Who is behind PTMS
PTMS is the brand of FOSHAN POWTECH TECHNOLOGY COMPANY LIMITED, founded in 2017. We manufacture in a 5,000 m² plant in Foshan, Guangdong, with in-house coil winding and assembly. Every unit runs a 24-hour burn-in test before shipment, the separators are CE certified, and we export to Southeast Asia, India, Africa and the European Union with English documentation. We also build to your own brand (OEM / private label), with a minimum order quantity set case by case.
What a dry magnetic separator does
A dry separator removes magnetic iron from free-flowing powder without water. The powder is fed onto a magnetised surface, the magnetic particles are held, and the clean material falls away under gravity. In our dry powder machines a vibrating device helps the iron release, and the magnetising current is switched off to discharge the captured iron. Typical feed materials are quartz powder, feldspar powder, bentonite, lithium battery cathode and anode materials, graphite and activated carbon. For wet slurries (kaolin, feldspar slip, ceramic glaze) you want a wet separator instead; see our wet separators.
Current model range: PT3A160 to PT25A600, plus PT1000
PTMS currently supplies the dry-powder electromagnetic separator series PT3A160, PT20A600 and PT25A600 (PT3A160 and PT25A600 are the two ends of the series, PT20A600 sits between them), and the PT1000 (the PTMS-1000 class). Only the PT20A600 has a datasheet published on our site so far; the other models are quoted with a datasheet on request, once we know your material and throughput.
| Model | Field strength | Max coil power | Cooling | Magnetic cavity | Yield (t/h) |
|---|---|---|---|---|---|
| PT3A160 | Datasheet on request | ||||
| PT20A600 | 2.5 T | 20 kW | Double cooling, water and oil | 600 mm | 2–4 |
| PT25A600 | Datasheet on request | ||||
| PT1000 | Datasheet on request | ||||
Your actual throughput depends on the material, so we confirm it against a sample. Overall dimensions, host weight and electrical details are in the datasheet we send with a quotation. The same PT models serve the lithium-battery and mineral powder lines; their individual datasheets are issued on request.
How to pick a size
- Throughput first. Give us the hourly rate (t/h or m³/h), the bulk density and how the powder flows. Material that moves too fast through the field is captured less well, so we size the chamber and field from throughput, particle size, iron content and target purity, with a working margin for peak load.
- Weakly magnetic iron needs field and gradient. Fine, weakly magnetic iron is why powder lines use an electromagnetic machine with an adjustable, strong field rather than a plain permanent magnet. If your iron load is light and the material is coarse and free-flowing, a permanent magnetic separator can be enough and uses no power.
- Plan for expansion. If feed rate varies or you will add capacity later, tell us now so we engineer for the maximum case.
What to send for a quote
A quotation from us normally names the recommended model and chamber type, the key specifications (field strength and duty rating), the unit price under your Incoterms, the production lead time and the packaging. To prepare it we need:
- Material type and particle size (and whether it is dry and free-flowing)
- Throughput in t/h or m³/h
- Current iron content and the target you need
- Destination port or country, and preferred payment method (we accept T/T and L/C)
- A sample if you can: a test on your own material lets us confirm the configuration before we finalise the offer
Standard models are usually produced and factory-tested within a few weeks; customised units take longer, and we confirm the delivery date in the proforma invoice. After delivery our engineers can be on site within 72 hours for commissioning and service, and OEM coils, matrices and IGBT/diode modules are stocked as spare parts.
Next step: send us your material details (or WhatsApp +86 139 2990 7491) and we reply with a matched model and a quotation. Our FAQ states that a test on a sample of your material comes first, and that no iron-reduction figure is quoted without a test.
