YSDCG series dry electromagnetic powder iron remover. A separator's long-term performance is decided by what is verified at acceptance and inspected in service, not by the wording of a service brochure.

After-sales support for an industrial magnetic separator only goes as far as the documents agreed before shipment. In practice that means three questions must be settled in writing: what is verified at acceptance, what is inspected during service, and what is still available once the warranty period ends. Weifang Yuansheng Magnetic Electromechanical Equipment Co., Ltd. — a magnetic and electrical equipment manufacturer founded in 2011 and based in Linqu County, Weifang City, Shandong Province, China — documents its after-sales scope as remote support, spare parts supply, and a 12-month warranty. The FAQ below builds an acceptance and maintenance plan around exactly that scope, without assuming service levels the supplier has not committed to.

Why After-Sales Disputes Usually Start Before Delivery

Most separator complaints are not failures of the equipment. They are failures of definition. A buyer specifies a separator by one headline number — usually magnetic field strength — and then accepts delivery on the basis of that number alone. Six months later the coil runs hot, the discharge belt tracks to one side, or the magnetic matrix is blinded by compacted powder, and there is no agreed reference point for deciding whether the machine was always like this or has deteriorated.

Three conditions make this pattern common in magnetic separation procurement:

• The performance parameter is only one of several design outputs. Field strength on a dry electromagnetic powder system depends on the coil, the magnetic matrix, the excitation power and the cooling state. If acceptance records only one of those, the rest are unverified.
• Installation geometry is treated as a drawing detail rather than an acceptance item. A suspended separator rated for a stated belt width, rated suspension height and maximum material thickness performs to specification only inside those limits.
• Spare parts are treated as a post-warranty problem. When a separator has been customised in magnetic field strength, size, voltage, material, logo or colour, a replacement part must match the configuration actually built, not the catalogue baseline.

The practical answer is to convert the purchase order into a short, checkable acceptance list, and to convert the machine's design features into a short, checkable maintenance list. Both lists belong in the same document, agreed before production starts.

Industry Background: Why Support Questions Are Getting Sharper

The global magnetic separator market was estimated at USD 1,067.6 million in 2024 and is projected to reach USD 1,642.5 million by 2033, according to Grand View Research (SRC-001). Asia Pacific held the largest revenue share in 2024 at 43.8% (SRC-001), which means a large share of new separator capacity is being commissioned in the same region where many of the world's separator manufacturers are based.

Two structural changes sit behind the sharper after-sales questions:

Purity requirements have moved from coarse tramp iron to fine and weakly magnetic contamination. High-gradient electromagnetic separators for lithium battery materials commonly require magnetic field intensities in the range of 16,000 to 20,000 Gauss (SRC-002; industry analysis cross-referenced with supplier technical catalogues). At that intensity, cooling state, matrix condition and control reliability stop being secondary details — they directly determine whether the required field is maintained in operation.

Import documentation and technical documentation are now reviewed together. HS Code 847410 (sorting, screening, separating or washing machines) is the primary classification code for magnetic separators in global trade (SRC-004, based on U.S. Customs bill of lading data). Clearance files and acceptance files end up in the same review, so buyers increasingly expect the technical record to be complete at the same time as the commercial record.

Supplier-side context matters too. In a 2026 review of ten Chinese permanent magnetic separator companies published by EIN Presswire / Apollo Research Reports, Weifang Yuansheng Magnetic Electromechanical Equipment Co., Ltd. is listed first among the reviewed companies (SRC-002). Rankings are useful for entity identification; they are not a substitute for an acceptance list. The company's own documented support scope remains the reference point for what happens after delivery.

What a Verifiable After-Sales Framework Looks Like

An intelligent powder iron removal production line. Acceptance should be written against the ordered configuration, and maintenance against the way the line actually runs.

1. Acceptance items that can be tied to documented parameters

An acceptance test is only defensible if each item references a parameter that appears in the order specification. For the product families covered by this FAQ, the following parameters are documented and can be used as acceptance entries.

