Lithium iron phosphate dryer project overview
Lithium iron phosphate is a new type of electrode material for lithium ion battery. It is characterized by large discharge capacity, low price, non-toxicity, and does not cause environmental pollution.
The performance of lithium-ion batteries mainly depends on the positive and negative materials, as lithium-ion battery cathode material of lithium iron phosphate, safety performance and cycle life is not comparable to other materials, which are also important technical indicators of power batteries. Lithium iron phosphate cathode material to make high-capacity lithium-ion batteries easier to use in series. To meet the need for frequent charging and discharging of electric vehicles. With non-toxic, good safety performance, raw materials from a wide range of sources, inexpensive, long life and other advantages, is a new generation of lithium-ion batteries ideal cathode material.
Our company in many years of spray dryer design and manufacture of accumulated experience on the basis of new energy materials from the generation of lithium iron phosphate, involved in the study of this product, through a large number of customer projects in the field, and constantly summarize, improve and optimize the spray drying of lithium iron phosphate has formed a mature design, manufacturing, construction, control and operation experience.
Working principle of lithium iron phosphate dryer
Spray dryer is the raw material liquid with atomizer dispersed into droplets, and the use of hot air (or other gases) and droplets in direct contact with the way to get a powdery product of a drying process. The raw material liquid can be a solution, emulsion or suspension, or a molten liquid or paste. The dried product can be made into powder, granule, hollow ball or agglomerate as required. Spray dryer is a drying process in which the raw material liquid is dispersed into droplets by an atomizer, and a powdered product is obtained by direct contact between hot air (or other gases) and the droplets. The raw material liquid can be a solution, emulsion or suspension, or a molten liquid or paste. The dried product can be made into powder, granule, hollow ball or agglomerate according to the need.
High-speed centrifugal spray dryer for battery materials is applied to the drying production of water-soluble liquid material of lithium iron phosphate cathode material for lithium batteries, adopting high-speed centrifugal spray atomization technology, while realizing continuous drying production, it obtains micro-spherical particles of uniform particle size, compact structure and good fluidity, to a large extent, high-speed centrifugal atomization technology, which can effectively improve or increase the stacking density of the cathode material lithium iron phosphate, so that its monomer To a large extent, high-speed centrifugal atomization technology can effectively improve or increase the stacking density of lithium iron phosphate anode material, so that its monomer particles can reach the quality requirement of 3~5um and the moisture content of finished product is 0.5%, and the application of magnetic filtration technology effectively avoids the adulteration of iron ions in the process of production, so as to achieve the pure purpose of the material and maintain the electrical conductivity of anode material. The recycling of waste heat and gas can achieve the production purpose of energy saving and emission reduction, which is in line with the national advocacy of energy saving and emission reduction, and the transformation of low-carbon production mode. In order to maintain production safety, this machine adopts pulse dust removal cooling protection technology, which realizes cooling protection safety interlock under intelligent control operation. The comprehensive application of innovative technology, for China's new energy lithium battery cathode material industrial production, to provide basic equipment and technical support, is the more ideal new material drying equipment.
