5CX Magnetic Separator — Field Notes from the Line If you’ve ever picked tramp iron out of a product stream by hand (I have, and it’s no fun), you’ll appreciate a well-built overbelt magnetic separator . The 5CX from Shijiazhuang, Hebei, leans into that niche with a compact frame, stainless build, and a surprisingly strong 17,000 Gauss surface field. On paper it’s 5 t/h with a 0.75 kW drive; in the wild, it’s more forgiving than that, at least according to operators I trust. What’s trending, briefly Higher flux density with NdFeB arrays; 15–18 kG is becoming normal. Hygienic stainless frames for food and seed processors; easy-wash belt guards. Smarter checks: quick Gauss verification points and pull-test fixtures. Energy trim: small drives (≈0.75 kW) paired with efficient pulleys. Shorter lead times; 5CX quotes around 7 working days from order. Where it fits (and why) A overbelt magnetic separator straddles a conveyor and auto-ejects ferrous. Typical lines: grain and seed cleaning, glass cullet and plastics recycling, biomass, ceramics, limestone/aggregates before crushers, even wood pellet lines. Many customers say it’s the “insurance policy” before sensitive equipment like granulators or color sorters. 5CX key specifications Magnetic flux density (peak at belt face) ≈17,000 Gauss (real-world use may vary) Throughput 5 t/h (grain-like bulk, ≤80 mm burden depth) Drive power 0.75 kW, IEC-rated motor Construction Stainless steel frame, self-cleaning belt Magnet type Permanent NdFeB array, crossbelt Operating temp -10–60 °C (belt spec dependent) Production time 7 working days (typical) Origin Shijiazhuang City, Hebei Province, China Process flow, testing, and service life Flow: product rides the main belt; the overbelt magnetic separator spans it; ferrous rises to the field and is carried off by the cleaner belt to a discharge chute. Methods: aim for ≤80 mm burden depth; keep non-magnetic stainless hardware away from the magnetic face to reduce shadowing. Verification: Gauss readings at marked points; pull-test coupons; motor per IEC 60034; rotor balance per ISO 21940. Service life: magnets typically lose <3% over 10 years; belts are consumables (12–24 months depending on fines and abrasives). Customization options Belt widths, chute orientation (left/right), VFD speed control, food-grade belts, ATEX motor sets, quick-clean guards, ceramic wear liners. I guess the sweet spot is tailoring the belt speed to match residence time versus throughput. Vendor snapshot comparison (indicative) Vendor/Model Peak Gauss Power Lead time Warranty Notes 5CX (Beibu) ≈17 kG 0.75 kW ≈7 working days 12 months Stainless frame, compact footprint EU Brand X 15–16 kG 1.1 kW 3–5 weeks 24 months Strong CE/ATEX package Local Fabricator Y 12–14 kG 0.75–1.5 kW 2–4 weeks 6–12 months Budget-friendly, fewer tests Case notes Seed processor, APAC: swapped a plate magnet for 5CX. Reported 96% capture of ≥2 mm ferrous, belt load 4.8 t/h. Downtime dropped by ~30% (operator feedback). Glass recycler, EU: abrasive fines chewed the first belt in 10 months; upgraded to a ceramic-reinforced belt, now 18+ months service life. Sometimes the small tweaks matter. Compliance, testing, and QA trail Factory QA typically includes ISO 9001 processes, motor compliance to IEC 60034-1, rotor balance per ISO 21940, and magnetic verification with traceable Gauss meters. For stainless components, ASTM A967 passivation is a reasonable ask. In food plants, align with HACCP; in explosive atmospheres, specify ATEX build. Real-world pull tests and burden-depth checks seal the deal. Customer takeaways: “Easy install on our CEMA C conveyor,” one supervisor told me. Another liked the fast ship: “Order to dock in about a week.” Sounds about right.
