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.
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.
What about spare parts and lead time?
OEM coils, matrices and IGBT/diode are stocked; we keep your separator at full capacity with fast spare-part supply.
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.
