Liquid Nitrogen Crusher Cryogenic Pulverizer 10-1000 Mesh Powder Grinding Machine

Liquid Nitrogen Crusher Cryogenic Pulverizer Grinder Powder Grinding Machine
 
Cryogenic Pulverizer
 

1. Working principle and characteristics

The whole set of freezing pulverizer of this product is composed of silo, mechanical pulverizer, induced draft fan, cyclone, vibrating screen, liquid nitrogen tank, etc.

Working principle
The cryogenic pulverizer system uses liquid nitrogen as the cold source. After the pulverized material is cooled at a low temperature to achieve embrittlement and easy pulverization, it enters the cavity of the mechanical pulverizer and rotates at high speed through the impeller. The material and the blade, the toothed disc, the material and the material Under the combined effect of repeated impact, collision, shearing, friction, etc., the crushing effect is achieved: the crushed materials are classified and collected by the air sieve classifier; the materials that do not meet the fineness requirements are returned to the silo to continue crushing. Most of the cold air is returned to the silo for recycling.

Features
In the process of material crushing, the cold source of the refrigerated pulverizer system forms a closed-circuit circulation system, so that the energy can be fully utilized and energy consumption is saved: the temperature of the cold source used for crushing can be reduced to minus 196 degrees, according to the brittle point temperature of the material. , in the crushing process, its temperature can be adjusted, and the optimal crushing temperature can be selected to reduce energy consumption: the crushing fineness can reach 40-200 mesh to micron μ and other fineness: using liquid nitrogen as the grinding medium to achieve ultra-low temperature crushing, the material The comprehensive effect of explosion-proof and anti-oxidation.

2. Scope of use

The refrigerated pulverizer system is used for various materials that cannot be pulverized at room temperature, and is widely used in various chemical, petrochemical, machinery, shipbuilding, automotive, electronic Hot melt adhesive, nylon, polyester, polypropylene, polyethylene, food industry (chili powder), Chinese and Western medicinal materials, nylon, polyester, hot melt adhesive, various engineering plastics, polyethylene, polyvinyl alcohol, polystyrene (PS), thermoplastic elastomers, TPU, general plastics, high density polyethylene (HDPE), polypropylene, thermal adhesives, PA1010, low density polyethylene (LDPE), hot melt adhesives for clothing, decorative powder coatings, nylon 66, Medicine, nylon 11, ethylene acetate copolymer (EVA), nylon 6, nylon 12, plastic, rubber, PPT, PET, TPU, ABS, functional anti-corrosion powder coating, linear low density polyethylene (LLDPE), etc. Engineering plastics: general engineering plastics (PA, PA6, PA66, PA11, PA12, PC, POM, PBT, PET, PPO, PMMA), etc.; special engineering plastics (PPS, PI, PSF, PEEK, PCTFE, LCP, PTFE, PES) , PAI, PAR), etc.; 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 rubber raw materials, various masterbatches and color masterbatches: such as white masterbatch, other color masterbatches, etc.; functional masterbatch, coloring masterbatch Ultrafine grinding of granules, pigment dyes, thermoplastic elastomers, engineering plastics, etc. The technology can be widely used in chili powder, pepper powder, black pepper powder, white pepper powder, green hemp pepper powder, cinnamon powder, cumin powder, grass powder, Dahongpao pepper powder, cinnamon powder, Hongkou powder, red yeast rice noodles , cardamom powder, red sesame pepper powder, garlic powder, star anise powder, clove powder, amomum powder, geranium powder, cardamom powder, grass fruit powder, turmeric powder, galangal powder, five-spice powder, fresh ginger powder, curry powder, Sand ginger powder, chive powder, onion powder, mustard powder, meat powder, angelica powder, green onion powder, cumin powder, spice powder, five-spice powder, aniseed powder and other food industry materials crushing.
