Challenge: Maintaining Purity in Lithium Powder Processing
Lithium production demands consistency at every stage. Clean, uniform material is essential, and even microscopic magnetic contamination can compromise product purity and affect downstream processing quality.
In battery minerals production, reducing iron contamination from parts per million to parts per billion is critical.
At the German facility, the team needed a dependable way to improve powder purity without slowing operations. Their goal was stability. Fewer variables. A process they could trust to maintain tight purity specifications while preserving production flow.
Solution: High-Intensity Electromagnetic Separation for Fine Dry Powders
Bunting supplied a High Intensity Electromagnetic Dry Filter engineered for the fine dry separation requirements common in lithium and battery minerals processing.
The system generates a highly concentrated magnetic field capable of separating fine iron and paramagnetic minerals from dry powders, with background magnetic field strengths reaching up to 5,000 gauss.
Designed as a fully automated unit, the filter cycles through a defined cleaning process that maintains consistent separation performance while keeping production moving. Operators can adjust key operating parameters through the integrated HMI, allowing the system to be precisely matched to process requirements and purity targets.
The result is straightforward.
Clean material moves forward.
Product purity is maintained at demanding specifications.
Production rhythm stays intact.
Result: Consistent Lithium Powder Purity at Parts-Per-Billion Levels
With the High Intensity Electromagnetic Dry Filter installed, the operation achieved:
-
More reliable removal of fine magnetic contaminants
-
Improved consistency in processed lithium powder
-
Automated, repeatable cleaning cycles that support steady output
-
A stable and controlled process aligned with parts-per-billion purity targets in lithium production
For a facility where purity defines performance, this system adds confidence. Each shift now runs with greater assurance, supported by separation equipment designed to deliver consistent, high-purity material without disrupting production flow.
