Rotary Atomizer wheel type AX
(patented) |
Spray drying technology plays an important role in the production of the next generation of batteries for electric vehicles and other high energy applications. Lithium-ion materials for Li-ion batteries - lithium iron phosphate (LiFePO4) and other - can be made using spray drying technology to achieve a more energy dense battery.
GEA Niro has demonstrated the applicability of the GEA Niro Rotary Atomizer, type AX (patented), for drying of such materials. In this application, a rotary atomizer offers a number of advantages that are in high demand by the market; it produces a very fine powder with a narrow particle size distribution ideal for further processing, and it does so consistently |
because it is inherently wear-resistant towards the abrasive lithium-ion materials being processed. This, in turn, implies
low maintenance requirements. The GEA Niro Rotary Atomizer, type AX, also has comparatively low energy consumption, and is very easy to adjust and operate. For solvent-based feeds, the spray drying plant can be designed as a closed-cycle plant where the complete drying unit is inertised to prevent dust explosions and to allow full recovery of the solvent.
