PRAB’s beltless magnetic slide conveyors transfer wet or dry ferrous chips, stamping slugs, fine grinding fines, and parts without carryover. PRAB magnetic conveyors use permanent ceramic magnets positioned beneath a non-moving stainless-steel slider bed to grip and move ferrous material with zero external moving parts. Because there is no belt to fail, jam, or contaminate, PRAB magnetic chip conveyors deliver continuous-duty performance in the most demanding CNC machining, stamping, and grinding environments.

Every PRAB magnetic slide conveyor is backed by the Performantee® Guarantee, engineered and assembled in the USA, and designed to integrate directly with chip processing systems and Guardian coolant recycling equipment downstream.

 


How PRAB Beltless Magnetic Conveyors Work

PRAB magnetic slide conveyors operate on a simple, proven mechanism:

  1. Permanent ceramic magnets (rare-earth magnets available) are mounted on a continuous chain running beneath a stationary stainless-steel slider bed.
  2. As the chain moves, the magnets drag ferrous material along the top surface of the slider bed toward the discharge end.
  3. At the discharge point, the chain curves away from the slider bed. The magnets leave the slider bed path and release the material cleanly, with no carryover.
  4. Because all moving parts are enclosed beneath the slider bed, there are no exposed chains, belts, or pinch points in the material-handling zone.

The magnetic field holds ferrous material firmly against the slider surface even on inclines, making PRAB magnetic conveyors suitable for elevation changes that would cause spillage on an open belt conveyor carrying fine chips or light stampings.


Low Maintenance, Long Life

Built for demanding environments, PRAB magnetic conveyors are low-maintenance with:

  • Self-lubricating oil reservoir for quiet, long-lasting operation
  • Permanent magnet cores with optional rare earth upgrades
  • Self-adjusting drive chain
  • Durable stainless-steel slider surfaces (smooth or Rigidized®)
  • Replaceable wear plates and robust construction for heavy use

Why Choose PRAB Magnetic Conveyors for Heavy-Duty Metalworking

  • Built for metalworking, not light-duty parts handling: PRAB magnetic conveyors are engineered specifically for the high-volume, wet, contaminated environments of CNC machining, stamping, and grinding. Competitor magnetic conveyors designed for light parts assembly or food handling are not built to the same wear standards.
  • Zero external moving parts: The beltless design eliminates the most common failure mode in chip conveyor systems: belt wear, belt jamming, and belt contamination with oily chips.
  • Performantee® Guarantee: Every PRAB magnetic conveyor is lab-tested and performance-verified before shipment. ROI is documented before you commit.
  • 20-30+ year service life: PRAB conveyors are engineered for decades of continuous-duty operation in harsh production environments. PRAB conveyors installed in 2004 are documented as still operational today.
  • Full integration with PRAB chip processing and coolant recovery: Chip processing systems, wringers, and Guardian coolant recycling systems connect downstream of PRAB magnetic conveyors to create a complete automated scrap and fluid management cell.

 

Magnetic Conveyor vs. Steel Belt Conveyor: When to Use Each

Use a PRAB magnetic slide conveyor when:

  • Scrap is ferrous only (steel, iron, or ferrous alloys)
  • Material is fine, light, or prone to spillage on belt conveyors (fine chips, grinding fines, thin stampings)
  • Zero carryover is required (clean machines, clean floors)
  • A low-maintenance, beltless design is preferred over a belted system

Use a PRAB steel belt conveyor when:

  • Scrap is mixed ferrous and non-ferrous, or non-ferrous only (aluminum, titanium, brass)
  • Scrap is heavy, bushy, or high-volume (stamping scrap, large turnings, die scrap)
  • Long runs or severe elevation changes require a heavy-duty belted design

Frequently Asked Questions About PRAB Magnetic Conveyors

Q: What is a beltless magnetic slide conveyor?

A: A beltless magnetic slide conveyor uses permanent magnets on a chain running beneath a stationary stainless-steel slider bed to move ferrous material. Because the slider bed does not move, there is no belt to wear, jam, or contaminate. PRAB’s beltless magnetic chip conveyors are designed for wet, oily metalworking environments where belt-type conveyors would require frequent maintenance.

 

Q: How do PRAB magnetic conveyors work?

A: Permanent ceramic magnets are mounted on a chain beneath a non-moving stainless-steel slider surface. As the chain moves, the magnetic field drags ferrous chips, stampings, or parts along the slider bed toward the discharge point. At discharge, the magnets separate from the slider bed path and release the material cleanly, with no carryover.

 

Q: What materials can PRAB magnetic conveyors handle?

A: PRAB magnetic conveyors handle ferrous materials only, including steel and iron chips, grinding swarf, stamping slugs, punch-outs, turnings, and small ferrous parts. For mixed-metal or non-ferrous scrap, a PRAB steel belt conveyor or oscillating conveyor is the appropriate choice.

 

Q: Can PRAB magnetic conveyors handle wet or oily chips?

A: Yes. PRAB beltless magnetic slide conveyors are specifically engineered for wet, oily, and contaminated metalworking scrap. The beltless design eliminates the belt contamination and slippage problems that reduce the performance of conventional belt conveyors in coolant-heavy environments.

 

Q: What is the difference between a magnetic conveyor and a steel belt conveyor?

A: Magnetic conveyors grip ferrous material through magnetic force, making them ideal for fine chips, light stampings, and applications where zero carryover is critical.

