The Hengci CXJ series fully automatic dry drum magnetic separator uses high-performance neodymium iron boron magnets with a magnetic field strength of up to 12000GS. Equipped with a vibrating feeder, it ensures uniform material distribution and superior iron removal. It can be configured with single, double, or multiple drums to meet different purity requirements.
Those in the abrasives, refractory materials, and non-metallic mineral processing industries know how crucial dry powder iron removal is.
Incomplete iron removal leads to lower product prices; old-fashioned electromagnetic separators incur exorbitant electricity bills and are prone to coil burnout. Is there a device that can efficiently remove iron without the hassle of daily maintenance?
Our CXJ fully automatic dry drum magnetic separator is specifically designed for dry powders. Available in single-drum to triple-drum configurations, it's crucial that it uses permanent magnets to generate a strong magnetic field without electricity!
How strong is the magnetic field?
The fully automatic dry drum magnetic separator features a proprietary internal magnetic circuit design, using neodymium iron boron (NdFeB) magnets as the magnetic source. This material boasts extremely high magnetic field strength and strong attraction, effectively capturing even the smallest iron impurities in the powder. Whether it's coarse or fine powder, a single pass through the machine results in a dramatic decrease in iron content.
Because it uses permanent magnets, there are zero electricity costs, zero risk of coil burnout, and zero maintenance—it can be used continuously once installed, and the electricity savings over a year could buy several machines.
Uniform feeding is key to iron removal.
What's the biggest fear in dry powder iron removal? A material layer that's too thick, or a fluctuating feeding speed. The powder is swept past before the iron is attracted.
Therefore, our fully automatic dry drum magnetic separator is specially equipped with a uniform vibrating feeder. It ensures that the material enters the magnetic separation zone smoothly and evenly, like flowing water, without fluctuations. A thinner material layer means more contact between the magnetic drum and the powder, naturally increasing the iron removal rate. Furthermore, the feeding speed can be adjusted freely, finding the most suitable setting for both coarse and fine materials.
These industries all use:
- Abrasives: Brown fused alumina, white fused alumina, silicon carbide—the cleaner the iron removal, the better the grinding effect.
- Refractory materials: Iron impurities reduce refractoriness, requiring strict control.
- Non-metallic minerals: Dry purification of quartz sand, feldspar, and kaolin to improve product quality.
- Chemical raw materials: Various powder materials to ensure the purity of downstream products.
- Food and feed: Iron impurities in grains and feed affect food safety.
Let's do a simple economic calculation
Previously, using old-fashioned electromagnetic separators cost tens of thousands of yuan in electricity annually, and coils needed frequent replacement. Switching to our fully automatic dry magnetic drum separator:
Zero electricity cost—the permanent magnet consumes no electricity.
Zero labor—fully automatic continuous operation, no human supervision required.
Almost zero maintenance cost—no easily worn parts, lasting for many years.
Finally, a few words:
If you are also looking for a high-efficiency, energy-saving, and maintenance-free dry powder iron removal device, consider the CXJ type fully automatic dry magnetic drum separator.
Single-cylinder systems offer high throughput, double-cylinder systems remove iron more thoroughly, and triple-cylinder systems can essentially remove stubborn iron impurities three times. Based on your production volume and precision requirements, we can help you choose the most suitable model.
After all, choosing the right equipment is crucial for getting a good price for your products, which is the real way to save money.
