Spray Drying Of Anode And Cathode Materials Of Lithium Batteries

QZR high-speed centrifugal spray dryer is used for the dry production of water-soluble liquid materials of lithium battery lithium iron phosphate positive electrode materials. It adopts high-speed centrifugal spray atomization technology, and the drying time only takes tens of seconds. While achieving continuous drying production, uniform particle size The micro-spherical particles with compact structure and good fluidity, to a large extent, the high-speed centrifugal atomization technology can effectively improve or increase the bulk density of the cathode material lithium iron phosphate, so that the monomer particles can reach 3 to 5um and the finished product With a quality requirement of 0.3-0.5% moisture content, magnetic filtering technology is applied to effectively avoid the incorporation of iron ion impurities in the production process, to achieve the purpose of material purity, and to maintain the conductivity of the positive electrode material. Because the exhaust gas temperature is greater than 120 degrees, direct emissions are wasteful, and the recycling of waste heat gas can also achieve the production purpose of energy saving and emission reduction, in line with the change in energy saving and emission reduction and low carbon production methods advocated by the state. The comprehensive application of innovative technologies provides basic equipment and technical support for the industrial production of new energy lithium battery cathode materials in China. It is an ideal new material drying equipment.
