FAQ’s: Lithium Battery Thermal Processing
Why is calcination so critical for LFP and NMC materials?
Calcination determines phase formation and material structure – both essential for achieving required electrochemical performance.
Can rotary calciners handle highly reactive or oxygen-sensitive materials?
Yes. HP Process calciners can operate under inert or controlled atmospheres, preventing contamination or unwanted reactions.
How does thermal drying support black mass recycling?
Removing moisture and solvents early improves separation efficiency and protects downstream equipment from corrosion or fouling.
Are rotary systems suitable for ultra-fine or dust-prone battery materials?
Absolutely. Our systems are engineered with advanced seals, dust control features, and custom internals for fine powders.
How do custom internals improve heat transfer?
Lifters and mixing elements uniformly expose particles, ensuring consistent thermal contact and preventing degradation.
