Frequently asked questions
The questions buyers ask before they order.
How low can your separator bring the iron content?
It depends on your feed material and model. Send us a sample and we run a free test, then report the actual Fe reduction your line can expect.
Which machine suits lithium battery slurry iron removal?
The 40A600 slurry electromagnetic separator is positioned for lithium electrode slurry. Dry cathode/anode powder uses PT3A160, PT20A600, PT25A600 and PT1000. Datasheet for 40A600 comes with a custom quote after a slurry review or free sample test.
Can it be connected to my existing production line?
Yes. We design in-line pipe, drawer, rotary and U-type units that drop into existing pipelines with zero extra floor space.
Do you ship internationally and provide commissioning?
We export to Southeast Asia, India, Africa and the EU, with 72-hour on-site service and English documentation.
How do I get a free sample test?
Send 2–5 kg of your material. We run the test and issue a report within 5 days showing the iron removed.
What you can count on
Four commitments we apply to every separator we build — from factory testing to commissioning at your plant.
24-hour burn-in before shipment
Every separator runs a full 24-hour burn-in test in our plant, so performance issues are found before the unit ships.
Free sample test with your material
Send us your material. We run it on the matched machine and return the test result before you commit to an order.
Engineers on site within 72 hours
Commissioning and service support can reach your plant within 72 hours, with English documentation included.
CE certified and patent-backed
Our separators are CE certified and supported by technical patents; we supply the certificates your market requires.
