Process Requirements

Typical materials: Lithium battery powders, graphite, carbon black, conductive additives, biomass pellets and mineral precursors.

Application challenge: Fine and abrasive materials may require strict contamination control, wear protection, dust containment and stable dosing.

FUWEI recommendation: Choose stainless, non-metal-contact or coated construction with project-specific seals, clearances and drive protection.

Recommended Valve Configurations

Contamination	Metal-contact or non-metal-contact configuration according to purity target
Wear	Tungsten carbide, PTFE or selected protective treatment
Sealing	Dust-tight shaft sealing and pressure-balanced arrangement
Automation	Variable-speed drive for controlled feeding and dosing

Recommended FUWEI Products

Final model selection should confirm material name, bulk density, particle size, moisture, required capacity, temperature, pressure difference, flange standard and motor requirement.
