In today’s competitive manufacturing environment, efficient material handling isn’t optional; it’s essential. For metalworking facilities that handle chips, turnings, stamping off-cuts, and other scrap, the right conveyor system can drastically improve safety, uptime, and overall operational costs. But not all metal scrap conveyors are created equal. Choosing the right option depends on understanding scrap characteristics, coolant conditions, plant layout, and throughput requirements.
At PRAB, conveyors are engineered specifically for the harsh demands of industrial metal scrap handling, offering customizable solutions that integrate seamlessly with chip-processing and fluid-management systems. Below, we break down the key considerations and options to help you select the conveyor that best fits your needs.
Metal scrap conveyors automate the movement of scrap from machining centers, presses, and casting lines to centralized processing or recycling areas. Without proper conveyance, scrap accumulates, causing safety hazards, increased labor costs, and unexpected machine downtime. By automating this task, conveyors help:
PRAB’s conveyor portfolio includes multiple technologies tailored to different scrap types, coolant conditions, and plant layouts. Understanding these variations is critical to choosing the right system.
Best for: Wet and dry scrap, mixed materials, heavy and abrasive turnings.
Steel belt conveyors are often the first choice for general metal scrap handling due to their versatility and robustness. These systems feature heavy-duty hinged steel belts and abrasion-resistant components designed to withstand the most demanding environments. They move everything from bushy wads and die-cast trim to steel and aluminum turnings with minimal maintenance and high uptime.

Best for: Thin-gauge, oily, or stringy scrap that tends to cling to conveyor surfaces.
Pivot belt conveyors are engineered to eliminate the common issue of carryover (when scrap sticks to a belt and is carried where it shouldn’t). Their unique hinged design, rigidized surfaces, and reinforced framework make them a smart choice for operations with messy, hard-to-handle metal waste, such as stamping trim or oily slugs.
Key benefits include:
Best for: Hot, wet, or abrasive chips; horizontal transport.
Oscillating conveyors use vibration to move scrap smoothly along troughs. With fewer moving parts than belt systems, they offer low maintenance and high reliability, especially when moving chips directly at the machine interface or across short distances. Their quiet operation and minimal complexity make them an excellent choice for straightforward chip evacuation.
Best for: Heavy scrap, fines, and abrasive materials.
Drag conveyors feature tough drag chains with welded steel flights that pull material through abrasion-resistant troughs. They perform well in high-load applications where heavy metal chips, die casting trim, or stamping scrap must be moved reliably over longer distances or in submerged in-floor configurations.
In some cases, specific plant conditions call for specialized conveyors:
Each system addresses unique challenges related to space, coolant recovery, and material control.
The right choice starts with understanding your scrap type and coolant conditions. For example:
Assessing your throughput requirements and plant layout—such as horizontal vs. inclined conveyance—also influences which system will deliver the maximum uptime and the lowest lifecycle cost.
Selecting a conveyor isn’t just about throughput and scrap type—maintenance and integration matter too. A poorly chosen conveyor can increase belt wear, require frequent inspection, and disrupt fluid management systems.
PRAB conveyors are engineered to integrate with metal chip processing and coolant recovery systems, enabling automated scrap and fluid handling that boosts operational efficiency and reduces labor. PRAB
Regular maintenance planning—such as belt tension checks and replacement of worn parts—is essential for maximizing service life and minimizing downtime. Considering technology elements like automated greasing or sealed bearings will reduce maintenance intervals and improve uptime.
Metal scrap conveyors are a foundational piece of any efficient metalworking or manufacturing operation. Choosing the right conveyor system—based on scrap characteristics, coolant handling, throughput demands, and plant layout—can significantly impact productivity, safety, and operating cost.
PRAB’s range of conveyor technologies (including steel belt, pivot belt, oscillating, drag, and specialty systems) provide industry-tested solutions designed for longevity, low maintenance, and seamless integration with downstream processes.
