MCPT Series Cryogenic Grinder Machine MCPT Series Cryogenic Grinder Machine

MCPT series cryogenic mills use liquid nitrogen to cool the material before and during the grinding process. The extremely low temperature prevents the melting of low melting point materials and produces finer particles. It can be used to grind polymers such as engineering resins, rubber and adhesives, and pharmaceuticals, including food-grade materials into high-quality powders. This series has laboratory cryogenic mills suitable for R & D sampling and testing, as well as large-scale cryogenic grinder suitable for mass production.

Product Profile

The full set of deep cryogenic grinder is composed of feeding bin, mechanical pulverizer, induced draft fan, cyclone, vibration sieve, liquid nitrogen tank.
In the process of pulverizing, the cold source comes into being a closed loop system, which makes full use of energy and save the engery. The cold medium temperature can be reached upto -196 degree Celsius. It can be adjusted according to the brittleness point of different stuffs. The pulverizing powder granule ranges from 50-400 mesh. Using liquid nitrogen as medium achieves ultra-low temperature pulverizing to avoid the explosion and oxidation and so on.

The low temperature grinding machine system used for various materials which can't be shattered in room temperature, and is widely used in all kinds of chemical, petrochemical, machinery, ship, automobile industry, electronic industry, clothing, coatings, printing, engineering plastic, rubber, shoes, thermoplastic materials, hot melt adhesive, nylon, polyester, polypropylene and polyethylene, thermoplastic elastomer TPU, TPEE, nylon PA11, of PA1010, PA12, PA6, PA66, PA610 copolymerization of nylon, polyester, Polytetrafluoroethylene, EVA, food industry (chili powder), Chinese and western medicine and so on the products.

Working principle
This deep cold pulverizer system takes liquid nitrogen as cold source and use the brittleness of the stuffs under cold temperature. When the cold brittle stuffs enter into the pulverizer chamber, with high speed revolution of impellers, the stuffs inside will be pulverized through the integrated effects of mutual repeat impact, collision, shearing, rubbing between stuffs and stuffs, stuffs and vane, stuffs and gear plate. The stuffs after pulverization will be classified and collected. The particles which haven’t reached the size requirement will be returned back to the bin and pulverized again, most of the cooling air will be also recycled.
