PRAB drag conveyor systems provide rugged, enclosed scrap handling for highly abrasive materials, such as cast-iron turnings and heavy-metal fines. With abrasion-resistant flight bars, a forged-steel chain, and liquid-tight trough construction, these conveyors are built to withstand harsh metalworking conditions while minimizing dust and coolant leakage. Their design supports long service life and low total cost of ownership, making PRAB drag conveyors a dependable choice for machining, grinding, and metal foundry scrap applications.
Our drag conveyors are built for the harshest scrap handling jobs—wet, heavy, sharp, or abrasive. Thick steel flights, heavy-duty chains, and abrasion-resistant liners enable these systems to experience 50% fewer unscheduled failures and up to twice the service life of standard drag conveyors. Whether your plant is located in North America or Europe, PRAB provides the same level of robust engineering, built in the USA or at our European headquarters in Poland, ensuring fast and reliable regional support.
These systems use powerful drag chains with welded steel flights to pull material along a hardened trough, making them ideal for conveying bushy turnings, stamping scrap, die-cast trim, and even dry sludge or fines. PRAB drag conveyors are built tough: the chains and flights are made of wear-resistant steel to ensure long-lasting durability, and the conveyor trough is abrasion-resistant to withstand continuous metal scraping.
Our designs feature sealed construction to contain dust or coolant and can be configured for horizontal or inclined transport, including in-floor submerged applications. They integrate seamlessly with automated scrap processing lines and are engineered to minimize spillage and prevent unplanned downtime, even in harsh, high-load environments.
With minimal moving components and slow chain speeds, drag conveyors deliver reliable, low-maintenance operation even when moving heavy loads or sharp, abrasive scrap. Automotive stamping, metal recycling, and machining companies rely on PRAB drag conveyor systems to reduce manual handling and downtime. Choose a PRAB drag conveyor when you need a proven, robust solution to move large volumes of scrap safely and efficiently.
PRAB offers two models, Series #348 and Series #458, in three configuration styles designed to convey materials for metal scrap recycling ranging in weight and bulk density. This conveyor is also available with in-feed hoppers and metering plates and can be customized with coolant pumps for integration with a metal chip and fluid filtration system.

PRAB Builds Equipment for the Toughest Jobs in Manufacturing and Metalworking
“Keeping up with high Q rates” sounds like the title of a reality TV show. It’s definitely an important aspect of any industrial manufacturing operation that puts a priority on optimizing output. If the goal is to machine as many parts as possible in the shortest amount of time to maximize profitability, a high material removal rate (Q) is critical […]
The forklift truck is standard equipment for many industrial manufacturing operations that need to move enormous amounts (read: tons) of material from point A to point B, day in and day out. Most of these operations probably feel like they can’t live without forklifts. However, the convenience and expediency they provide, in addition to sparing workers the task of lifting […]
There isn’t an employer in existence that shouldn’t consider slips and falls to be a significant safety concern in its facilities. In an article about overlooked hazards and risk zones in the workplace, Facility Executive magazine cites some sobering numbers: Same-level slip and fall accidents are the leading cause of workplace injuries and totaled almost 200,000 in 2015, according to […]
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.
| 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 |
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.
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.
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.
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.
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.
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.
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.
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.
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.
Not sure which one fits, or whether you need both? Contact an expert at PRAB, or explore magnetic conveyors and magnetic separators to compare them side by side.
