DFJ series low-temperature crusher

Main purpose:

This cryogenic crusher system is used for various materials that cannot be crushed at room temperature, and is widely used in the chemical, petrochemical, mechanical, marine, automotive, electronics industries, clothing, coatings, printing, engineering plastics, rubber, shoe materials, polytetrafluoroethylene, thermoplastic materials, hot melt adhesives, nylon, polyester, polypropylene, polyethylene, thermoplastic elastomers TPU, TPEE, nylon PA11, PA1010, PA12, PA6, PA66, PA610 copolymer nylon, EVA、PC、PS、 Ultra fine powder for food industry (black pepper powder), Chinese and Western medicinal materials, biotechnology and other products.

Working Principle:

The cryogenic crusher system uses liquid nitrogen as the cold source. After the crushed material is cooled at low temperature to achieve a brittle and easily crushed state, it enters the mechanical crusher chamber and rotates at high speed through the impeller. Under the comprehensive effects of repeated impacts, collisions, shearing, friction, etc. between the material and the blades, teeth, and materials, the crushing effect is achieved; The crushed material is classified and collected by an air flow sieve classifier; Materials that do not meet the fineness requirements are returned to the silo for further crushing, while most of the cold air is returned to the silo for recycling.

characteristic:

The complete set of cryogenic pulverizer for this product consists of a silo, mechanical pulverizer, induced draft fan, cyclone, vibrating screen, liquid nitrogen tank (user provided), etc. The cryogenic crusher system forms a closed-loop circulation system with its cold source during the material crushing process, allowing energy to be fully utilized and saving energy consumption; The temperature of the cold source used for crushing can be reduced to negative 196 degrees. According to the brittle point temperature of the material, its temperature can be adjusted during the crushing process, and the optimal crushing temperature can be selected to reduce energy consumption; The crushing fineness can reach 10-700 mesh, and even reach micro level fineness; Using liquid nitrogen as the grinding medium to achieve comprehensive effects such as ultra-low temperature crushing, material explosion prevention, and oxidation prevention.