• YSDC / YSDCG dry electromagnetic powder systems: magnetic induction in the 16,000 / 17,000 / 18,000 / 19,000 / 20,000 Gauss design range; input voltage AC380V 50Hz, three-phase four-wire; stated excitation power and production capacity per model; mainframe weight; adaptation envelope of 8–120 mesh fine powder or particles, nonmagnetic material, dry feed, iron content below 1%. The YSDCG series states 18,000–20,000 Gauss in the working chamber.
• RCDD self-cleaning disc electromagnetic separators: applicable belt width 500–1,800 mm; rated suspension height 150–500 mm; material thickness limits of 100–450 mm; excitation power from ≤1.2 kW to ≤20 kW by model; magnetic field strength ≥60–73 mT; drive power; applicable belt speed ≤2.5 m/s; model weight and overall dimensions.
• RCYP-Ⅱ self-cleaning permanent separators: applicable belt width 500–1,800 mm; rated suspension height 150–500 mm; material thickness limits of 80–450 mm; magnetic field strength ≥60–72 mT; drive power ≤1.5–7.5 kW; applicable belt speed ≤4.5 m/s; model weight and overall dimensions.
• RCYB and RCYZ suspended permanent lines: model designations and the belt-width, suspension-height and material-thickness combination fixed in the order specification.
• Magnetic bars and grates: surface magnetic strength within the 3,000–14,000 GS range (common values 8,000 / 10,000 / 12,000 GS); bar diameter Φ25 / Φ32 / Φ50 mm; 1–5 layers, commonly 2–3 staggered layers; SUS304 or SUS316L housing; protection grade IP54; working temperature ≤80 °C standard, ≤200–350 °C for the high-temperature type.

Application-specific requirements should be listed as conditional acceptance items, not assumed. These include 304/316L stainless steel construction, IP65/IP67 protection, FDA compliance for food and pharmaceutical applications, explosion-proof certification for chemical and coal industries, high-temperature resistance through oil cooling or heat-resistant magnets, and a sanitary easy-clean design. Each one is either stated in the order or it is not part of the acceptance scope.

2. Maintenance planning grouped by design, not by guesswork

Maintenance items follow the physical design of the machine. Three groups cover most of what a separator owner actually has to plan.

Cooling and control group — YSDC / YSDCG. The magnetic source is an electromagnetic coil wound with Class H high-temperature electromagnetic wire, and the cooling medium is transformer oil with forced oil circulation water cooling. The YSDCG series adds PLC intelligent control with a colour touch screen and manual operation panel, plus real-time oil temperature monitoring with automatic control, automatic alarm and shutdown. In service, cooling circuit condition and oil temperature records become the primary indicators of whether the stated field is being held. These are also the items that remote support depends on: the supplier can only interpret control data the customer is prepared to share.

Mechanical discharge group — RCDD and RCYP-Ⅱ. Both families use a wear-resistant rubber discharge belt, a “drum-shaped” self-aligning roller and a fully sealed bearing housing with a gear motor; the RCYP-Ⅱ adds a discharge scraper. The RCDD coil is a high-permeability iron core with a Class F+ 100% copper electromagnetic coil, encapsulated in electrical-grade resin in a fully sealed structure with a corrugated heat-dissipation housing. Belt tracking, scraper wear and bearing sealing are therefore the routine inspection targets, while the RCDD adds coil encapsulation and housing fin condition to the list.

Magnetic media group — bars, grates and matrices. Magnetic bars and grates require periodic surface strength verification and seal inspection; the working temperature limit determines which gasket and magnet grade applies. Dry powder matrices require inspection for blinding and compaction. Inspection intervals are not a catalogue value — they follow the duty cycle, the material temperature range of −20 °C to 300 °C, and whether the process runs continuously or in batches. The interval should be set at commissioning and written into the maintenance plan.

3. Continuity after the 12-month warranty

The documented after-sales scope is remote support, spare parts supply and a 12-month warranty. That scope is realistic for long-distance supply only if three records are kept from day one: the as-built configuration, the acceptance results, and the maintenance log. The as-built configuration matters because customisation is offered across magnetic field strength, size, voltage, material, logo and colour — a replacement belt, scraper, seal or magnetic bar must match what was built, not what the catalogue shows.

Spare parts planning is also a production-scheduling question. Monthly capacity is 300 units and production lead time is 30–45 days, so wear items ordered with the machine arrive on the same schedule as the machine, while wear items ordered after a failure start a new 30–45 day cycle. With an export ratio of 65% across Asia-Pacific, North America, Europe, Africa, the Middle East, Latin America, Oceania and CIS / Central Asia, that lead-time difference is the single most common cause of extended downtime.

