Product Details

Laboratory type low-temperature cryogenic crusher

This low-temperature freeze crusher can be widely used for material crushing in industries such as pharmaceuticals, food, chemicals, and national defense research. Specially suitable for thermosensitive substances, traditional Chinese and Western medicine, animal and plant tissues, rubber, plastics, and other materials that exhibit toughness at room temperature and cannot be crushed. Low temperature crushing is the process of first freezing the above-mentioned substances to a brittle point. Then it is crushed to the required fineness in the crusher, and the original components will not be destroyed. And substances that are flammable and explosive at room temperature can also be crushed at low temperatures, resulting in more significant effects.

Working principle of cryogenic crusher

By using a cold source to exchange heat with the material; Reduce the temperature of the material to a brittle state; The brittle material undergoes countless impacts, shearing, and friction through the grinding mechanism in the grinding chamber, and finally becomes fine particles. The fineness of the ground material can reach the micrometer level. According to the performance of the material, a cooling strategy can be selected, using liquid nitrogen as the refrigerant with the lowest cooling temperature, which makes its cooling speed very fast. It is the preferred coolant for certain materials that require rapid cooling and low brittleness temperature. Materials that do not require high cooling embrittlement temperature can undergo heat exchange with a cold source.

Working characteristics of cryogenic crusher

The unit is mainly composed of a pre cooling compartment Feeding screw, host, feeding fan, cyclone separator, pipeline, electrical control cabinet Liquid nitrogen tank, liquid nitrogen connecting hose Composed of equal parts.

(1) This equipment is suitable for various materials and working conditions in the crushing process. The temperature of the crushing chamber can be adjusted according to the different catalytic points of different materials. During the crushing process, energy consumption can be reduced by adjusting the crushing temperature.
(2) The fineness of crushing can reach 10-300 mesh, and even finer fineness.
(3) Using liquid nitrogen as the grinding medium to achieve comprehensive effects such as ultra-low temperature crushing, material explosion prevention, and oxidation prevention.
(4) The crushed finished product has the characteristics of no deterioration, no oxidation, and good geometric shape.
