, and the raw material freezes to develop cryogenic brittleness.

② The frozen raw material is fed into the cryogenic grinder.

③ Grinding rotors A and B rotate at high speed in clockwise and counterclockwise directions, doubling the peripheral speed.

④ Shearing force from pin impact instantly micronizes the raw material, which is discharged immediately

Frozen Pulverization System

To meet diverse modern needs—especially for materials hard to grind at room temperature—we’ve developed a dedicated cryogenic grinder using liquid nitrogen. As the latest addition to our product lineup, this cryogenic grinder delivers a high-spec cryogenic grinding system for your company

Centered on the rotating base, its structure has been fully optimized for cryogenic grinding, ensuring stable operation even under harsh ultra-low temperature conditions. Thus, thermoplastic resins, oil-containing foods, and other materials previously difficult to grind at room temperature or even -10℃ can now be crushed stably via the cryogenic brittleness principle enabled by liquid nitrogen.

Beyond the grinder itself, we also offer complete turnkey solutions, including dedicated feeding equipment and cyclone separators, covering end-to-end manufacturing and configuration.

Detailed application field

Application Fields

All-solid battery solid electrolyte,CMC, asphalt, resin, gum, pigment, chemicals, food, health food, beverage, traditional Chinese medicine

Features

Excellent Fluidity

The ground particles become smooth, enhancing the product’s fluidity.

No Thermal Degradation

It can inhibit quality deterioration caused by grinding heat, which is prone to occur under normal temperature conditions.

Non-Oxidation

Both cryogenic treatment and grinding are performed in a nitrogen-filled environment, inhibiting the oxidation reaction of substances during the grinding process.
