The MAG SPRING Automatic Powder Magnetic Filter is a state-of-the-art automatic powder magnetic separator designed to deliver high-capacity, low-intervention ferrous removal for dry powder production lines. Featuring a magnetic surface strength of 9000–13000 GS, this unit processes up to 24 m³/h, providing a reliable solution for industries where even trace iron contamination can compromise product integrity.
Food & Beverage: Ensuring contaminant-free food powders (milk, starch, spices) where regulatory compliance demands robust magnetic separation.
Pharmaceutical & Nutraceutical: Raw-material purity for tablets/capsules where metal contamination can lead to recall or failure.
Chemical Industry: Removal of ferrous inclusions from PVC, carbon black, catalysts where downstream equipment damage or product quality may suffer.
Battery Industry: In precursor compounds, cathode/anode powders or electrolytes, even micro-iron contamination can impair performance or safety.
Ceramics & Plastics: To boost final product quality by eliminating metal specks that cause visual defects
The MAG SPRING Automatic Powder Magnetic Filter is an advanced ferrous removal system designed for continuous, high-volume powder processing. Engineered with powerful rare-earth magnets up to 14000 Gauss+/-500Gs, this automatic magnetic separator ensures precise, efficient removal of fine iron contaminants from dry powders such as milk powder, PVC resin, battery precursors, and chemical additives.
Built for fully automated operation, it minimizes manual cleaning, reduces downtime, and ensures consistent product purity across industries requiring strict hygiene and precision — from food and pharmaceuticals to chemicals and battery materials.
In modern manufacturing of food powders (such as milk powder, starch, chili powder), chemicals (PVC resin, carbon black), pharmaceuticals, and emerging high-tech sectors like lithium-battery precursor compounds, ferrous impurities are a hidden cost driver. They may cause product quality rejection, equipment wear, contamination risk, and regulatory non-compliance. Traditional manual magnets or gravity separation are often insufficient for high-throughput production and sanitary requirements. Customers frequently complain: “We still find tiny iron particles after screening”, “Our manual magnet stage causes downtime”, or “Our product failed purity specs due to metallic contamination”.
Our automatic powder magnetic separator provides a maintenance-free, high-efficiency solution with continuous iron discharge, helping manufacturers eliminate contamination risks while maintaining maximum productivity.
Common customer challenges we solve:
Iron contamination after sieving or pneumatic conveying
Downtime during manual magnet cleaning
Product purity not meeting quality or regulatory standards
With this high-capacity magnetic filter, all these pain points are solved automatically.

Compact structure – easy integration into existing powder conveying lines
Low maintenance cost – fully enclosed, long service life
Improved product quality & equipment protection
Q1. What’s the difference between manual and automatic powder magnetic filters?
Manual filters require production stoppage for cleaning. The automatic type removes ferrous contaminants continuously using motorized scraping or rotation, drastically reducing downtime.
Q2. What kind of powders can this magnetic filter handle?
It’s designed for dry, free-flowing powders such as PVC resin, starch, milk powder, carbon black, and lithium battery precursors.
Q3. How strong is the magnetic field?
Surface magnetic intensity ranges from 9000 to 13000 Gauss, ensuring reliable ferrous removal even for fine metal dust.
Q4. Can it be customized for high-temperature or chemical environments?
Yes. We provide high-temperature versions up to 250 °C and corrosion-resistant options with 316L stainless steel and PTFE seals.
Q5. Does it meet food or pharmaceutical standards?
Absolutely. The filter can be built in sanitary grade with mirror-polished interiors, silicone seals, and hygienic welding to meet FDA / GMP compliance.
