The airflow milling work is that compressed air is frozen, filtered, dried, and several nozzle spraying through two-dimensional or three-dimensional arrangement forms an ultrasonic speed gas flow into the pulverizing chamber, and the gas flow impact can make the material are fluidized. , The accelerated material is combined in several nozzles, which produces severe collision, friction, and shear, and ultrafine pulverization of the particles.Lithium iron phosphate is a new type of lithium ion battery electrode material. The lithium iron phosphate hypergantheur current pulverized in Shandong Erfa can achieve ultra-fine pulverization to 1-5 microns to 1-5 microns, and achieve accurate grading.
The lithium iron phosphate super micro-gas flow pulverizer is the problem of our company in combination with the production of lithium iron phosphate powder to produce the problem of lithium iron phosphate production process, specially developed Lithium iron phosphate preparation dedicated production line, this production line is a method and apparatus for simultaneous use of high-temperature dry nitrogen gas clipping system, simultaneous method and apparatus for ultrafine pulverized and dry lithium iron phosphate in a nitrogen closed cycle system; Sintering system, crushing system, packaging system for full enclosure. Lithium iron phosphate is closed in sintering, pulverizing, packaging, etc., the pulverization system is provided with a gas flow pulverizer, using high temperature dry nitrogen as a pulverized gas source, and lithium iron phosphate is dried, and lithium iron phosphate is pulverized and Dry simultaneously. This system solves the problem of staged products in the production of lithium iron phosphate, which saves energy and reduces production costs.
The new phosphate hyperthermithic current pulverizer is a special production line system integrating high temperature nitrogen protection airflow pulverization and drying systems. The high-temperature drying gas is used to ultrafine pulverizing the lithium cell phosphate of lithium battery positive electrode material, and the material surface water is transferred and instantaneously drying with the ultrasonic air flow spurting field, and the lithium iron phosphate is super micro-pulverization. + Trace moisture drying integrated. When the feed moisture is 3000 ppm and the feed particle size D50 = 20-30 um, the finished particle size D50 = 0.6-2 um, D100 = 4-10 um, and the finished moisture is 200-500 ppm after pulverizing drying integrated. As an example, the production line of 3000T was taken, the unit tonne energy consumption was 650 yuan to 900 yuan / T, and the amount of nitrogen was 410-600 nm3 / h. More than 450-5.5 million energy consumption per year than traditional double conical drying or roller furnace drying ultra-microfinyuan. At the same time, the ultra-fine pulverization and drying process realize the full closed road gas flow delivery system, which is generated without dust pollution. The process realizes the effective combination of lithium iron phosphate ultrafine pulverization technology and micro-water control technology for ultra-fine particles, effectively solves the life and safety challenge of the use of lithium batteries, is a lithium battery positive material phosphate hypertrophy A major breakthrough in the field of system.
