Manual-Clean Conveyor Tramp-Iron Removal

Disc-Type Suspended Electromagnetic Separator

Corvelan disc-type suspended electromagnetic separators are round electromagnets installed above a conveyor. They pull unwanted iron and steel pieces out of dry material moving on the belt. These unwanted metal pieces are often called ferrous tramp metal. Choose the documented manual-clean RCDB type when tramp iron appears only from time to time and a planned cleaning stop is practical.

Choose a different separator when the job changes. Use a self-cleaning suspended electromagnet when iron appears often or production cannot stop for cleaning. Do not use this RCDB separator for aluminum, copper, wet slurry, or weakly magnetic mineral recovery. Those jobs need another type of separator.

Choose Manual-Clean RCDBDry material moves on a conveyor, iron appears only from time to time, and the line can stop for cleaning.

Is This the Right Separator for Your Conveyor?

Use the manual-clean RCDB disc type when dry material moves on a conveyor, iron appears only from time to time, and a planned cleaning stop is practical. Use a self-cleaning suspended electromagnet when iron appears frequently or the line cannot stop for cleaning.

Occasional Iron + Planned Cleaning Stop

Use a manual-clean RCDB suspended electromagnet. This is the main application for the disc-type separator on this page.

Frequent Iron + No Routine Stop

Use a self-cleaning suspended electromagnet or cross-belt electromagnetic separator. We do not use the manual-clean RCDB as the first choice for this condition.

No Continuous Magnet Power Preferred

Review a suspended permanent magnet when it can reach the required iron target at the real working distance.

Aluminum, Copper, Wet Slurry or Mineral Recovery

Do not use this RCDB separator. These jobs need a different separation technology.

Product Basics

What Is a Disc-Type Suspended Electromagnetic Separator?

A disc-type suspended electromagnetic separator is a round electromagnet installed above a conveyor. It pulls unwanted iron and steel out of dry material moving on the belt. The RCDB type shown on this page is a manual-clean design, so captured metal is removed during a planned cleaning stop.

This type is also called a suspended round electromagnet, manual-clean suspended electromagnet or RCDB electromagnetic separator. It is different from a multi-disc mineral separator used for weakly magnetic mineral separation.

Use It for Conveyor Tramp-Iron Removal

Choose this equipment when the material is dry, moves on a conveyor, and the unwanted pieces are iron or steel that a magnet can attract.

Do Not Use It as a Mineral Disc Separator

If the job is to recover weakly magnetic minerals or to run a wet mineral-separation stage, use the magnetic separator designed for that process instead.

Working Principle

How Does a Disc-Type Suspended Electromagnet Remove Tramp Iron?

When the electromagnet is energized, it pulls iron and steel pieces out of the material moving below it and holds them on the magnet face. With the documented manual-clean RCDB type, the line stops for a controlled cleaning step so the captured metal can be removed safely.

1

Material Passes Below

Material moves below the magnet at the actual belt speed and material depth.

2

Iron Enters the Working Zone

Iron and steel pieces are pulled toward the magnet. Distance, gravity and the surrounding material make them harder to lift.

3

Iron Is Lifted and Held

Iron that is pulled free from the material is held on the magnet face.

4

Planned Manual Cleaning

Accumulated iron is removed during a controlled stop after safe isolation according to the final design and site procedure.

How to Read This Table

  1. Start with belt width to find the first RCDB model.
  2. Check the maximum material depth, not only the normal depth.
  3. Check the hardest iron target you actually need to remove.
  4. Check the real working distance from the magnet face to that target.
  5. Keep the model only if all of these conditions fit. If they do not, move to a larger model or another separator type.

What “Continuous” means: this is the operating-mode wording in the published technical specifications. It does not mean the separator automatically removes captured iron. The RCDB family on this page is manual-clean. What A×B×C means: these dimensions are copied from the published technical specifications. Do not use them for support steel or clearance planning until the selected-model drawing defines A, B and C.

Example: for a 1,000 mm belt, start with RCDB-10 because that is the documented family reference. Keep RCDB-10 only if the real target distance, material depth, belt speed and installation all fit. If they do not, change the model or choose another separator instead of forcing the belt-width match.

What the mT value tells you: the listed mT figure is a magnetic flux density value from the family data. The source does not define the exact measurement point, probe direction or test method. Do not treat it as pull force or separation efficiency. We still check the target iron, material depth, real target distance, belt speed and conveyor condition before confirming a model.
What Changes Capture Performance

What Determines Whether Tramp Iron Is Actually Captured?

Tramp-iron capture depends mainly on the real distance from the magnet to the iron, material depth, belt speed, target size and shape, and where the magnet is installed. A surface Gauss or mT value alone cannot predict separation performance.

What Is the Working Distance?

