Industrial Magnetic Separation

Magnetic Separation Equipment

We supply magnetic separation equipment for removing tramp iron, cleaning dry powders, separating magnetic minerals and handling wet magnetic separation. If you are not sure which type you need, start with your material, how it moves, and what you want to remove.

Conveyors Dry Bulk Fine Powder Wet Slurry Pipeline
What material are you processing?

Coal, ore, aggregate, powder, slurry or another bulk material?

What do you want to remove or recover?

Large iron, steel pieces, fine ferrous contamination or a magnetic mineral?

How is the material moving?

On a belt, through a pipe, as dry bulk, or as slurry? Material depth, speed and installation distance can change the final choice.

What Are You Trying to Do?

Start with the job you need the equipment to do. The same material can need a different separator when the goal changes.

Protect a crusher, mill or other equipment

Remove large tramp iron before it reaches downstream machinery.

Clean the product

Remove unwanted magnetic contamination from the material before the next process or final use.

Recover magnetic material

Separate a useful magnetic fraction from the feed instead of treating it only as contamination.

Detect metal

Use metal detection when finding metal matters more than removing it with a magnetic field.

What Type of Magnetic Separator Do You Need?

Now look at how the material moves. This usually narrows the equipment type quickly.

Material moves on a belt

Start with a suspended magnetic separator when the main job is removing tramp iron from above the belt.

Choose another type if you need the full material stream split into magnetic and non-magnetic parts.

You can replace the head pulley

A magnetic pulley can separate magnetic material at the conveyor discharge point.

Use a suspended magnet instead if the head pulley cannot be changed.

Dry bulk needs continuous separation

Use a magnetic drum when the full material flow needs to pass through a continuous magnetic separation zone.

Fine dry powder

Use a high-intensity magnetic filter when small magnetic or ferrous contamination must be removed from dry powder.

Weakly magnetic dry particles

Use a magnetic roller when the dry feed contains weakly magnetic particles and can be fed in a controlled layer.

Slurry or pulp

Use a wet magnetic separator. Do not choose a dry drum just because the mineral itself is magnetic.

Dry material moves through a pipe or chute

Use a pipeline magnetic separator for inline iron removal.

You need to find metal

Use a metal detector. A detector and a magnetic separator do different jobs.

Choose Your Magnetic Separator Type

Select a product type below. Each group shows when it fits, when another type may be better, and what you should check before choosing.

Suspended Permanent Magnetic Separators

Use these separators above a conveyor when you need to remove iron or steel from moving bulk material.

Good choice when

Your material moves on a belt and a permanent magnetic system can reach the target metal.

Choose another type when

Choose another type if you need a full-stream magnetic split or the target is weakly magnetic fine material.

What to check first

Material depth, real distance to the buried metal, belt speed and how often iron appears.

Suspended Electromagnetic Separators

Use these separators above a conveyor when your application needs an electrically powered magnet.

Good choice when

You need a suspended conveyor magnet and an electromagnetic system fits the required size and working distance.

Choose another type when

Choose another type if the job is full-stream mineral separation rather than tramp-iron removal above a belt.

What to check first

Belt width, material depth, working distance, iron size, cleaning method, power supply and available space.

Magnetic Drums & Magnetic Pulleys

Use a magnetic pulley at the conveyor head. Use a magnetic drum when the full material flow needs continuous separation.

Good choice when

You can present the material directly to the magnetic pulley or drum and separate magnetic from non-magnetic material continuously.

Choose another type when

Choose a suspended separator if you only need to lift tramp iron from above a moving belt.

What to check first

Feed size, how the material reaches the magnetic surface, speed and where each material stream will discharge.

Dry High-Intensity & Magnetic Roller Separators

Use these types for fine dry contamination or weakly magnetic dry particles, not for large tramp iron on a conveyor.

Good choice when

The material is dry and either very fine or only weakly magnetic.

Choose another type when

Choose a suspended conveyor magnet if the main problem is large iron or steel pieces on a belt.

What to check first

Particle size, how strongly the target responds to a magnet, moisture and how evenly the material can be fed.

