Lithium iron phosphate spray drying unit

Lithium iron phosphate spray drying unit

Lithium iron phosphate spray drying unitSuitable for liquid and slurry battery materials such as lithium iron phosphate and lithium titanate.

Spray drying is a method of systematic technology applied to material drying. This method has simple production equipment and an easy to implement process. It can quickly dry solutions and emulsions into powder or granular products, eliminating the need for evaporation and washing processes, improving product production efficiency, and saving costs, Realize large-scale production.The spray drying method has been widely used in the preparation of lithium battery materials. Through spray drying tests on different positive and negative electrode materials (lithium iron phosphate, lithium carbon, etc.) in recent years, Combined with the continuous new requirements from users and the absorption of new foreign technologies, we are able to choose and optimize process design to produce high-quality battery materials in the most energy-efficient and cost-effective way possible.

Lithium iron phosphate spray dryerFeatures:

The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, it can evaporate instantly95%~98% moisture content, drying time only takes a few seconds, especially suitable for drying heat sensitive materials.

The product has good uniformity, fluidity, and solubility

Solution, high product purity, and good quality.

The production process is simplified and the operation control is convenient. For moisture content40-60% (up to 90% for special materials) of liquid can be dried into powder products in one go, without the need for crushing and screening after drying, reducing production processes and improving product purity. The particle size, bulk density, and moisture content of the product can be adjusted within a certain range by changing the operating conditions, and both control and management are effective.

After filtering and heating, the air enters the top air distributor of the dryer, and the hot air enters the drying chamber uniformly in a spiral shape. The liquid material passes through the high-speed centrifugal atomizer at the top of the tower (rotating) The spray becomes a very fine mist like liquid bead, which can be dried into finished products in a very short time when it is in parallel with hot air. The finished product is continuously output from the bottom of the drying tower and the gas-solid separator, and the exhaust gas is discharged by the induced draft fan.