Working distance is the real distance from the magnet face to the iron you need to remove. It includes the air gap above the material plus the depth of the target inside the material layer. If the target is buried deeper, the magnet must reach farther. This is why material depth can change the model even when belt width stays the same.

Does a Higher Gauss Number Mean Better Separation?

No. Gauss and mT describe magnetic flux density at a defined measurement point. They do not directly tell you pull force, working distance, separation efficiency, throughput or recovery rate. We use the magnetic value together with target iron, working distance, belt speed and material depth.

Material Depth

Send both normal and maximum material depth. A deeper material layer increases the distance between the magnet and buried iron. If the maximum depth pushes the target too far from the magnet, we move to a larger model or change the installation.

The Iron You Need to Remove

A large exposed steel plate is easier to attract than a small bolt buried deep in the material. We select against the harder important target, not the easiest piece.

Belt Speed

Higher belt speed gives the magnet less time to attract the iron. Use the real operating speed. If the conveyor runs at several speeds, send the highest relevant speed.

How the Material Sits on the Belt

Lumpy, dense, wet, sticky or uneven material can make iron harder to pull free. Tell us the real feed condition, not only the material name.

Where the Magnet Is Installed

Nearby steel, trough shape, headroom and support position can change the workable magnet location. We check the installation drawing before confirming the model.

What a Magnetic Reading Does Not Tell You

A magnetic reading does not by itself tell you pull force, maximum working distance, separation efficiency, throughput, recovery rate or whether a buried target will be captured.

Model Selection Logic

How We Choose the Starting RCDB Model

We follow four steps. First, we choose the right type of separator. Next, belt width gives the first RCDB model to check. Then we check the hardest iron target. Finally, we make sure the model fits the real installation.

1

Choose the Right Separator Type

Occasional iron + planned cleaning stop → manual-clean RCDB. Frequent iron or automatic discharge → self-cleaning suspended separator. Aluminum, copper, wet slurry or mineral recovery → another separator type.

2

Start With Belt Width

Use actual belt width to identify the documented RCDB family starting model. Do not treat this as the final selection.

3

Check the Hardest Iron to Remove

Use the maximum relevant material depth, the real distance from the magnet face to the iron, the highest relevant belt speed, and the iron piece that matters most.

4

Confirm the Model or Choose Another One

If the starting model can reach the hardest iron target and fits the installation space, keep it for quotation. If it cannot, move to another model or choose a different separator type or installation.

1,000 mm belt example: start with RCDB-10 because it is the documented family reference for a 1,000 mm belt. Do not confirm RCDB-10 from belt width alone. Check the real target distance, normal and maximum material depth, belt speed, target iron and layout. If a critical condition does not fit, change the model or choose another separator before quotation.

What We Check Before We Confirm the Separator

We do not confirm the separator from one number. We check the conveyor, material depth, target iron, installation and electrical requirements together. If one of these changes the job, we change the model or separator type.

Keep the check matched to the question. A product photo shows the product. The RCDB table gives a starting model. A drawing confirms dimensions and installation points. A magnetic reading shows the field at the stated point. If the order needs to show that a defined iron piece is captured, use an agreed iron-piece test under the agreed conveyor condition.
Suitable / Not Suitable

When We Recommend This Configuration — and When We Do Not

We Recommend the Manual-Clean RCDB When

  • The material is dry and moves on a belt conveyor.
  • The unwanted contaminant is ferromagnetic iron or steel.
  • Tramp iron is occasional enough that a planned cleaning stop is practical.
  • The magnet can be positioned close enough to the hardest target for the selected model.
  • The support structure can safely carry the separator and provide service access.
  • The plant can isolate the equipment safely before manual cleaning.

We Recommend Another Separator When

  • Frequent tramp iron or no-stop production: choose a self-cleaning suspended / cross-belt separator.
  • No continuous electrical excitation preferred: evaluate a suspended permanent magnet if its magnetic duty can meet the working distance.
  • Aluminum, copper or other non-ferrous target: use the appropriate non-ferrous separation technology.
  • Wet or slurry process: use a wet magnetic separator.
  • Weakly magnetic mineral recovery: use a mineral-processing magnetic separator.
  • Unsafe support, no cleaning access or too much distance to the target: change the installation or choose another separator before ordering.
Installation, Cleaning & Controls

How Should the Magnet Be Installed and Controlled?

The magnet and its installation must work together. A correct model can still perform poorly if it is installed too far from the material or in the wrong position. Send us the real separation point, magnet-face-to-belt distance, normal and maximum material depth, support position, headroom, nearby steel, cleaning access and site electrical requirement.

A photographed Corvelan configuration with a separate control cabinet. We confirm the power supply, control method, enclosure and any certification requirement for the quoted project.
IF: the magnet is above a normal conveyor section
THEN: send belt width, belt speed, magnet-face-to-belt distance, normal/maximum material depth and headroom.

