One of the most difficult materials we have handled wasn’t coal. It was dried leaves.

In a project executed for Sun Pharma, the material had an extremely low bulk density of around 80–100 kg/m³.

And that creates a very different conveying challenge.

Low-density material means much higher material volume for the same TPH. Add changing material characteristics, and suddenly feeding behaviour, volumetric capacity, containment, and flow consistency become critical design parameters.

This is why conveyor selection should never begin with TPH alone.

Two materials may have the same mass flow rate and still require completely different conveying solutions.

Understand the material first. Engineer the conveyor second.

Because unusual bulk materials rarely fail on capacity alone—they fail when their actual behaviour is underestimated.

At 75° inclination, gravity is working against your conveyor every second.

Our steepest executed High-Angle Belt Conveyor is approximately 75°, and at that angle, simply increasing cleat height is not enough.

The material has to enter the belt correctly.
The pockets need to fill properly.
Rollback has to be controlled.
Transitions need to be engineered carefully.
And the entire conveyor must remain aligned under continuous operation.

That is why we treat steep-angle conveying as a specialized engineering discipline within belt conveying.

The 75° angle is only the number visible on the drawing.

The real engineering is making the system perform reliably every day.

If you are evaluating a high-angle conveying application, the discussion should go far beyond inclination alone.

Coal and biomass behave nothing alike. Yet sometimes, the same conveyor has to handle both.

That is where high-angle conveying becomes an application-engineering challenge.

We have executed High-Angle Belt Conveyors designed to handle both coal and biomass through the same system.

And you cannot design such a conveyor around a single bulk density or one set of flow characteristics.

When the fuel changes, so does the material volume, feeding behaviour, containment requirement, and overall conveying duty.

A conveyor that performs perfectly with coal but becomes difficult to operate when the plant switches to biomass has not been designed for the complete requirement.

The system needs to be engineered around the actual operating envelope—not just one material condition.

Because multi-fuel capability is not simply about whether the conveyor can move both materials.

It is about whether it can handle both reliably when the plant needs to switch.

When someone says they can manufacture a High-Angle Belt Conveyor, I ask one question: Where is it running?

Because for difficult conveying applications, references matter.

At , we have executed high-angle conveyors across a wide operating range:

Belt widths: 500 mm to 1600 mm
Capacity: 5 TPH to 100 TPH
Inclination: up to 75° Materials handled: coal, biomass, minerals, wood chips, bagasse, dried leaves, and more

Every material behaves differently. Every application brings its own challenges in feeding, containment, rollback control, belt tension, cleat selection, and discharge.

That is why high-angle conveying cannot be judged only by drawings or specifications.

For difficult conveying equipment, demonstrated application experience matters more than claims.

5 signs your High-Angle Conveyor may not be engineered correctly

Early cleat damage.
Excessive material spillage.
Material rollback.
Repeated splice failures.
Faster-than-expected belt wear.

These may look like separate maintenance issues, but the root cause is often somewhere deeper in the system.

Poor feeding, incorrect belt or cleat selection, unsuitable geometry, alignment issues, and improper belt tension can all contribute to repeated failures.

That is why a High-Angle Belt Conveyor must be engineered as one complete system—not treated as a collection of individual components.

Fixing one component may solve the symptom.

Correcting the system design solves the problem.

If you are repeatedly troubleshooting the same high-angle conveyor issues, it may be time to look beyond the component that keeps failing.

What if the same 36-metre lift could need 111 metres of horizontal space—or just 10?

That is exactly why High-Angle Belt Conveyors can completely change a plant layout.

From pure geometry, a 36-metre vertical lift at 18° requires roughly 111 metres of horizontal distance** before considering transitions and other design requirements.

At 75°, that horizontal requirement drops to around 10 metres.

For plants where space is limited, that difference can be significant.

Instead of stretching the conveyor across a large portion of the site, high-angle conveying allows the layout to move vertically—helping reduce the conveyor footprint and opening up more flexibility in plant design.

That is why high-angle conveying is not only about achieving a steeper inclination.

It can fundamentally change how the entire plant is planned.

If layout space is your constraint, high-angle conveying may be worth evaluating.

One conveyor. Two very different fuels. 22 metres of lift at 75°.

That is where high-angle conveying becomes an application-engineering challenge.

In one of our installations at Rollcon, the same High-Angle Belt Conveyor handles both coal and biomass using a corrugated sidewall cleated belt.

And that changes the design approach completely.

Coal and biomass behave very differently, so the system has to be engineered to feed, contain, elevate, and discharge both materials reliably across varying operating conditions.

With approximately 22 metres of vertical lift and a 75° inclination, every element—from feeding and belt selection to cleat geometry, containment, tracking, and discharge—has to work as one integrated system.

Projects like this are exactly why high-angle conveyors cannot be selected from a catalogue.

They have to be engineered around the application.

A High-Angle Belt Conveyor is not a normal belt conveyor tilted to 75°.

That is one of the biggest misconceptions in steep-angle conveying.

As the inclination increases, the entire engineering philosophy changes—material feeding, cleat selection, sidewall design, rollback control, belt tension, transition geometry, tracking, and discharge arrangement all have to work together.

Get even a few of these wrong, and the result can be spillage, damaged cleats, premature belt wear, or splice-related issues.

The belt itself is only one component.

The real product is the engineering behind the complete conveying system.

If you are evaluating a high-angle conveying application, design the system around the material and process—not just the required angle.

36 metres of lift. 75° inclination.

This is where conveyor engineering moves beyond standard design.

At Rollcon , we have already commissioned a High Angle Belt Conveyor with a vertical lift of up to 36 metres, and executed 8 such conveyors across different applications.

At these inclinations, it is not simply a conventional belt conveyor tilted upwards.

The entire system has to be engineered together—feeding arrangement, cleats, sidewalls, belt tension, transition zones, tracking, and material rollback control—to ensure reliable conveying at steep angles.

That is why we don't treat high-rise conveying as a catalogue product.

We treat every high-lift application as an engineering problem that needs the right solution.

Have a challenging high-lift conveying requirement?
That’s exactly the kind of application we like solving.

Can one metre really make a difference in a Travelling Tripper?

In many material handling plants, absolutely.

A tripper stopping at the wrong position can lead to uneven bunker filling, poor stockpile formation, additional reclaiming effort, and repeated operator intervention.

And when these small positioning errors happen every day, they eventually become significant operating costs.

That is why Travelling Tripper engineering goes far beyond the mechanical structure. It requires the right combination of positioning accuracy, travel logic, discharge control, and distribution philosophy.

Every stop and every discharge point must be designed around the process—not simply the physical layout.

Because in bulk material handling, precision is not only about how accurately the machine stops.

It is about how efficiently the entire plant operates because of it.
