Magnetic Separation for Lithium Battery Powders
Permanent magnetic separators can be assessed for iron-contamination control in battery-material powders. Identify the actual cathode, anode or lithium-compound material and its flow properties before selecting equipment. Powder purification and battery-recycling metal recovery are different processes.
Define Material Identity and Acceptance Criteria
Specify the chemical identity and safety data of the powder, not simply “lithium powder”. Provide contaminant composition, size distribution and concentration. Agree on a sampling method and target limit with the process team; a separator listing does not establish battery qualification or explosion protection.
Assess Handling and Wear Sources
Review contamination introduced during storage, transport, mixing and conveying. Check product-contact compatibility and abrasion at the proposed location. Magnetic separation targets responsive particles; it does not chemically extract lithium or remove every dissolved impurity.
JH-LX Configuration for Powder Lines
JH-LX is the automatic-cleaning separator series; 06C-12000 is one configuration within that series. Magnetic-bar dimensions and magnetic strength can be customized. JH-QZ01 identifies the pneumatic assembly. Confirm the bar count, diameter and magnetic measurement conditions on the quotation and drawing rather than treating one configuration as the whole series.
Flowability and Cleaning Sequence
Review bridging, moisture and bulk density alongside throughput. Confirm the cleaning sequence, discharge route and dust-control interface. Automatic cleaning is a design feature, not a guarantee that every powder will flow without bridging or meet the same removal rate.
Testing and Scope of Performance Claims
For JH-LX, Jinhong has reported removal of iron impurities approximately 80 μm in diameter. This refers to the iron impurity, not the powder size, and must be assessed against the actual operating conditions. Do not transfer that figure to an untested battery powder. Provide representative samples and define the inlet/outlet sampling procedure before agreeing performance. Magnetic separation must not be described as a chemical leaching-purity result.
Application Review and Enquiry
Provide your material, contaminant details, throughput and installation drawing for a magnetic separation application review. Equipment options and related references are listed below.
Review powder flow and separator configuration
Compare JH-LX pneumatic self-cleaning separation with rotary magnetic separation for your powder flow and cleaning requirements. Provide material identity, moisture, throughput, dust-control arrangements and contaminant data for a configuration review.
The silica powder supply case is a separate dry-powder reference. Its customer history and equipment use must not be treated as battery-powder qualification or a guaranteed removal threshold.
