LFP Cathode Material Production Line — Turnkey Powder Handling with Zero Iron Contamination
Closed-loop dense-phase conveying, ±0.1% loss-in-weight batching and automated packaging, engineered end-to-end for lithium iron phosphate plants.
Overview
One Partner, One Responsibility — From Raw LFP to Sealed Saggers
Lithium iron phosphate is abrasive, iron-sensitive and unforgiving of contamination. A single stray metal particle downstream can mean a rejected cell batch. Bulk Pro engineers the whole flow — receiving, conveying, batching, mixing, iron removal and packaging — as one integrated system, so no interface is left to chance.
Every station reports into a single DCS/MES layer: recipes, weights, material lots and alarm history are captured automatically, giving your QA team a complete batch genealogy for every sagger that leaves the line.
- Closed-loop conveying — no open transfers, no dust in the workshop
- Zero-iron design: ceramic / PU / PTFE linings + high-gauss magnetic traps
- ±0.1–0.2% loss-in-weight batching across all solid raw materials
- FAT with your own LFP material at our Hefei base before shipment
Process Flow
Six Engineered Stages, One Continuous Closed Loop
Layout and capacities are configured to your building, PSD and throughput target.
Receiving & Unpacking
FIBC and small-bag stations with dust-tight hoods and integrated collection.
Dense-Phase Conveying
Low-velocity closed-loop transfer preserving particle morphology.
Loss-in-Weight Batching
Gravimetric dosing of LFP, conductive carbon and binders at ±0.1–0.2%.
Mixing & Homogenizing
Ploughshare and high-speed mixers with recipe-driven sequences.
Iron Removal & Screening
Multi-stage magnetic separation plus security sieving before packing.
Sagger Filling & Packing
Automatic filling, weighing, checkweighing and palletizing.
Why Bulk Pro for LFP
Four Engineering Barriers, Solved on Every Line
Zero Iron Contamination
Ceramic / PU / PTFE-lined contact parts, long-radius bends and high-gauss magnetic traps keep Fe / Cu / Zn out of your product stream.
Closed-Loop Clean Conveying
Dense-phase transfer at low velocity — minimal attrition, minimal dust, stable tap density batch after batch.
High-Precision Batching
Loss-in-weight feeders hold ±0.1–0.2% across recipes, with automatic refill without stopping the batch.
Full Batch Traceability
DCS + MES genealogy from raw-material lot to sealed sagger — Battery-Passport-ready data exports.

LFP Line — Engineering FAQ
Questions Cathode Plant Directors Ask Us First
Every product-contact surface is 304/316L stainless with optional ceramic, PU or PTFE linings, and high-gauss magnetic separators are installed at every critical transfer point. Pneumatic bends use long-radius designs with wear-resistant liners, and each line passes magnetic-susceptibility validation with the client's own LFP material before shipment.
Single-line capacities from 500 to 20,000 kg/h are engineered per project, using parallel loss-in-weight batching trains and dense-phase conveying loops. The DCS layer balances load automatically across batching stations, so capacity can be expanded in stages without redesigning the conveying backbone.
Yes, with validated clean-in-place sequences and full batch genealogy in the MES layer. Cross-contamination risk is controlled by dedicated transfer lines or purge routines, documented shift records, and magnetic-trap inspection checkpoints between campaigns.