Metal Scrap Conveyor Examples:

PRAB’s engineering teams conduct scrap and coolant testing before specification, ensuring conveyors meet throughput and wear requirements. In one stamping plant, a PRAB pivot belt conveyor reduced carryover delays by 35% and improved scrap evacuation speed by 28%. This data-driven selection process extends belt life and minimizes energy use.

Resources:

Choosing the right conveyor depends on five variables: scrap form, fluid content, abrasiveness, volume, and layout.

  • Use a Steel Belt Conveyor for mixed, sharp, heavy, hot, or abrasive scrap, and when you need long-term durability.
  • Use a Pivot Belt Conveyor for thin-gauge, oily, or sticky stamping scrap that tends to cling to belts.
  • Use an Oscillating Conveyor for gentle, horizontal chip or scrap movement, especially machine-side or in-pit transport.

Rule of thumb:

  • Versatile & heavy-duty: Steel Belt

  • Sticky/oily stamping scrap: Pivot Belt

  • Horizontal chip transfer: Oscillating

Two machines, two different jobs. Here is how to tell them apart and when to use each.

A magnetic conveyor and a magnetic separator both use magnets to handle ferrous material, but they perform opposite functions. A magnetic conveyor is a material handling device that transports solid ferrous chips and parts. A magnetic separator is a fluid filtration device that pulls ferrous fines out of coolant. One moves metal. The other cleans fluid.

Quick Comparison

Magnetic Conveyor Magnetic Separator
Primary job Transports solid ferrous scrap Removes ferrous fines from fluid
Acts on Chips, slugs, turnings, small parts Coolant or cutting oil
Category Material handling and conveying Fluid filtration
Typical position Machine side, feeding downstream processing In the coolant loop, often as a pre-filter
Output Scrap delivered to a bin or processor Cleaner fluid returned to the process

 


Frequently Asked Questions

What is the difference between a magnetic conveyor and a magnetic separator?

The difference is what they act on. A magnetic conveyor transports solid ferrous scrap such as chips, stamping slugs, turnings, and small parts from the machine to downstream equipment or a container. A magnetic separator removes suspended ferrous fines and sludge from a fluid stream so the coolant or oil runs cleaner. A conveyor is used for material handling. A separator is fluid filtration.

What does a magnetic conveyor do?

A magnetic conveyor moves ferrous material cleanly and without carryover. PRAB uses a beltless slide design, with permanent magnets on a chain beneath a stationary stainless steel slider bed that grip the material and carry it to the release point, including up inclines. It is the right tool when the goal is to reliably move fine or thin ferrous scrap to a wringer, centrifuge, briquetter, or bin. See the full magnetic conveyor product page for models and configurations.

What does a magnetic separator do?

A magnetic separator removes ferrous contaminants from liquid. PRAB separators use a rotating drum fitted with ferrite or rare-earth magnets. As contaminated coolant or cutting oil flows across the drum, ferrous particles are captured and carried out of the fluid stream, and the cleaned fluid continues on. It is commonly used in grinding, honing, and gear cutting, and often runs as a pre-filter ahead of other fluid filtration equipment. PRAB ferrite models remove up to 97 percent of ferrous particles larger than 40 microns, and rare-earth models capture down to 15 microns, per PRAB published specifications.

Do I need a magnetic conveyor or a magnetic separator?

Choose based on the problem you are solving. If solid ferrous chips are piling up at the machine and need to be moved away cleanly, you need a magnetic conveyor. If your coolant is loaded with fine ferrous particles that hurt tool life and surface finish, you need a magnetic separator. Many operations end up using both because moving the scrap and cleaning the fluid are two separate goals.

Can I use a magnetic conveyor and a magnetic separator together?

Yes, and they often work as a pair. A magnetic conveyor handles the solid scrap leaving the machine, while a magnetic separator keeps the coolant clean in the same cell. Both feed the larger goal of recovering fluid and scrap value, which is where coolant recycling systems complete the loop.

Is a magnetic conveyor a type of filtration?

No. A magnetic conveyor is a conveying and material handling device, not a filtration device. It can help the coolant drain off the scrap as it moves, which reduces fluid carried away with the chips, but it does not filter the fluid itself. Removing particles from the fluid is the job of a magnetic separator or other fluid filtration equipment.

What kind of magnets does each one use?

Both use permanent magnets, but are configured differently. A PRAB magnetic conveyor uses ceramic magnets, with rare-earth available, mounted on a moving chain under a fixed slider bed to grip and carry solid scrap. A PRAB magnetic separator uses ferrite or rare-earth magnets inside a rotating drum to attract fine particles out of flowing fluid. The conveyor holds and transports. The separator attracts and extracts.

Which industries use each?

  • Magnetic conveyors: CNC machining, stamping, and grinding operations that generate ferrous chips, fines, and thin scrap that must be moved without spillage.
  • Magnetic separators: centerless and heavy stock removal grinding, honing, and gear cutting, where fine ferrous particles end up suspended in coolant.

For non-ferrous or mixed scrap that a magnet cannot hold, a steel belt conveyor is the appropriate transport choice instead of a magnetic conveyor.

How do I choose the right one for my operation?

Start by separating the two questions: how do I move the scrap, and how do I keep the fluid clean. For the scrap side, use PRAB’s conveyor selection tool or browse the full conveyor lineup. For the fluid side, the surest path is to test your actual coolant. PRAB offers free fluid testing for separator sizing and free materials testing for conveyor selection, so the equipment is matched to your real material rather than a generic profile.
