Lithium iron phosphate efficient production line

Product details


Lithium iron phosphate efficient production line





Professional customization of lithium iron phosphate crushing, sorting, drying, packaging and conveying equipment complete production line


This system is my company according to the requirements of lithium iron phosphate powder preparation of manufacturers in the production of the lithium iron phosphate the problems in the process, special research and development of preparation of lithium iron phosphate is special production line, this line is a kind of high temperature drying nitrogen closed cycle system, the superfine grinding and drying the lithium iron phosphate in nitrogen gas in closed cycle system and method and device; The sintering system, crushing system and packing system of producing lithium iron phosphate are all closed. Lithium iron phosphate is sealed and transported in sintering, crushing, packaging and other processes; The crushing system is equipped with an airflow crusher. High-temperature dry nitrogen is used as the crushing gas source, and the lithium iron phosphate is sprayed to dry instantaneously, so that the crushing and drying of lithium iron phosphate are carried out at the same time. This system solves the problem of continuous drying of periodic products in the production process of lithium iron phosphate, saves energy and reduces production cost.

       The new lithium iron phosphate production line is a special production line system which integrates the high temperature nitrogen protective airflow crushing and drying system. High temperature dry gas was used to conduct ultramicropulverization of lithium iron phosphate as the cathode material of lithium battery. Meanwhile, the surface water of the material was heat and mass transfer and instant drying by supersonic airflow swirling jet field, realizing the integration of ultramicropulverization of lithium iron phosphate + trace water drying.


When the feed water content is 3000PPM and the feed particle size d50=20-30um, the finished product particle size d50=0.6-2um, d100=4-10um and the finished product moisture content 200-500ppm can be achieved after the integration of grinding and drying. Take the production line with an annual output of 3000T as an example, the energy consumption per ton is 650-900 yuan /T, and nitrogen consumption is 410-600nm3 /h. Compared with the traditional double-cone drying or ultra-fine grinding process with roller hearth drying, the annual energy saving is 4.5-5.5 million yuan.


At the same time, the whole closed-circuit airflow conveying system is realized in the process of ultramicrogrinding and drying. This process realizes the effective combination of ultramicropulverization technology of lithium iron phosphate and micro-water control technology on the surface of ultramicroparticles, effectively solves the current problems that restrict the service life and safety of lithium batteries, and is a major breakthrough in the field of preparation of ultramicropowder of lithium iron phosphate as the anode material of lithium batteries.