We use those values to establish the real target distance and check the RCDB starting model.

IF: the magnet is near a head pulley, transfer point or unusual trajectory
THEN: send the layout drawing or a clear side-view photo before we confirm the model.

How the material moves, where the iron sits, nearby steel and service space can differ from a straight conveyor section.

IF: only local start/stop control is required
THEN: state the available voltage/frequency and local control requirement.

We choose the electrical arrangement from that requirement. We do not assume the control cabinet shown in the photo applies to every order.

IF: the separator must interlock with the conveyor or plant PLC
THEN: send the required start/stop logic, status feedback and remote I/O requirement before quotation.

Tell us which start/stop, status or alarm signals you need. We include those PLC input/output (I/O) requirements in the quotation.

IF: the site is a classified hazardous area
THEN: do not assume a standard enclosure is acceptable.

Send the required zone or class, whether the hazard is gas or dust, and the standard your project follows. We only describe the separator as suitable for that hazardous area when the quoted documents support it.

IF: manual cleaning cannot be performed with safe isolation and access
THEN: do not use the manual-clean RCDB as specified.

Choose a self-cleaning separator or change the installation so captured metal can be removed safely under the site procedure.

Send the actual distances: do not send only “the magnet will be 300 mm above the material.” Send the magnet-face-to-belt distance plus normal and maximum material depth. This lets us calculate the real distance to iron buried near the belt.
How We Check the Final Selection

How Should the Final Separator Be Checked?

Use the check that matches the result you actually need. If you need a magnetic-field value, measure the field at a defined point. If you need to know whether a critical iron piece can be removed, run that piece or a representative piece through the conveyor. If you need to confirm the installed unit, run the agreed function check.

What you need to knowHow to check itAgree these details first
Magnetic flux density at a stated positionMagnetic measurementInstrument, probe direction, measurement point, gap, energized condition and target value.
Whether a known iron piece can be capturedRun the actual or representative iron piece through the conveyorTarget size, shape and mass; target position; belt speed; material depth; real target distance; number of passes; and the pass/fail rule.
Whether the installed separator and controls work correctlyInstalled function checkApproved layout, mounting position, clearances, electrical supply, control response, safe access and cleaning procedure.
A specified removal percentage or recovery resultProject-specific performance testFeed condition, contaminant population, sampling method, test duration, pass/fail metric and who records the result. Do not use surface Gauss as a substitute.
The test must match the result. A Gauss or mT reading shows only the magnetic field at the stated point. It does not by itself show pull force, capture rate or separation efficiency.
Examples That Show How the Choice Changes

How Does the Separator Choice Change With the Process?

The examples below show how we would apply the selection rules. They are not customer project records and they are not published test results. Replace the example values with the actual project data before quotation.

Example A

Occasional Iron on a 1,000 mm Conveyor

Use a manual-clean RCDB suspended electromagnet.
MaterialCrushed limestoneBelt width1,000 mmBelt speed1.6 m/sMaterial depth120 mm normal / 160 mm maximumTargetBolts, nuts and occasional steel piecesIron frequencyOccasionalCleaning stopAvailable

Why: iron appears only from time to time, so continuous automatic discharge is not required. The 1,000 mm belt points first to RCDB-10 in the RCDB family table.

What we still checkReal magnet-to-target distance, target size, belt speed, maximum material depth, installation space and the selected-model drawing.
How we would check the selectionRun the agreed bolt or steel piece at the real belt speed and maximum relevant material depth. Put the target at the hardest agreed position and define the pass/fail rule before the test.
When we change the choice: if iron becomes frequent or the conveyor can no longer stop for cleaning, move to a self-cleaning suspended electromagnet.
Example B

Frequent Iron and No Routine Cleaning Stop

Do not use the manual-clean RCDB as the first choice.
MaterialRecycled aggregateBelt width1,200 mmBelt speed2.0 m/sMaterial depth180–220 mmTargetBolts, rods and larger steel piecesIron frequencyFrequentCleaning stopNot acceptable

Use: a self-cleaning suspended electromagnet or cross-belt electromagnetic separator. Captured metal must be carried away without repeated production stops.

What we still checkConveyor width, material depth, largest expected piece, discharge-side clearance, magnet position and the required discharge direction.
How we would check the selectionRun representative iron pieces and confirm that they are captured and then carried clear by the discharge belt without blocking the discharge path.
When we change the choice: if iron becomes occasional and planned cleaning stops become practical, the manual-clean RCDB can be reviewed again.
Example C

1,000 mm Belt, but the Material Is Too Deep for the First Model

Do not keep RCDB-10 just because the belt is 1,000 mm.
Belt width1,000 mmMaximum material depth280 mmFirst model from belt widthRCDB-10RCDB-10 family material-depth reference≤250 mmNext family model to checkRCDB-12RCDB-12 family material-depth reference≤300 mm

Use: RCDB-12 as the next family model to check. The deeper material moves the hardest target farther from the magnet, so belt width alone is not enough to keep RCDB-10.

