Corvelan supplies RCYB suspended permanent magnet separators for conveyor lines. They remove unwanted iron and steel from material moving on the belt. This unwanted metal is often called ferrous tramp iron. We choose the model from your conveyor and material details. We check belt width, material depth, the real distance from the magnet to the iron, belt speed, target iron and installation space. We do not choose a model from one surface magnetic reading alone.
Send us your belt width, the normal and maximum material depth, and a conveyor photo. We can then narrow the RCYB model range quickly.

The RCYB is a permanent magnet installed above a conveyor. It attracts unwanted iron and steel and holds them on the magnet face. This helps keep the metal away from crushers, screens and other equipment farther down the line. The permanent magnetic circuit does not need excitation power. The RCYB shown here is a manual-clean model, so captured metal stays on the magnet until the line is safely stopped and cleaned.
This page focuses on the manual-clean suspended permanent magnet shown in the product and installation photos. You may also see the term overband magnet when searching for this type of equipment. In many catalogs, that name is used for a self-cleaning magnet with a discharge belt. If you need continuous automatic iron discharge, we can supply a self-cleaning cross-belt separator instead.
Start with your conveyor belt width. Then check the material depth, suspension height, belt speed and the iron you need to remove. We use these details to confirm the final model. The table below shows the current RCYB series reference data used on this page.
These models cover the widest belt-width and suspension-height range in the supplied RCYB data.

*mT means millitesla, a unit used to measure magnetic field strength. The values above come from the supplied RCYB series sheet. If magnetic field strength must be checked for your order, we will define the test method. The quotation, drawing or test document will state where and how the reading is taken. A Gauss or mT reading at one point does not by itself prove pull force or separation efficiency.
Corvelan starts with your belt width, but we do not choose the magnet from belt width alone. We also check how deep the iron is buried and how far it is from the magnet. Then we check belt speed, installation space and how the unit will be cleaned.
We use your belt width to narrow the RCYB model range and the required magnet size.
We check the normal and maximum depth of material on the belt. Engineers often call this burden depth. We also check the real distance from the magnet face to the iron inside the material, not only to the top of the material.
The faster the belt runs, the less time the iron spends under the magnetic field. We check belt speed when choosing the model and installation height.
Tell us the size, shape and approximate amount of iron or steel you need to remove. These details affect how hard the separation job is.
We check the available headroom, support steel, conveyor shape and nearby steelwork before we confirm where the magnet will hang.
We check how often iron may build up on the magnet. If planned manual cleaning would stop the line too often, we can use a self-cleaning overband instead.
We use suspended magnets above conveyors that may carry unwanted iron or steel with the material. The magnet removes this metal before it can damage equipment or move into the next process.
Remove unwanted iron carried with ore, stone and aggregate before it reaches crushers, screens or transfer equipment.
Remove unwanted iron before it reaches crushers, mills or other equipment in the cement line.
Remove unwanted iron and steel from coal moving on the conveyor.
Remove unwanted iron before selected downstream processing steps without touching the material stream.
Use a suspended magnet above suitable dry bulk materials when the process conditions match the quoted equipment.
Remove unwanted iron and steel from suitable raw materials moving on a conveyor.
Keep unwanted steel pieces away from suitable handling, shredding and size-reduction equipment.
Use the separator above suitable dry bulk material conveyors. The unwanted metal should be iron or steel that is strongly attracted by a magnet.
Material moves under the suspended magnet on the conveyor. Iron and steel that are strongly attracted by a magnet move upward toward the magnet face. Engineers call these ferromagnetic materials. The deeper the iron is buried in the material, the harder it is to pull out. This is why the real distance from the magnet to the iron matters more than one surface magnetic reading by itself.
With the manual-clean RCYB, captured metal stays on the magnet face until the conveyor is stopped and the area is made safe for cleaning. The permanent magnetic field is always active, even when nearby electrical equipment is switched off.

The magnet must be close enough to the iron to do its job. It also needs safe space for the material, support frame and cleaning work. Send us a conveyor photo or drawing and we will check the proposed position before we confirm the installation.