Wet Magnetic Separators

Use wet magnetic separators when the material is handled as slurry or pulp.

Good choice when

The separation happens in a true wet process and the target material responds to a magnetic field.

Choose another type when

Do not choose wet equipment just because dry bulk is damp or slightly sticky.

What to check first

Slurry condition, particle size, whether the target is strongly or weakly magnetic, and how the material flows through the separator.

Pipeline Magnetic Separator

Use this type when dry or gravity-fed bulk material moves through a pipe or chute and iron needs to be removed inside the flow.

Good choice when

Dry bulk passes through a pipe or chute and you need inline iron removal.

Choose another type when

Choose wet equipment if the line carries a true liquid or pumped slurry.

What to check first

Pipe or chute size, material flow, access for cleaning and the size of the metal you want to remove.

Related Metal Detection Equipment

A metal detector finds metal. A magnetic separator captures or separates magnetic material. They solve different problems.

Good choice when

You need to detect metal on a conveyor rather than remove it with a magnetic field.

Choose another type when

Choose magnetic separation first when the main job is to capture iron or steel from the material stream.

What to check first

Which metals matter, where the detector will sit, material conditions and what should happen after metal is detected.

Which Option Should You Choose?

Permanent Magnet or Electromagnet?

Choose a permanent magnet when it can reach the target metal at your real installation distance and you want a magnetic field without electrical excitation.

Choose an electromagnet when your application needs an electrically powered magnetic system.

Important: a deeper material bed or longer distance can make either option harder. Do not choose from magnet type alone.

Manual Clean or Self-Cleaning?

Iron appears only occasionally: manual cleaning can be the simpler choice when access is safe.

Iron appears often: use self-cleaning when you want the captured metal removed automatically.

But check the space: self-cleaning still needs enough room for the metal to discharge.

Suspended Magnet, Magnetic Pulley or Drum?

Above a belt: suspended separator.

At the conveyor head: magnetic pulley.

Full dry material stream: magnetic drum.

A magnetic pulley is not just a suspended magnet placed at the conveyor head. The material passes around the magnetic pulley itself.

What Affects Magnetic Separation Results?

The same separator can give different results when metal size, distance, material depth, speed or material condition changes.

What are you trying to remove?

Large tramp iron, small steel pieces, fine ferrous contamination and weakly magnetic minerals do not behave the same way.

How far is the metal from the magnet?

This is the working distance. A longer distance makes capture harder. Measure to the hardest-to-reach metal, not only to the top of the material.

How deep is the material on the belt?

This is often called burden depth. A deeper bed can place buried metal much farther from the magnet.

How fast is the material moving?

A faster belt gives the magnet less time to attract, lift and move the metal away from the product stream.

Is the material dry, damp, sticky or in slurry?

Moisture, lumps and poor flow can change how the material reaches the magnetic area. True slurry needs a wet separation method.

How will the captured metal leave?

If iron appears often, automatic cleaning may help. You still need enough space for the removed metal to discharge without blocking the line.

When Several Conditions Change at the Same Time

This is where many wrong choices happen. One condition may point toward a separator, but another condition can change the answer.

Deep Material + Fast Belt

A deep bed puts buried metal farther from the magnet. A fast belt gives the magnet less time to capture it. When both happen together, the job is harder than either condition alone.

Send us: material depth, belt speed and the real distance to buried metal.

Frequent Iron + Limited Discharge Space

Frequent iron usually points toward self-cleaning. But automatic cleaning still needs room for the captured metal to leave the belt.

Check: discharge direction, side space and the size of the largest iron piece.

Fine Material + Weak Magnetic Response

Fine material does not automatically mean a magnetic filter is the right choice. If the particles are also weakly magnetic, a roller or another high-intensity type may fit better.

Check: particle size, magnetic response and how evenly the material can be fed.

Why the Same Magnetic Separator Can Give Different Results

Conveyor A

  • Shallow material bed
  • Slower belt
  • Large iron pieces

Result: this is usually an easier capture condition.

Conveyor B

  • Deep material bed
  • Faster belt
  • Smaller iron pieces

Result: this is a harder capture condition even if the belt width is the same.

