Applications:
This cryogenic pulverizer system can be used for all kinds of materials which can not be crashed/grinded in normal temperature, widely apply for all kinds of oily food containing sugar, chemical, petrochemical, machinery, shipbuliding, and auto-industry, 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 products's super fineness grinding.

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

Working Principle:
This PNCP series 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 throughly 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 will 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 of cryogenic pulverizer system is forming a closed -circuit circulation 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. In the pulverizing system, the cold source forms a closed cycle system, which makes full use of energy and saves energy. The temperature of the cold source for grinding can be reduced to 196 degrees below zero. According to the brittle point temperature of the material, the temperature can be controlled in the grinding process, and the best grinding temperature can be selected, so as to reduce the energy consumption. The grinding fineness can reach 10-700 meshes, and even reach micron fineness. In addition, liquid nitrogen is used as grinding medium to achieve ultra-low temperature comminution, which can achieve the comprehensive effect of explosion proof and oxidation resistance of materials.