What we still checkMaximum depth measurement, belt profile, magnet-face-to-belt distance, target size and shape, headroom, support arrangement and the selected-model drawing.
How we would check the selectionUse the agreed iron-piece test at the maximum relevant material depth and real belt speed. If the target does not pass, change the magnetic duty or change the installation.
Important: RCDB-12 is still the next model to check, not an automatic final model.
Example D

Aluminum and Copper Are the Main Targets

Do not use the RCDB suspended electromagnet for this job.
MaterialMixed recycled materialMain targetsAluminum and copperFerrous steelAlready removed upstream

Use: an eddy current separator or another system designed for non-ferrous metal recovery. RCDB electromagnets are designed to attract iron and steel, not aluminum or copper.

What we still checkTarget metals, particle size, feed condition, material flow and the required non-ferrous separation result.
Why the RCDB is wrong hereThe main targets are non-ferrous. A stronger RCDB does not change the separation principle.
About these examples: they explain how the selection changes when the process changes. They are not customer projects, test reports or performance promises.

FAQ

Disc-Type Suspended Electromagnetic Separator FAQ

What does “disc-type” mean on this page?

It means the round RCDB-style suspended electromagnet installed above a conveyor for ferrous tramp-metal removal. It does not mean the multi-disc mineral-processing separator used for weakly magnetic mineral beneficiation.

When should I choose the manual-clean RCDB disc type?

Choose the manual-clean RCDB when the material is dry and moves on a conveyor. The target should be iron or steel that a magnet can attract. This option fits best when tramp iron appears only from time to time and the line can stop for cleaning. If iron appears often or the line cannot stop, choose a self-cleaning suspended separator instead.

When should I choose a self-cleaning separator?

Choose a self-cleaning suspended or cross-belt electromagnetic separator when tramp iron is frequent, automatic discharge is required or repeated manual-cleaning stops would interfere with production.

Can I select the separator only from throughput?

No. The same throughput can create different material depths depending on belt width, belt speed, bulk density and feed distribution. Use throughput together with belt width, actual belt speed, normal and maximum material depth and the target iron.

Which RCDB model fits a 1,000 mm conveyor?

Start with RCDB-10 because it is the documented family reference for a 1,000 mm belt. Keep RCDB-10 only after checking the real distance from the magnet to the iron, normal and maximum material depth, belt speed, target iron and installation. If those conditions do not fit, change the model or choose another separator.

How high should the electromagnet hang above the conveyor?

Do not use one hanging height for every job. Send the magnet-face-to-belt distance plus normal and maximum material depth. We check the real distance to the hardest iron target, because iron buried near the belt is farther from the magnet than iron near the top of the material.

Does “continuous” in the family table mean automatic iron discharge?

No. “Continuous” is the operating-mode wording in the source family data. It does not mean the manual-clean RCDB automatically removes captured iron. If you need automatic discharge, choose a self-cleaning suspended separator.

Does a higher Gauss or mT value guarantee better iron removal?

No. Gauss and millitesla describe magnetic flux density at a defined measurement point. They are not pull force and they are not separation efficiency. Capture also depends on working distance, target size and shape, material depth, belt speed and material condition.

Do I need a separate electrical control cabinet?

Some photographed Corvelan configurations use a separate control cabinet. Tell us the site voltage and frequency, whether you need local or remote control, any PLC interlock or I/O signals, and the installation environment. We use those details to define the electrical arrangement for the quotation.

How should the final separator be checked?

If you need a magnetic-field value, measure it at a stated point. If you need confirmation that a critical iron piece can be removed, run that piece or a representative piece through the conveyor. If you need to confirm the installed unit, use a functional check. If you need a removal percentage, agree a full performance test before the test starts; do not use surface Gauss as the acceptance result.

What should I send Corvelan for selection and quotation?

Send the material, target iron, throughput or conveyor loading, belt width, belt speed, normal and maximum material depth, magnet-face-to-belt distance, available headroom, site power and a photo or drawing of the proposed installation point. Add acceptance criteria, hazardous-area classification or plant control requirements when they apply.

What does Corvelan check before confirming a separator?

We use different information for different questions. Product photos confirm the physical product. The RCDB family table gives a starting model. The selected-model drawing confirms installation details. A magnetic measurement shows only the stated field value. Use an agreed iron-piece test when the order needs to confirm that a defined iron piece can be captured under the stated condition.

Are the A/B/C/D examples on this page real customer projects?

No. They are selection examples created to show how the choice changes when the process changes. They are not customer projects, test reports or performance results. A real project must use its actual conveyor, material, target, installation and acceptance data.
