The liquid nitrogen crusher can be widely used for material crushing in pharmaceutical, food, chemical industry, national defense , scientific research and other industries.
For heat sensitive substances, Chinese and Western medicine, tissues of animals and plants, rubber, plastic and other materials which are tough and can not be crushed at room temperature.
The cold milling machine is a cryogenic grinder of derivative products, compared to the small size, low loss, low energy consumption, simple operation, is China's first set of productivity and energy efficiency in one of the mill. Widely used in the food industry, the pharmaceutical industry and test polymer materials and the like.
The cryogenic mill system in material crushing process, the cold source to form a closed-loop system that allows full use of energy, save energy; crushed with a cold source temperature can be reduced to -196 degrees, according to the material brittle point temperature, the temperature in the grinding process can be adjusted to select the best ground temperature and reduce energy consumption. Grinding fineness can reach 10-700 mesh, even to the fineness of micron and so on. Use liquid as the grinding media, to achieve ultra-low temperature grinding, explosion-proof materials, oxidation and other comprehensive results.
Cryogenic comminution is that the materials which are metioned above are frozen to a brittle temperature, then it is crushed into the required fineness in the crusher, and the original composition will not be destroyed. In addition, flammable and explosive materials at room temperature can also be crushed at low temperature by this machinery which is of high efficiency.
The liquid nitrogen cryogenic mill systems for the cold source, after being crushed material crushed by cooling to achieve brittle state at a low temperature, into the cavity through the high-speed rotating machinery grinder impeller, materials and blades, tooth plate, materials and materials of repeated impact between each other, under the impact, shear and friction, combined effects, to the crushing effect; the material is crushed airflow screening machine grading and collected does not reach the required fineness of the material to return silos continue crushing, large air-conditioning partial returns recycling bin.
