Quick Answer
A metal scrap conveyor is an automated system that moves metal chips, turnings, and swarf away from a machine tool to processing, storage, or load-out equipment. The right choice depends on four variables: scrap type, coolant load, throughput volume, and plant layout. PRAB offers 13 configurable conveyor types, including steel belt, drag chain, magnetic, oscillating, pneumatic, and screw conveyors, with service lives that routinely reach 20 to 30+ years and documented productivity gains of up to 50%.
Walk onto almost any CNC shop floor, stamping line, or die-casting operation, and you’ll find the same problem repeating itself at every machine: metal chips, turnings, and swarf piling up faster than anyone can shovel them. A metal scrap conveyor system solves that problem by automatically pulling scrap away from the point of production and routing it to processing, storage, or a load-out area. It sounds simple. It isn’t, because the scrap coming off a lathe looks nothing like the scrap coming off a stamping press, and a conveyor built for one will jam, wear out, or leak fluid all over the floor if you put it on the other.
PRAB builds 13 configurable conveyor types for this reason. Steel belt, drag chain, magnetic, oscillating, pneumatic, screw, and several specialty designs each target a specific combination of chip form, moisture level, and throughput. Picking the wrong one doesn’t just cost you money on the equipment. It costs you in downtime, in labor spent unjamming a conveyor that was never suited to your material, and in coolant that leaks out along the way instead of making it back to your Guardian coolant recycling system.
Most plants inherit their scrap-handling equipment the way they inherit everything else on the floor: it came with the building or the last machine-tool package, and nobody has revisited whether it still fits the operation. That’s a mistake because conveyors touch three things every plant manager cares about: safety, productivity, and cost.
On safety, manual scrap handling means forklift traffic weaving through the aisles, operators reaching into hoppers, and slip hazards from spilled coolant. Facilities that install the right conveyor for their application have documented worker safety improvements of up to 25%, largely by reducing the number of times workers have to physically touch hot, sharp, or oily scrap. In terms of productivity, PRAB conveyor installations have shown gains of up to 50%, mostly because scrap no longer backs up at the machine and interrupts production. And on cost, a properly specified system connects directly to downstream chip processing and fluid recycling equipment, so the fluid clinging to your scrap is recovered rather than hauled away and paid for twice.
If there’s one conveyor type that appears in the widest range of metalworking applications, it’s the steel belt conveyor. It handles wet or dry scrap, configures into straight, Z-style, or L-style layouts, and moves everything from bushy turnings to die scrap to small stamping chips. That versatility is why steel belt conveyors are usually the first system engineers evaluate when a new line goes in, even in shops that will eventually need a second, more specialized conveyor for a specific process.
That said, versatile isn’t the same as universal. Thin-gauge, oily stamping slugs tend to stick to a standard steel belt and carry over instead of dropping into the hopper, which is exactly the problem Pivot Belt conveyors were built to solve. Highly abrasive, wet chips do better on an oscillating conveyor, which uses vibration rather than a moving belt and holds up to 98% uptime in stamping operations. And when scrap has to travel long distances or overhead without floor-level routing, a pneumatic system beats a mechanical belt every time. The point isn’t that the steel belt is always right. It’s that steel belt that is the right starting question to ask, and the answer usually points you toward either the steel belt itself or a more specialized alternative for a specific bottleneck.
Rather than guessing, PRAB’s engineering team evaluates four variables before specifying any chip conveyor system, and this is the same framework any shop can use to narrow its own options:

Most PRAB conveyors start with standardized, heavy-duty core platforms rather than being built from scratch for every order. Those platforms are then configured, not reinvented, in partnership with your engineers and plant management to match your scrap, coolant, and floor plan. That’s a meaningfully different promise than “fully custom,” and it’s a better one: you get equipment with decades of field-proven design behind it, sized correctly for your specific application.
A conveyor rarely stands alone. Connected to a chip-processing system, it moves scrap directly to wringers, centrifuges, or briquetters, which recover up to 98% of the embedded cutting fluid before the chips ever leave the building. Connected to a Guardian Coolant Recycling System, that recovered fluid goes straight back into your machining operation instead of getting hauled off and replaced. This is what “closing the loop” actually means on a shop floor: scrap and fluid move through a single automated line rather than a chain of manual handoffs, each of which is an opportunity for spillage, delays, or lost coolant.
Because industrial scrap conveyor systems sit at the front end of that line, getting the conveyor selection right has an outsized effect on everything downstream. A conveyor that carries over too much coolant strains your wringer. One that jams on bushy turnings backs up production at the machine. Specifying the conveyor correctly the first time avoids a cascade of smaller problems later.
Before committing to a purchase, PRAB validates the application through free materials testing, running your actual scrap through the equipment you’re considering so you get real performance data rather than a spec-sheet promise. That testing, combined with the Performantee guarantee, is how PRAB backs claims of up to 50% productivity increases and up to 25% safety improvements without asking you to take those numbers on faith. Some PRAB conveyors installed decades ago are still running today, with the company still supplying parts for units sold more than 65 years ago, which says something about what “engineered for long service life” actually means in practice.
What’s the difference between a steel belt conveyor and an oscillating conveyor?
A steel belt conveyor moves scrap on a continuous moving belt and handles the widest range of chip types and layouts. An oscillating conveyor uses vibration instead of a belt and excels with hot, wet, or abrasive chips, particularly in stamping and die-casting operations where documented uptime exceeds 98%.
Can one conveyor handle mixed scrap types?
Sometimes, but it depends on how different the scrap streams are. A steel belt conveyor’s versatility makes it the most likely candidate for mixed loads, but shops running very different processes on the same line often end up specifying two conveyor types rather than forcing one system to handle everything.
How long does a metal scrap conveyor typically last?
Well-specified, heavy-duty conveyors routinely run 20 to 30 years in continuous production environments, with some documented installations still operating and supported after more than 65 years.
