Plastic low-temperature freeze crusher

Plastic low-temperature freeze crusher is mainly used to crush various materials that cannot be crushed at room temperature, and is widely used in the field of chemical coatings:

Metal wall coating fieldPowder for PTFE, PA, PC, PU, PP, PE coatings; Adhesive coating, high bonding coating;
Silent coating: elastomer, nano sound-absorbing coating;
Anti corrosion coating; The raw materials used for absorbing coatings are finely ground. Low density polyethylene (LDPE), clothing hot melt adhesive, polyvinyl alcohol (PVA), decorative powder coating, nylon 11, ethylene vinyl acetate copolymer (EVA), PPT, PET, TPU, ABS, functional anti-corrosion powder coating, linear low-density polyethylene (LLDPE), etc.
engineering plasticGeneral 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 and rubber raw materials, various masterbatch and color masterbatchSuch as white masterbatch, other color masterbatch, etc; Ultra fine grinding of functional masterbatch, coloring and extraction masterbatch, pigment dyes, thermoplastic elastomers, engineering plastics, and other products.

The composition structure and process flow of cryogenic crusher

The complete set of low-temperature grinding machine for this product consists of a silo, mechanical crusher, induced draft fan, cyclone, airflow screen (customized by the user), vacuum automatic feeding (customized by the user), liquid nitrogen tank (customized by the user), etc.

Cryogenic crusher - Low temperature crusher: This equipment uses liquid nitrogen as a refrigerant to lower the material being crushed to the glass transition temperature, utilizing the property of the material becoming brittle at low temperatures. Crush materials under high-speed impact and friction. The crushed product has the characteristics of no deterioration, no oxidation, uniform particle size distribution, and good geometric shape. This technology is widely used in the food industry, pharmaceutical industry, plastic industry, chemical industry, scientific research, aerospace and other fields.

Working principle of cryogenic crusher

The low-temperature grinding machine system uses liquid nitrogen as the cold source. After the crushed material is cooled to achieve a brittle crushing state at low temperature, it enters the mechanical crushing 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 materials are classified and collected by an air flow screening machine. Materials that do not meet the fineness requirements are returned to the material bin for further crushing, while most of the cold air is returned to the material bin for recycling.

Working characteristics of cryogenic crusher

The low-temperature grinding machine system forms a closed-loop circulation system with its cold source during the material crushing process, which fully utilizes energy and saves energy consumption; The temperature of the cold source used for crushing can be reduced to -196 degrees Celsius. 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 fineness of crushing can reach 10-700 mesh, and even reach micron 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.
