Why Choose Our Cryogenic Grinders?
Cryogenic grinding is a revolutionary process that uses liquid nitrogen to cool materials to extremely low temperatures before pulverization. This method is particularly beneficial for heat-sensitive materials, as it prevents thermal degradation and preserves the material's properties. Our cryogenic grinders are designed to handle a wide range of applications, from pharmaceuticals and food processing to industrial materials like plastics and rubber.
Key Features and Benefits
-
Ultra-Fine Pulverization: Our cryogenic grinders can achieve particle sizes as fine as 10-700 mesh, ensuring a uniform and precise grind. This is crucial for applications requiring consistent particle distribution, such as in pharmaceuticals and food processing.
-
Material Integrity Preservation: By maintaining materials at ultra-low temperatures, our grinders prevent thermal degradation, oxidation, and loss of volatile compounds. This is especially important for heat-sensitive materials like spices, coffee, and certain pharmaceuticals.
-
Energy Efficiency: The closed-circuit circulation system in our grinders ensures that energy is fully utilized, reducing overall energy consumption. The ability to adjust the temperature based on the material's embrittlement point further enhances energy efficiency.
-
Versatility: Our grinders are capable of processing a wide variety of materials, including plastics, rubber, pharmaceuticals, and food grades. This makes them an invaluable tool for industries with diverse grinding needs.
-
Increased Productivity: The optimized particle size and increased throughput of our cryogenic grinders lead to higher production rates and lower grinding costs. The elimination of caking within the mill also contributes to smoother operations.
Applications of Cryogenic Grinding
-
Food Processing: Cryogenic grinding is ideal for processing heat-sensitive food items like cheese, dried fruits, and oily spices. It helps maintain flavor and nutritional value while achieving the desired particle size.
-
Pharmaceuticals: In the pharmaceutical industry, cryogenic grinding is used to pulverize active ingredients and excipients without compromising their efficacy. This is particularly important for drugs that are sensitive to heat or oxidation.
-
Industrial Materials: Cryogenic grinding is widely used in the manufacturing of plastics, rubbers, pigments, and coatings. It allows for the fine grinding of materials like carbon black without thermal degradation.
-
Recycling: Cryogenic grinding plays a crucial role in the recycling industry, where it is used to pulverize materials for reuse. This process is efficient and environmentally friendly, contributing to sustainable manufacturing practices.
How It Works
Our cryogenic grinders operate by feeding the material into a hopper, where it is then conveyed to a helical screw conveyor. Liquid nitrogen is sprayed into the conveyor to cool the material to the desired temperature. The material is then pulverized in a high-speed mechanical pulverizer, where it undergoes repeated impact, collision, shearing, and friction. The pulverized material is classified by an airflow sieve classifier, and any material that does not meet the fineness requirement is returned to the silo for further grinding.

FAQ
What Is A Cryogenic Grinder And How Does It Work?
A cryogenic grinder is a device that uses liquid nitrogen to cool and grind materials at very low temperatures. The material is first cooled to a brittle state using liquid nitrogen, then fed into a grinding chamber where it is pulverized by high-speed rotating blades or impellers. The process involves repeated impact, collision, shearing, and friction to achieve fine particle sizes. The ground material is then classified by an airflow sieve, and any material that does not meet the required fineness is returned to the grinding chamber for further processing.
What Are The Main Applications Of Cryogenic Grinders?
Cryogenic grinders are widely used in various industries, including food processing, manufacturing, steel grinding, and recycling. In food processing, they are used to grind heat-sensitive materials like cheese, dried fruits, and spices while preserving their flavor. In manufacturing, they are used to pulverize materials like carbon black without thermal degradation. In steel grinding, they help manage heat generated during the grinding process. In recycling, they play a crucial role in processing materials efficiently.
What Are The Advantages Of Using A Cryogenic Grinder?
Cryogenic grinders offer several advantages, including increased productivity through optimized particle size and higher throughput, elimination of caking within the mill, decreased wear on grinding equipment, and the ability to separate composite materials. They also provide a higher production rate, lower energy consumption, finer particle size, more uniform particle distribution, and lower grinding costs. Additionally, they improve pouring properties of materials and reduce microbial load.
Why Is Liquid Nitrogen Used In Cryogenic Grinding?
Liquid nitrogen is used in cryogenic grinding because it provides the necessary refrigeration to cool materials to very low temperatures (down to -196°C). This cooling makes the materials brittle, allowing them to be easily pulverized. Liquid nitrogen also absorbs the heat generated during the grinding process, preventing thermal degradation and maintaining the material's properties. It is an effective and safe cooling medium for achieving ultra-fine grinding results.
What Types Of Materials Can Be Processed Using A Cryogenic Grinder?
Cryogenic grinders can process a wide range of materials, including plastics, rubber, pharmaceuticals, food grades, plant and animal tissues, and heat-sensitive materials. They are particularly effective for materials that are susceptible to oxidation or contain volatile substances, such as carotene, vitamins, coffee, and spices. Cryogenic grinding is also suitable for materials that require fine particle sizes and uniform distribution.
How Does Cryogenic Grinding Improve Material Properties?
Cryogenic grinding improves material properties by reducing particle size to a fine and uniform level, which enhances the material's flowability and mixing characteristics. It also preserves the material's integrity by preventing thermal degradation and oxidation. Additionally, cryogenic grinding can reduce microbial load and improve the material's visual appearance by minimizing speckling. These improvements make the material more suitable for various applications, including pharmaceuticals, cosmetics, and food processing.
