Product Applications:
This product is widely applicable for material crushing in industries such as food, chemicals, and scientific research, particularly for thermosensitive materials, rubber, plastics, Chinese and Western medicine.
Materials such as plants, animals, and substances that are resilient at room temperature and cannot be crushed. Examples include extracts, gums, fats, etc. Low-temperature crushing involves first freezing the aforementioned materials below their脆ification point, and then crushing them to the desired fineness within a crusher.
The original components will not be damaged. Moreover, materials that are flammable and explosive at room temperature can also be finely crushed at low temperatures, with even more pronounced effects.
Working Principle:
This product consists of a material pre-cooling storage, a screw propeller, a low-temperature granulator, a low-temperature blower, a cyclone separator, a dust filter, and an electrical control cabinet. Material enters the pre-cooling storage.
After being cryogenically frozen with liquid nitrogen to below the脆ification point, the material is then spirally pushed into the cavity of the low-temperature grinder. Under the interaction of high-speed rotating blades and fixed gears, the material impacts and rubs within the cavity, achieving the desired pulverization effect.
Fineness of the powder can be controlled by adjusting the speed of the moving blades and the fan. The faster the speed of the moving blade disk, the finer the fineness; the faster the fan speed, the coarser the material. The finely ground powder in the cyclone separator is subjected to the rotational centrifugal force of the separator.
Under the action of the induced draft fan, dust automatically flows to the outlet. Dust enters the pulse dust collector, is filtered, and then recycled for reuse. Most of the cold air returns to the storage bin for recirculation.
Product Features:
The refrigerated crushing system utilizes a closed-loop circuit for its cold source during the material crushing process, ensuring the full utilization of energy and energy savings.
2. The cold source for crushing can be reduced to -196 degrees Celsius. The temperature during the crushing process can be adjusted according to the material's脆化点 temperature, selecting the optimal crushing temperature to reduce energy consumption.
3. Fineness can reach 10-700 mesh, even to the micron (μ) level.
4. Utilizing liquid nitrogen as the grinding medium, achieving ultra-low temperature crushing, as well as comprehensive effects such as explosion prevention and oxidation resistance for the material.