What this means

Same belt width does not mean the same separator will give the same result. Material depth, speed, target size and distance can all change the equipment you need.

Gauss, Pull Force and Actual Separation

A higher Gauss number does not automatically mean better separation. Compare magnetic numbers only when the measurement method and application are similar.

High Gauss + Long Distance

A high surface reading does not prove the magnet can still capture metal far away or deep inside the material.

High Gauss + Fast Belt

The magnetic field may be strong, but the target still has less time to respond when the belt moves faster.

High Gauss + Wrong Equipment Type

A strong conveyor magnet is not a direct replacement for a roller or other high-intensity separator when the target is weakly magnetic fine material.

Dry, Damp or Slurry?

Wet material is not always a wet magnetic-separation application. The key question is how the material actually flows through your process.

Dry or Slightly Damp Bulk Material

Dry equipment may still be suitable if the material continues to move as normal bulk solids.

Sticky or Clumped Material

Moisture can cause poor feeding, buildup or uneven layers. In this case, material flow may be the first problem to solve.

True Slurry or Pulp

Use a wet magnetic separator when the material is carried in a liquid process and separation happens in that wet flow.

Magnetic Separator Comparison

Your Application Good Choice What Can Change the Choice What to Tell Us
Iron above a conveyor Suspended permanent or electromagnetic separator Deep material, high speed, frequent iron, limited discharge space Belt width, material depth, belt speed, metal size, working distance
Frequent tramp iron Self-cleaning suspended separator Very limited side space or difficult discharge direction How often iron appears, largest piece, available discharge space
Conveyor head can be replaced Magnetic pulley Head pulley cannot be changed or discharge paths cannot be separated Pulley size, belt layout, discharge arrangement
Dry bulk needs continuous separation Dry magnetic drum Moisture, particle size, poor feed spread or true slurry conditions Particle size, feed condition, magnetic material, feed rate
Fine dry powder High-intensity magnetic filter Weak magnetic response may point to another high-intensity type Powder type, particle size, target material, cleaning preference
Weakly magnetic dry particles Magnetic roller Very uneven or poorly controlled feed Particle size, material type, how the feed is spread
Strongly magnetic material in slurry Wet drum magnetic separator Weak magnetic response may move the choice toward wet high-intensity Slurry condition, particle size, target magnetic material
Dry material through pipe or chute Pipeline magnetic separator The line carries a pumped slurry or true liquid process Pipe/chute size, material condition, access for cleaning
Aluminum, copper or brass Use another separation method Conventional magnetic separation is not the first choice Metal type, size and where it appears in the process

Where Should the Magnetic Separator Be Installed?

Above the Conveyor

Use a suspended or cross-belt separator. Keep enough space for the magnet, supports, cleaning and metal discharge.

Watch out: raising the magnet only to gain more clearance can also increase the working distance and make capture harder.

At the Conveyor Head

Use a magnetic pulley when the head pulley can be changed and the magnetic and non-magnetic material can follow different paths.

Inside a Dry Material Line

Use a drum, pipeline separator, filter or roller depending on how the material moves and what you need to remove.

In a Wet Process

Use wet magnetic separation when the material is handled as slurry or pulp. Tell us whether the target is strongly or weakly magnetic.

Already Using a Magnetic Separator but Not Getting the Result You Need?

Metal is still passing under the separator

Check the metal type, material depth, real working distance and belt speed first. These conditions can change the result even when the separator itself has not changed.

It catches metal near the surface but misses buried pieces

Check burden depth and the real distance from the magnet to the buried metal. Surface metal may be close enough to capture while deeper pieces are not.

It works at low speed but misses metal at normal production speed

Check the belt speed. Faster movement gives the magnet less time to attract and move the target metal.

The self-cleaning separator captures iron but discharge is poor

Check discharge direction, side space, the size of the iron pieces and whether material buildup is blocking the discharge area.

Fine contamination is still passing through

Do not assume you only need a stronger suspended magnet. Fine contamination may need a magnetic filter, roller or another high-intensity separator depending on particle size and magnetic response.

What Should You Send Us?

