Main purpose:
This liquid nitrogen pulverization unit can be widely used for material pulverization in industries such as pharmaceuticals, food, chemicals, and national defense research.
Especially for thermosensitive substances, traditional Chinese and Western medicine, animal and plant tissues, rubber, plastics, and 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 even greater effectiveness. All parts of this unit that come into contact with crushed materials are made of stainless steel material, which has good corrosion resistance. The frame is completely enclosed around it for easy cleaning, and the inner wall of the casing is processed to achieve a flat and smooth surface. Make the production of drugs, food, chemicals, etc. more in line with the "GPM" standards.

Technical Parameter
(1) Grinder workshop diameter Φ 450mm (4) Working medium: liquid nitrogen
(2) Crusher power: 45KW (5) Operating temperature: 0 ° C to -196 ° C (adjustable)
(3) Feeding motor: 1.5KW (6) Grinding fineness: 100-300 mesh

The unit mainly consists of a pre cooling bin, a feeding screw, a main engine, a feeding fan, a cyclone separator, pipelines, an electrical control cabinet, a liquid nitrogen tank, and liquid nitrogen connecting hoses.
This equipment is suitable for the crushing process of various materials and working conditions. The temperature of the crushing chamber can be adjusted according to the different catalytic points of different materials. During the crushing process, the temperature can be controlled by selecting the crushing temperature to reduce energy consumption. The crushing fineness can reach 10-300 mesh, and even finer fineness. Liquid nitrogen is used as the grinding medium to achieve comprehensive effects such as ultra-low temperature crushing, material explosion prevention, and explosion prevention. The crushed finished product has the characteristics of no deterioration, no oxidation, and good geometric shape.