This works when the magnet can hang close enough to the iron. It must still leave enough clearance for the material and the largest piece that may be captured.
A transfer point can expose the material more openly. We still check where the material falls, where the magnet can be supported and whether there is enough safe access for cleaning. There is no single installation angle that fits every conveyor.
Measure from the magnet face to the iron inside the material. Do not measure only to the top of the material. Iron buried deeper is harder to remove.
Material depth affects how easily the magnet can reach the iron. Large lumps, moisture, density and tightly packed material can also make the iron harder to pull out.
Large flat steel, compact pieces, long bars and small irregular fragments do not respond in exactly the same way. Tell us what you need to remove so we can check the duty.
Higher speed reduces exposure time and can make the capture window more demanding.
The conveyor shape, support steel, headroom and nearby steelwork all affect the installation. They can limit how close the magnet can be and how it is supported.
Captured iron must be removed before too much metal builds up on the magnet face. Heavy buildup can reduce safe clearance and disturb normal operation.
The main difference is how captured iron is removed. Choose the RCYB manual-clean magnet when planned cleaning stops are acceptable. Choose a self-cleaning overband when you need automatic iron discharge or manual cleaning would stop production too often.
The terms “overband magnet” and “cross-belt magnet” are often used for self-cleaning suspended units. We keep that product separate from the manual-clean RCYB shown here so the quoted machine matches the way your line needs to work.
Send us your belt width, normal and maximum material depth, and belt speed. Also send the iron you need to remove and one clear conveyor photo. We will narrow the RCYB model range and tell you what else we need for a quote.
The permanent magnetic field is always active. Safe cleaning and maintenance must control both conveyor hazards and magnetic hazards. Switching off nearby drives does not switch off the magnet.

Tell us which inspection records you need before we quote. We can then confirm the inspection items and documents that will be included for the selected order. If your order requires factory inspection records or a performance test, tell us before quotation so we can agree on the inspection scope and test method.
If dimensional inspection is required, define the dimensions that must be checked against the approved drawing. Typical items include overall size and suspension-point spacing.
If an mT or Gauss reading is required, define the instrument, measurement point, probe direction and distance first. A reading without these details is hard to compare.
Define any required checks for the housing, lifting points, product identification and packing. We confirm the agreed inspection scope in the quotation or order documents.
The real installation photo shows the product in its working position above a conveyor. It helps confirm the type of installation, available headroom, support structure and access that must be considered before the magnet is selected.
For your project, we record the selected model, installation conditions and any agreed inspection or test results.

Before we confirm performance, we agree on what the separator needs to remove. We also define how the result will be checked. We may define the iron size, material condition, material depth and belt speed. We can also define the distance to the iron, the number of test passes and the pass/fail rule. If magnetic field strength is part of the test, we also define the instrument, probe direction, measurement point and distance.
Capture performance depends on the target metal, material depth and installation height. If you need a measurable removal target, we can agree on a representative test method before ordering.
We choose the magnet around your actual conveyor, not from belt width alone. Send us the conveyor size, material depth, belt speed, target iron and installation photo. We use these details to match the model and check where it will be installed. We also define the drawing or inspection items that matter for the order.
We use your belt width to identify the RCYB starting range. Then we check material depth and the real distance from the magnet face to the iron.
We check the proposed position, support space, lifting access, nearby steelwork and cleaning clearance from your photo or drawing.
We confirm the selected model and key dimensions in the quotation or drawing. If you need inspection records or a defined performance check, tell us before the order so the required method can be agreed.

It is a permanent magnet installed above a conveyor to remove unwanted iron and steel from moving bulk material. The manual-clean RCYB holds the captured metal on the magnet face until the line is safely stopped and cleaned.
Not always. Many suppliers use “overband magnet” for a suspended magnet fitted with a moving self-cleaning belt. This page focuses on the manual-clean RCYB suspended permanent magnet. If you need automatic iron discharge, Corvelan can supply a self-cleaning cross-belt separator instead.
The standard RCYB table on this page covers reference belt widths from 400 to 1600 mm. Belt width is only the starting point. We also check material depth, suspension height, belt speed, target iron and the available installation space.
No. The permanent magnetic circuit does not need electrical excitation power. The RCYB shown here is manual-clean, so it does not use a self-cleaning belt drive.
Use the selected model’s rated suspension height as a starting reference. Then check the real distance from the magnet face to the iron inside the material. Material depth, clearance and the largest captured piece also affect the final installation height.
No. A higher magnetic reading at one point does not automatically mean the separator will remove more iron. Gauss or mT measures magnetic field strength at a defined point. Pull force, real working distance, iron size and shape, material depth and belt speed also affect the result.
No, not as the main separation method. A suspended permanent magnet is made mainly for iron and steel that are strongly attracted by a magnet. Aluminum, copper and other non-ferrous metals normally need another separation technology.
Send us the material, the iron or steel you need to remove, and your belt width. Also send the normal and maximum material depth, belt speed if known, and a conveyor photo or drawing. If you have them, also send throughput, particle size, moisture, headroom and any test or documentation requirements.
You do not need a complete engineering drawing to get started. Send us the conveyor details that affect model fit and the real distance from the magnet to the iron. We will tell you what else we need before we quote.
Send us your belt width, material depth, belt speed, the iron you need to remove and a conveyor photo. We will use the RCYB reference range to choose a starting model. Then we check the real working distance and confirm whether the manual-clean suspended magnet fits your line.