You do not need every detail before contacting us. Start with your material, what you want to remove, and how the material moves. Then open the section that matches your equipment type.

For a conveyor magnet

Send belt width, belt speed, material depth on the belt, distance from the magnet to the material, metal size, how often the metal appears, and any available drawing or site photo.

For a magnetic drum or roller

Send the material, particle size, moisture, how much material you process per hour, the magnetic material you want to separate, and how evenly the feed can be spread.

For wet magnetic separation

Send the material, particle size, slurry condition, target magnetic material, how much material you process, and any information you have about the current wet process.

For a pipeline magnetic separator

Send the pipe or chute size, material type, how the material flows, access for cleaning, the metal size you want to remove, and a drawing or photo if available.

Why Work With Us?

We do not start with one model. Two projects with the same belt width can still need different equipment when material depth, speed, target-metal size or installation distance changes.

We help you choose the equipment type first, then check how it should fit your line. If you already have a drawing, site photo or existing separator, send it to us. We can use it to narrow the choice and confirm the main installation details before production.

We Start With Your Material

We first look at what you process and what metal or magnetic material you want to remove.

We Check the Conditions That Change the Choice

Material depth, speed, working distance, particle size and cleaning needs can all matter.

We Check How It Fits Your Line

Send us your belt size, available space, drawing or site photo.

We Confirm the Main Details Before Production

We confirm the main dimensions, cleaning method and installation details before the equipment moves forward.

Magnetic Separation Equipment FAQ

Which magnetic separator should I use for a belt conveyor?

For tramp iron on a belt conveyor, start with a suspended magnetic separator above the belt or a magnetic pulley at the conveyor head. If iron appears often, self-cleaning is usually the better choice. If it appears only occasionally and safe manual cleaning is easy, manual cleaning can be simpler.

Should I choose a permanent magnet or an electromagnet?

Choose a permanent magnet when it can reach the target metal at your actual installation distance and you want a magnetic field without electrical excitation. Choose an electromagnet when your application needs an electrically powered magnetic system. Belt width alone is not enough to make this choice.

When should I use a self-cleaning magnetic separator?

Use self-cleaning when iron appears often enough that manual cleaning would interrupt production. Also check that there is enough room for the captured metal to discharge. If iron is rare and safe manual cleaning is easy, a manual-clean separator can be simpler.

Dry drum or wet drum magnetic separator?

Use a dry drum for dry, flowable bulk material. Use a wet drum when the material is handled as slurry or pulp and the target material is strongly magnetic. Damp bulk material is not automatically a wet-separation application.

Does higher Gauss mean better separation?

No. Gauss tells you the magnetic field strength at the point where it was measured. It does not directly tell you pull force, working reach or separation efficiency. Deep material, long distance and high speed can still make capture difficult.

Can a magnetic separator remove all metals?

No. Conventional magnetic separators mainly work with materials that respond to a magnetic field. Iron and many steels can be removed magnetically. Aluminum, copper and brass need another separation method.

What is the difference between a magnetic drum and a magnetic pulley?

A magnetic pulley replaces the conveyor head pulley and separates material at the discharge point. A magnetic drum is a separate rotating magnetic unit used for continuous separation of a material stream.

Why does burden depth matter?

Burden depth means how deep the material is on the belt. A deeper bed can place buried metal farther from the magnet. That makes capture harder even when belt width stays the same.

Why does belt speed matter?

A faster belt gives the magnet less time to attract, lift and move the target metal. Deep burden and high speed together are harder than either condition alone.

Can the same separator work on two conveyors with the same width?

Not always. Two conveyors with the same width can have different material depth, speed, target-metal size and working distance. Those differences can change the separator you need.

What if my current magnetic separator misses iron?

First check the target metal, material depth, real working distance and belt speed. If it catches surface metal but misses buried pieces, distance and burden depth are often the first things to compare. Do not assume the answer is simply a higher Gauss number.

Magnetic separator or metal detector?

Use a magnetic separator when you need to capture or separate magnetic material. Use a metal detector when you need to find metal on the line. Some conveyor systems use both for different jobs.
