Liquid Nitrogen Cooling Plastic Pulverizer

Liquid nitrogen Cooling Plastic Pulverizer, also known as freezer milling, freezer grinding, and Freezing Pulverizer is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens. When chilled by dry ice, liquid carbon dioxide or liquid nitrogen, the thermoplastics can be finely ground to powders suitable for electrostatic spraying and other powder processes. Samples that require extraction of nucleic acids must be kept at −80 °C or lower during the entire extraction process. For samples that are soft or flexible at room temperature, cryogenic grinding may be the only viable technique for processing samples.

Description:
Liquid nitrogen Cooling Plastic Pulverizer, also known as freezer milling, freezer grinding, and Freezing Pulverizer is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens. When chilled by dry ice, liquid carbon dioxide or liquid nitrogen, the thermoplastics can be finely ground to powders suitable for electrostatic spraying and other powder processes. Samples that require extraction of nucleic acids must be kept at −80 °C or lower during the entire extraction process. For samples that are soft or flexible at room temperature, cryogenic grinding may be the only viable technique for processing samples.

Working Principle:
This Cryogenic Pulverizer using liquid nitrogen to lower the input material temperature to material embrittlement condition firstly, then go to the grinding chamber, the input materials were thoroughly pulverized through blade wheel’s high speed rotating, and the comprehensive force like mutual repeatedly impact, crash, shear and friction between the materials and blades, fluted disc, materials and materials.
Grinded materials will be classified and collected by air screen cone type classifier, the grinded material or powder which have not reached the material fineness degree which go back the grinding chamber for re-grinding, most of the cool air will return back to grinding chamber for recycling usage.

Features:
While grinding, the cooling source is forming a closed-circuit circulation system, The cryogenic pulverizer system, so the cooling source will be thoroughly used, save energy; and the particle fineness degree rang from 10-700 mesh, even reach micron fineness degree. Apply liquid nitrogen as grinding medium, achieve cryogenic grinding, anti-explosion, anti-oxidation, etc effect.

Applications:
This cryogenic pulverizer system can be used for all kinds of materials which can not be crushed/grinded in normal temperature, widely apply for all kinds of oily/sugary foodstuff, chemical, petroleum, machinery, ship, costume, coating, printing, resin, engineering plastic, rubber, shoe material, thermoplastic material,thermosol, nylon, polyester, PP, PE, thermoplastic-elastomer TPU/TPEE, Nylon material PA11、PA1010、PA12、PA6、PA66、PA610 copolymer nylon, PET, PTFE, PE, EVA, food industry (chilli powder), Chinese and Western Medicinal materials’super fineness grinding.

Configuration:
Liquid nitrogen tank→material solo → machinery grinding machine → draught fan → powder discharging cyclone
