Ultra-cold shredder

- Jul 26, 2019-

With liquid nitrogen for the super cold mill system as the cold source, material is crushed through cooling at low temperature embrittlement is easy to shatter, into the mechanical crusher cavity in the body by high-speed rotating impeller, the material and blade, tooth plate, the interaction between the material and the material repeated shocks, collision and 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 whole set of cryogenic crusher is composed of silo, mechanical crusher, induced draft fan, cyclone, vibrating screen, liquid nitrogen tank, etc.

The characteristics 

The super cold mill 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 the best 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.

Using range

The super cold mill system used in room temperature can't crush all kinds of material, widely used in all kinds of chemical, petrochemical, machinery, shipbuilding, automobile industry, electronic industry, clothing, coating, printing, engineering plastics, rubber, thermoplastic materials, hot melt adhesive, nylon, polyester, polypropylene, polyethylene, the food industry (paprika), Chinese and western medicine, nylon, polyester, hot melt adhesive, all kinds of engineering plastics, polyethylene, polyvinyl alcohol, polystyrene (PS) and thermoplastic elastomer, TPU, General plastic, high density polyethylene (HDPE), polypropylene, thermal plastic, PA1010, low density polyethylene (LDPE), clothing, decorative coating, hot-melt adhesive nylon 66, medicine, nylon 11, vinyl acetate copolymer (EVA), nylon 6, nylon 12, plastic, rubber, PPT, PET, TPU, ABS, functional anticorrosion coating, linear low density polyethylene (LLDPE) etc. Engineering plastics: general engineering plastics (PA, PA6, PA66, PA11, PA12, PC, POM, PBT, PET, PPO, PMMA); Special engineering plastics (PPS, PI, PSF, PEEK, PCTFE, LCP, PTFE, PES, PAI, PAR); Modified plastics: general plastic engineering modified products (modified ABS, PP, PVC, PC); Modified engineering plastics (PPO, PA, POM, PC, PBT (PET), PSU); Modified special engineering plastics (PPS, PEEK, PEI, PSF, LCP); Plastic and rubber raw materials, various master batch and color master batch: such as white master batch, other color master batch, etc. Super fine crushing of functional masterbatch, colored extraction masterbatch, pigment dyes, thermoplastic elastomers, engineering plastics and other products. The technology can be widely used in chili powder, pepper, black pepper, white pepper, green pepper powder, cinnamon, cumin powder, bandits, dahongpao, Chinese prickly ash powder, cinnamon, red kous, red kojic rice, nutmeg, kenaf pepper powder, garlic powder, star anise, clove, amomum villosum, bay leaf, nutmeg, good grass fruit powder, turmeric powder, ginger powder, spices, fresh ginger powder, curry powder, ginger powder, shallot powder, onion powder, mustard powder, meat powder, angelica dahurica powder, Kew resurrectionlily powder, green Chinese onion powder, fennel powder, spices powder wait, five-spice powder, aniseed powder and so on food industry material crushing.
