Bulk Material Handling in Mining | ROM, Conveyors & Transfer Engineering

Bulk material handling is at the core of almost every mining operation. From the moment raw material is extracted at the Run-of-Mine (ROM) pad through to crushing, screening, processing, and stockpiling, the safe and efficient movement of material is critical to productivity, asset reliability, and worker safety.

At Hamilton By Design, we support mining and heavy-industry clients with engineering-led mechanical design, verification, and documentation for bulk material handling systems—focusing on conveyors, transfer points, chutes, ROM bins, hoppers, and associated steelwork.

What Is Bulk Material Handling in Mining?

Bulk material handling refers to the mechanical systems used to move large volumes of raw or processed material, including:

Run-of-Mine (ROM) ore
Crushed rock and coal
Overburden and rejects
Processed product and fines

These systems typically include:

Apron feeders and ROM bins
Primary, secondary, and tertiary crushers
Conveyor belts and transfer stations
Chutes, hoppers, and bins
Stackers, reclaimers, and stockpiles

Each interface between machines is a design-critical point where poor geometry, misalignment, or incorrect loading assumptions can lead to blockages, excessive wear, spillage, downtime, and safety risks.

Engineering Challenges in Bulk Material Handling

Bulk handling systems operate under harsh conditions and face unique engineering challenges:

1. Variable Material Properties

Changes in moisture content, particle size, and bulk density
Segregation and fines generation
Adhesion and carryback issues

2. Transfer Point Design

Impact loading and wear at chute inlets
Flow control and trajectory management
Dust, spillage, and maintenance access

3. Structural and Mechanical Loads

Dynamic loads from material flow
Belt tensions and starting/stopping forces
Fatigue in steelwork and supports

4. Brownfield Constraints

Existing plant geometry and limited space
Legacy drawings that don’t reflect as-built conditions
Shutdown-driven installation windows

These challenges reinforce why engineering-led design, supported by accurate site data, is essential.

From ROM to Processing: A System-Based Engineering Approach

Hamilton By Design approaches bulk material handling as a complete system, not isolated components.

Our typical workflow includes:

Engineering-led site verification
Using high-accuracy 3D LiDAR scanning to capture existing conditions at ROM pads, conveyors, and plant interfaces.
Mechanical and structural design
Developing fit-for-purpose conveyor layouts, transfer chutes, supports, and access platforms using SolidWorks-based workflows.
Load definition and verification
Applying realistic material loads and operational scenarios to reduce over-design and manage fatigue risk.
Fabrication-ready documentation
Producing drawings and models that support fit-first-time fabrication and installation during shutdowns.

This integrated approach reduces rework, delays, and operational risk.

Conveyor Transfer Points: Where Most Problems Begin

Transfer points are the highest-risk locations in bulk material handling systems.

Common issues include:

Poor material trajectory control
Excessive impact and liner wear
Dust escape and spillage
Restricted inspection and maintenance access

Engineering-led transfer design considers:

Material flow paths and impact angles
Chute geometry and liner selection
Maintenance clearances and access
Compliance with guarding and safety standards

Well-designed transfer points improve availability, reduce maintenance costs, and enhance safety outcomes.

Why Engineering Matters More Than Ever in Mining Handling Systems

As mining operations push for higher throughput and tighter shutdown schedules, the tolerance for design error is shrinking.

Engineering-driven bulk material handling delivers:

Predictable material flow
Reduced downtime and blockages
Improved safety and maintainability
Defensible design records for audits and compliance

This is especially important in brownfield mining environments, where assumptions based on outdated drawings can introduce significant risk.

AS ISO 10816 & 20816 – Mechanical Vibration | Hamilton By Design

Mechanical vibration is one of the earliest indicators that rotating equipment is developing a fault. Standards such as AS ISO 10816 and AS ISO 20816 provide a consistent framework for measuring, evaluating, and managing vibration in industrial machinery.

At Hamilton By Design, we help clients apply these standards in a practical, engineering-led way by connecting vibration data with mechanical design, asset condition, and real-world site conditions.

What Are AS ISO 10816 and AS ISO 20816?

The AS ISO 10816 / 20816 standards define:

How mechanical vibration should be measured on machines
How vibration severity should be evaluated
What vibration levels are considered acceptable, marginal, or unacceptable

These standards are commonly applied to motors, pumps, gearboxes, compressors, fans, conveyors, and other rotating equipment where vibration provides an early warning of mechanical or structural issues.

Why Mechanical Vibration Standards Matter

Using vibration data without a recognised standard often leads to inconsistent interpretation and delayed action. Applying AS ISO 10816 / 20816 helps organisations to:

Identify mechanical problems early
Reduce unplanned downtime and breakdowns
Prevent secondary damage to bearings, shafts, and foundations
Improve overall equipment reliability
Support condition-based and predictive maintenance strategies

When vibration is assessed against an accepted standard, maintenance decisions become clearer and more defensible.

The Common Gap: Vibration Data Without Engineering Context

Many sites collect vibration data but struggle to connect it to:

As-installed geometry and alignment
Structural stiffness and support conditions
Design intent versus site reality
Maintenance and modification history

Vibration issues are often symptoms of broader mechanical or structural problems. Without engineering context, vibration data alone can be misleading.

This is where vibration assessment benefits from being connected to engineering-grade site information.

How Hamilton By Design Helps

Hamilton By Design connects vibration standards with practical engineering outcomes through a coordinated service offering.

Engineering-Led Vibration Interpretation

We assess vibration results against AS ISO 10816 / 20816 using engineering judgement rather than relying solely on alarm limits. Machine type, operating duty, and site conditions are all considered.

Understanding the Physical Asset

By linking vibration data with mechanical layouts, drawings, and 3D models, we help identify whether vibration is driven by alignment issues, inadequate stiffness, foundation behaviour, or design constraints.

Clear, Usable Reporting

Our reporting focuses on:

What the vibration levels indicate
Why the issue matters to the asset
What actions are recommended

This ensures vibration results directly support maintenance and engineering decisions.

Where This Approach Adds Value

A connected vibration and engineering approach is particularly valuable in:

Mining and mineral processing plants
Heavy industrial facilities
Energy and utilities infrastructure
Brownfield upgrades and asset life-extension projects

Vibration issues are frequently linked to steelwork design, support conditions, or historical modifications that were not fully engineered.

Summary

AS ISO 10816 and AS ISO 20816 provide the benchmark for assessing mechanical vibration.
Hamilton By Design provides the engineering connection that turns those benchmarks into practical action.

By linking vibration data with 3D scanning, mechanical design, and engineering analysis, vibration assessments become clearer, more accurate, and far more useful across the asset lifecycle.
