Low temperature pulverizer

Cm-420 type super cold pulverizer (deep cold pulverizer) 1 Working principle and characteristics the whole set of super cold pulverizer is composed of silo, mechanical pulverizer, induced draft fan, cyclone, vibrating screen, liquid nitrogen tank, etc (1) How it works The super cold pulverizer system takes liquid nitrogen as the cold source, the crushed materials are brittle and easy to be crushed by cooling at low temperature, and then enter the mechanical pulverizer cavity through the high-speed rotation of impeller The materials and blades, toothed discs, materials and materials are repeatedly impacted, collided, sheared, rubbed and other comprehensive effects are achieved The crushed materials are screened by air flow The stage machine is classified and collected: materials that do not meet the fineness requirements are returned to the bin for continuous grinding, and most of the air-conditioner is returned to the bin for recycling (2) Features in the process of material crushing, the cold source of the super cold pulverizer system forms a closed-circuit circulation system, which makes full use of energy and saves energy consumption: the temperature of the cold source used for crushing can be reduced to minus 196 degrees; according to the temperature of the material's embrittlement point, the temperature can be adjusted and controlled during the crushing process, and the Zui preferred crushing temperature can be selected to reduce energy consumption: the crushing fineness can reach 10-700 degrees Objective, even achieve micron μ fineness: use liquid nitrogen as grinding medium, achieve ultra-low temperature grinding, material explosion-proof, anti-oxidation and other comprehensive effects 2 Scope of application: This super cold crusher system is used for all kinds of materials that can not be crushed under normal temperature, widely used in various chemical, petrochemical, machinery, ship, automobile, electronic industry, clothing, coating, printing, engineering plastics, rubber, thermoplastic materials, hot melt adhesive, nylon, polyester, polypropylene, polyethylene Food industry (chili powder), Chinese and Western medicine, nylon, polyester, hot melt adhesive, various engineering plastics, polyethylene, polyvinyl alcohol, polystyrene (PS), thermoplastic elastomer, TPU, general plastics, HDPE, polypropylene, thermosensitive adhesive, PA1010, LDPE, clothing hot melt adhesive, decorative powder coating, nylon 66 , medicine, nylon 11, EVA, nylon 6, nylon 12, plastic, rubber, PPT, pet, TPU, ABS, functional anticorrosive powder coating, 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: engineering modified products of general plastics (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 masterbatch and color masterbatch: such as White Masterbatch and other color masterbatch; functional masterbatch, coloring masterbatch, pigment dye, thermoplastic elastomer, engineering plastics, etc And so on 3 Main technical parameters (1), diameter of pulverizer working chamber φ 423mm (2), power of pulverizer: 37KW (total power: 49KW) (3), working medium: liquid nitrogen (4), working temperature: 0 ° to - 196 ° C (adjustable) (5), pulverizing fineness: 10-700 mesh (can reach micron μ) 4 Process configuration of complete set of equipment of ultra cold pulverizer Liquid nitrogen tank, bin, mechanical crusher, induced draft fan, primary cyclone discharge, secondary cyclone, vibrating screen Shanghai Pudong Gaoqiao testing machine factory Co., Ltd.: Yang Jiansen:: gqfsj @: Address: no.509, gaodongxin Road, Gaodong Town, Pudong New Area, Shanghai 200137
