Low temperature mill main application This machine is suitable for pharmacy, food and chemical industry. Many naturally tough, sticky, fat-rich, or thermal-sensitive materials, or some of which have these properties as a result of the heat generated during the crushing process, cannot be pulverized into very fine powders even at high speeds. This is particularly advantageous for cold grinding, which, with the help of liquid nitrogen, pulverizes the above materials into fine powder. Liquid nitrogen embrittlement of the material and then crushing, the result is plastic and rubber particles can be pulverized into fine powder with good fluidity. Typical materials are: polynitride - elastic rubber - rubber and so on. In the feed industry, cold grinding is mainly used for processing materials, but in practice, other materials with low melting point, such as grease mixture, fermentation, heat-sensitive raw materials, etc., can also be used for cryogenic crushing of this equipment.
Working principle of ultra-low temperature pulverizer The cryogenic pulverizer system with liquid nitrogen as the cold source, crushed material through cooling at low temperature embrittlement is easy to crush after state, into the mechanical crusher cavity in the body by high-speed rotating impeller, the material and blade, tooth plate, repeated shocks, between material and material impact, shear, friction and so on comprehensive, crushing effect: after crushed material sieve airflow classifier for classification and collection, the fineness requirement did not meet the material return bin crush, air conditioning most to return to the recycling bin.
The characteristics The cryogenic pulverizer system in the process of material crushing, the cold source to form a closed cycle system, make full use of the energy, save energy consumption: crush with cold source temperature can drop to minus 196 degrees Fahrenheit, according to the material embrittlement point temperature, the temperature in the process of crushing, regulation of choosing excellent grinding temperature, reduce the energy consumption: grinding fineness can reach 10-700 mesh, and even reach micron mu fineness: use liquid nitrogen as grinding medium, realize the cryogenic crushing, the material of explosion-proof, anti-oxidation and so on synthesis effect.
