Introduction

Handling industrial scrap is already a challenge, but when that scrap is hot, wet, or abrasive scrap conveyors, the game changes entirely. These harsh materials can wear down conveyor systems quickly, cause unexpected breakdowns, and lead to costly downtime. However, with the right approach, you can keep things moving smoothly and avoid catastrophic failures.


In this article, we’ll look at what makes this type of scrap difficult to manage, common pitfalls, and smart strategies to keep your conveying system durable and dependable.

Why It’s So Challenging


Hot, wet, and abrasive scrap is common in industries like metalworking, foundries, and recycling. Here’s what makes it especially problematic:





  • Heat: Scrap can be extremely hot right off the production line. High temperatures can weaken belts, warp components, or create fire hazards.




  • Moisture: Wet material, whether from coolants or cleaning processes, can cause corrosion, slippage, and even clogging in poorly designed systems.




  • Abrasiveness: Sharp edges and heavy material rapidly erode belts, chutes, and drive components.




Put all three together, and it’s a perfect storm for equipment failure—unless you design your system right.



Key Features of a Scrap Conveyor That Can Handle the Heat


1. Choose the Right Conveyor Type


Not all conveyors are made equal. For harsh scrap conditions, consider:





  • Steel Belt Conveyors: Extremely durable, ideal for hot and abrasive material.




  • Drag Chain Conveyors: Enclosed systems that can move wet, sticky, and sharp scrap without issues.




  • Oscillating Conveyors: Great for gentle movement and handling high temperatures without belts.




2. Use Heat-Resistant Materials


Any conveyor that handles hot scrap must be built with heat-treated metals and high-temperature bearings. Rubber or plastic belts often can’t withstand the heat and may melt or degrade quickly.



3. Reinforced Components


Wear liners made of AR400 or AR500 steel can protect surfaces from sharp scrap and extend the lifespan of the system. Also, high-strength chains and rollers should be standard in any abrasive scrap handling setup.



Dealing With Water and Moisture


When wet scrap is involved, corrosion becomes a major issue. Here are some best practices:





  • Use Stainless or Galvanized Steel: These resist rust and corrosion much better than carbon steel.




  • Design for Drainage: Make sure the system can drain liquids effectively to prevent pooling and stagnation.




  • Sealed Bearings and Motors: Keep sensitive parts protected from moisture ingress.




Additionally, enclosed conveyor systems help keep water from splashing out and creating safety hazards in the work area.



Smart Maintenance = Long Life


Preventing failure isn’t just about buying better equipment—it’s about taking care of it too.





  • Regular Inspections: Watch for signs of wear like thinning steel, belt cracks, or chain slack.




  • Lubrication: Especially important when dealing with heat and friction.




  • Clean-Out Access: Make sure your system is easy to clean and maintain, especially when handling wet or sticky scrap.




Upgrading to systems with predictive maintenance technology—like vibration sensors and load monitors—can alert you before a breakdown occurs.



Advanced Options Worth Considering




  • Magnetic Conveyors: For handling ferrous materials, these can move hot scrap without physical contact, reducing wear.




  • Hydraulic or Pneumatic Conveyors: Useful in environments where mechanical parts are too prone to damage.




  • Variable-Speed Drives: Adjust flow rate based on scrap load, reducing stress on the system.




Investing in modern conveyor controls not only boosts efficiency but also extends equipment life.



Conclusion


Conveying hot, wet, and abrasive scrap is tough—but it doesn’t have to be a constant source of failure. By choosing the right conveyor system, using durable and heat-resistant materials, and following smart maintenance practices, you can keep your operation moving smoothly and safely.


Upfront investment in rugged equipment and good design always pays off by reducing downtime, maintenance costs, and the risk of total system failure.