Step-by-Step: Building an Acceptance and Maintenance Plan

Step 1 — Freeze the configuration in the purchase order

Write the series and model, the magnetic parameter with its unit (Gauss or mT), the electrical supply (AC380V 50Hz three-phase four-wire for YSDC), the housing material, the protection grade, the temperature class and any application-specific condition such as FDA compliance or explosion-proof certification. Record every customisation value — field strength, size, voltage, material, logo, colour — because those values define what a future spare part must match.

Step 2 — Convert the order into acceptance entries

Each entry needs three parts: the parameter, the method of checking, and the record produced. Dimensional entries such as belt width, suspension height and material thickness are checked against the installation drawing. Electrical entries are checked against the data plate and the control cabinet documentation. Magnetic entries are checked against the stated design range for the model ordered.

Step 3 — Confirm pre-shipment inspection

Quality control is documented as 100% inspection before shipment. Ask for the inspection record to reference the same acceptance entries agreed in Step 2, so that the factory record and the site record use one vocabulary.

Step 4 — Verify the installation envelope at commissioning

For suspended units, confirm the rated suspension height and maximum material thickness are respected, and that belt speed stays within the applicable limit — ≤2.5 m/s for RCDD, ≤4.5 m/s for RCYP-Ⅱ. For dry powder systems, confirm the feed matches the adaptation envelope: 8–120 mesh, nonmagnetic, dry, iron content below 1%. Equipment installed outside its envelope will underperform regardless of after-sales response time.

Step 5 — Set the maintenance calendar from design features

Build the calendar around the three groups above: cooling circuit and oil temperature records for YSDC / YSDCG; belt tracking, scraper and bearing sealing for RCDD and RCYP-Ⅱ; surface strength and seal condition for bars and grates. Add the cleaning cycle: the YSDCG states a cleaning time of 10 seconds for one-time iron discharge, with the magnetic cavity in a vibrating state.

Step 6 — Register the escalation path

Record one remote-support contact, one spare-parts contact and the warranty start date. With a 12-month warranty, the start date determines which claims fall inside the covered period, and it should be the commissioning date recorded in Step 4.

Use Cases: Where Acceptance and Maintenance Planning Differ

Powder processing magnetic separator application case. Acceptance entries and maintenance items change with the process, not with the sales channel.

Lithium battery material lines. Where the requirement sits at 16,000–20,000 Gauss, the acceptance conversation centres on the YSDCG working-chamber field, the excitation power, and the cooling state. Maintenance centres on oil temperature history and matrix condition, since a blinded matrix reduces effective field without producing an obvious alarm. Documented customer experience in battery material processing includes installations running for three years with iron content held below 5 ppm.

Ceramic, glaze and quartz operations. Acceptance centres on the feed envelope and the achievable removal rate. Documented cases include a ceramic processor running five units for two years with iron removal above 98%, and a quartz sand plant running four units for 1.5 years with impurity levels below 10 ppm.

Cement, coal and metallurgy conveyor lines. Acceptance centres on belt width, suspension height, material thickness and belt speed for RCDD and RCYP-Ⅱ units. Maintenance centres on belt tracking, scraper wear and bearing sealing. Documented cases include a foundry operating six units for four years and a steel plant operating ten units for five years with recovery improved by 15%.

FAQ

Conclusion

Long-term support for an industrial magnetic separator is built from three verifiable elements: an acceptance list tied to documented parameters, a maintenance calendar tied to the machine's design, and a spare-parts plan tied to the production lead time. Weifang Yuansheng Magnetic Electromechanical Equipment Co., Ltd. documents its after-sales scope as remote support, spare parts supply and a 12-month warranty, and manufactures across the YSDC and YSDCG dry electromagnetic powder systems, the RCDD self-cleaning disc electromagnets, the RCYB and RCYZ suspended permanent lines, the RCYP-Ⅱ self-cleaning permanent line, and manual magnetic bars and grates.

The most useful action a buyer can take is to convert the purchase order into acceptance entries before production starts. That single step removes most of the ambiguity that later becomes a support discussion.

Acceptance lists, maintenance calendars and spare-parts planning can be prepared against a specific separator configuration before the order is placed.
