Bulk Material Handling Project for NEPEAN Conveyors
Managing the continuous, high-volume flow of raw extracted materials demands structural resilience, precise kinetic engineering, and rigorous environmental control. Commissioned by NEPEAN Conveyors and executing the design in joint collaboration with bulk handling experts L.E. Otten, KEVOS® developed a comprehensive engineering drafting package for overland conveyors, heavy transfer chutes, and high-impact crushing layouts optimized for the mining sector.
Executive Summary
project charter overviewTransporting raw, heavy materials across vast operational distances is a central challenge in modern mining and construction. Road-based haulage introduces excessive fuel costs, high emissions, and continuous maintenance downtime. In collaboration with L.E. Otten, our team delivered detailed mechanical design and drafting for a high-efficiency bulk material handling system for NEPEAN Conveyors. By engineering optimized transfer chutes, precision-aligned idlers, and rugged crushing station layouts, the project delivered a continuous-flow transport solution that drastically reduced logistical costs per ton while deliberately minimizing environmental dust and noise footprints.
Eliminate batch-based transport bottlenecks. A well-engineered conveyor system provides a continuous, highly predictable material yield that stabilizes downstream processing facilities.
- Analyze specific material properties (density, abrasiveness, flowability) prior to design.
- Design heavy-duty transfer chutes that prevent blockages and reduce material degradation.
- Incorporate active environmental mitigation through dust suppression and enclosed profiles.

Relationship Diagram
mechanical handling integrationsDependencies & Interactions
system boundariesTransfer chute angles depend on material flowability — sticky or wet ores require steeper drop angles to prevent structural blockages.
Conveyor belt width depends on target volume throughput — higher production requirements demand wider belts and increased drive power.
Maintenance schedules depend on wear liner specifications — specifying thick, hardened plates in impact zones reduces replacement frequency.
Environmental compliance depends on dust enclosure design — sealing transfer points tightly prevents fine powders from escaping into the air.
Structural stability depends on crusher vibration damping — heavy crushing layouts require massive steel foundations to absorb kinetic shocks.
Project success depends on expert collaboration — aligning with L.E. Otten ensured the drafting met complex, real-world bulk handling demands.
Key Takeaways
essential lessons- Conveyors dominate long distances — overland belt systems remain the most cost-effective way to move bulk material across harsh terrain.
- Understand the material first — you cannot design a functional chute without knowing the moisture, lump size, and density of the ore.
- Control the trajectory — calculating exactly where the material will land prevents costly belt tears and off-center tracking.
- Design for severe wear — incorporating replaceable, abrasion-resistant liners protects the permanent steel structures from destruction.
- Mitigate environmental impact early — designing dust suppression into the layout from day one ensures strict mining regulations are met.
- Versatility is a strength — well-designed conveyor layouts can handle solids, powders, and diverse materials with minimal adjustment.
- Collaboration elevates quality — partnering with specialists like L.E. Otten ensures designs are rooted in deep industry experience.
- Safety through automation — replacing truck fleets with conveyors dramatically reduces vehicle interactions and related safety risks on site.

Frequently Asked Questions
clarifying the design choicesWhy are conveyors preferred over haul trucks for long distances?
Conveyors offer continuous, non-stop material flow. They consume less energy per ton, require fewer personnel, eliminate diesel emissions, and don't require constant road maintenance, making them highly cost-effective.
What is the purpose of a transfer chute?
When material moves from one conveyor belt to another (often changing direction), it must be guided safely. A chute catches the flying material, controls its speed, and drops it gently onto the center of the next belt.
How did the design minimize environmental impact?
We designed enclosed transfer points and integrated dust suppression systems. This prevents fine powders and particulates from blowing away into the surrounding environment during high-speed transport.
What role did L.E. Otten play in this project?
L.E. Otten provided highly specialized industry expertise. We collaborated closely with them to ensure our CAD designs and structural layouts aligned perfectly with best practices for bulk material flow dynamics.
Why is material analysis done before drafting?
Different materials behave differently. Wet clay sticks to metal, while hard rock bounces. Knowing the material's density, moisture, and abrasiveness dictates the angle and thickness of the chute design.
What are wear liners and why are they used?
Wear liners are sacrificial, hardened metal plates bolted inside the chutes. They take the abrasive damage of the falling rock so the main structural steel remains intact, allowing for cheap, easy replacements.
