300 m Dense-Phase Transfer for LFP Powder with Ceramic Pipeline

Challenge

Spray-dried lithium iron phosphate needed long-distance transfer with low pipe wear and controlled metal contamination.

Solution

CYprocess designed a dense-phase blow-tank system with about 300 m conveying distance, ceramic-lined pipeline sections and downstream de-ironing.

Results

Long-distance transfer without open conveyors
Reduced wear via dense phase + ceramic pipe
De-ironing protects battery-grade purity
Stable continuous feed after spray drying

Project Details

Project background

After spray drying, LFP powder had to move a long distance across the plant. Dilute-phase dilute velocity would accelerate pipe wear; open mechanical transfer was unacceptable for dust and purity.

LFP production — LFP plants often need long enclosed powder routes

System design

A positive-pressure dense-phase system (typically 2–6 bar class air supply) moves high solids loadings at lower velocity. Ceramic pipeline sections protect against abrasion. De-ironing is installed before process use or packing.
