Large Angle Rib Belt Conveyor, Skirt Conveyor & Steep Incline Conveyor System
1. Large Angle Rib Belt Conveyor Overview

A large angle rib belt conveyor is designed to transport bulk materials at steep inclines while helping prevent material from sliding or spilling backward. Also known as a corrugated sidewall belt conveyor or steep angle conveyor, this system uses a specially designed belt with raised sidewalls and cross cleats to retain materials during elevation changes.

Unlike conventional flat belt conveyors, large angle rib belt conveyors can move materials through limited vertical space and across significant height differences. They are widely used in mining, cement production, power plants, ports, chemical processing, agriculture, and bulk material handling facilities.

A skirt conveyor is commonly associated with material containment and controlled loading. Skirt boards or skirt rubber are installed along selected conveyor loading sections to help prevent material spillage and guide bulk materials onto the belt. Depending on the project, skirt components may be used alongside a corrugated sidewall belt or a conventional conveyor system.

Our large angle rib belt conveyor and skirt conveyor solutions can be configured according to material properties, conveying capacity, lifting height, installation layout, and operating conditions. The appropriate design helps support continuous transportation and efficient use of available plant space.

2. What Is a Large Angle Rib Belt Conveyor?

A large angle rib belt conveyor is an inclined conveying system that uses a belt equipped with corrugated sidewalls and transverse cleats. The sidewalls form flexible barriers along both edges of the belt, while the cleats create compartments or pockets that hold materials as the belt moves upward.

The corrugated sidewalls help contain bulk materials, and the cleats provide additional support against gravity. This construction allows the conveyor to transport selected materials at much steeper angles than ordinary flat belt conveyors.

Depending on the application, the belt may be configured with different sidewall heights, cleat profiles, belt widths, and rubber compounds. The system may also incorporate horizontal sections for feeding and discharge.

Large angle rib belt conveyors can be designed for different bulk materials, including coal, limestone, sand, gravel, fertilizer, grain, and selected ores. The actual maximum conveying angle depends on material characteristics, cleat design, belt speed, and system configuration.

3. Main Components of a Large Angle Rib Belt Conveyor
Corrugated Sidewall Belt

The corrugated sidewall belt is the main conveying component. Flexible sidewalls are bonded or otherwise integrated with the belt to create barriers that help retain material during inclined transportation.

Sidewall height and construction should be selected according to the material size, conveying angle, and required capacity.

Transverse Cleats

Cleats are installed across the belt at specified intervals. They help support the material and reduce backward movement during steep incline conveying.

Different cleat shapes and heights are available for different material characteristics and conveyor arrangements.

Skirt Board and Skirt Rubber

Skirt components are typically installed along loading zones to guide incoming material and reduce spillage. Skirt rubber can help create a controlled contact interface between the loading area and the belt.

Correct skirt positioning and adjustment are important. Excessive contact pressure may increase belt wear and friction.

Drive Unit

The drive unit includes the motor, gearbox, drive pulley, and associated components. It provides the torque needed to move the loaded belt and overcome conveying resistance.

Drive specifications depend on conveyor length, lifting height, material load, belt speed, and operating duty.

Supporting Structure and Rollers

The conveyor frame, pulleys, and supporting rollers maintain the belt path and carry the operating loads. Their configuration depends on the conveyor's geometry and whether it includes horizontal, inclined, or curved sections.

4. What Is a Skirt Conveyor?

A skirt conveyor generally refers to a belt conveyor equipped with skirt boards or skirt rubber along the loading area to help control material flow and reduce spillage.

When bulk materials are transferred from a chute, hopper, feeder, or upstream conveyor, the incoming stream may spread beyond the belt edges. Skirt boards create a controlled loading channel, helping guide the material onto the belt and reduce losses.

Skirt conveyor arrangements are common in mining, quarrying, cement plants, power stations, grain handling, and industrial bulk material transfer.

A skirt conveyor is not necessarily a steep angle conveyor. Skirt boards are primarily used for material containment at loading points, whereas corrugated sidewalls and cleats are the principal components that enable steep incline conveying. Both features may be incorporated into a larger material handling system where appropriate.

5. Applications of Large Angle Rib Belt Conveyors

Mining and Mineral Processing

Large angle conveyors can transport coal, ore, crushed rock, and other minerals from lower working areas to elevated processing equipment or stockpiles. Their compact layout can be useful where installation space is restricted.

Cement and Building Materials

Cement plants and building material facilities handle limestone, clinker, sand, and other bulk materials. Steep incline conveyors can transfer materials between storage, processing, and feeding stages.

Coal and Power Plants

Selected coal and bulk fuel handling systems use inclined conveyors to move material between unloading points, storage areas, feeders, and processing equipment.

Ports and Bulk Terminals

Bulk material terminals may use steep incline belt conveyors to transfer materials between ship unloading equipment, storage facilities, and downstream handling systems.

Agriculture and Grain Handling

Suitable conveyor configurations can transport grain, seeds, feed, and selected agricultural materials between storage and processing equipment. Belt and cleat selection should reflect the material's flow and handling characteristics.

Chemical and Fertilizer Production

Inclined belt systems can transfer fertilizer, granules, and other selected bulk materials. Material compatibility, contamination control, and cleaning requirements should be considered during design.

6. How a Large Angle Rib Belt Conveyor Works

The conveyor operates by moving material inside the compartments formed by its sidewalls and transverse cleats.

Step 1: Material Feeding

Bulk material enters the conveyor through a hopper, chute, feeder, or another controlled loading device. Skirt boards may guide the material and reduce spillage at the loading point.

Step 2: Material Retention

As the belt begins to incline, the corrugated sidewalls help prevent material from escaping over the edges. Transverse cleats support the material and form compartments that reduce backward movement.

Step 3: Inclined Transportation

The drive unit moves the belt along the conveyor structure. The cleats carry the material upward, while the sidewalls help maintain containment throughout the inclined section.

Step 4: Material Discharge

At the discharge point, the conveyor geometry and pulley arrangement allow material to leave the belt and enter a receiving chute, hopper, silo, or downstream conveyor.

Step 5: Belt Return

The empty belt travels back along the return section. The return arrangement is designed to accommodate the belt's sidewalls and cleats while maintaining suitable belt tracking and support.

7. Advantages of Large Angle Rib Belt Conveyors
Steep Incline Material Transportation

Corrugated sidewalls and cleats allow suitable bulk materials to be conveyed at steep angles, potentially reducing the need for multiple conventional conveyors.

Efficient Use of Space

The system can combine horizontal and inclined conveying sections in a compact layout, helping accommodate facilities with limited installation space.

Reduced Material Spillage

Sidewalls and appropriately designed cleats help contain material during inclined transportation. Skirt boards at loading points provide additional control over incoming material.

Flexible System Configuration

Belt width, sidewall height, cleat dimensions, and conveyor geometry can be selected according to the application and required conveying capacity.

Continuous Bulk Material Handling

When correctly integrated with feeding and discharge equipment, the conveyor can support continuous transportation between different stages of production.

Adaptation to Different Industries

Large angle rib belt conveyors can be engineered for various bulk materials, provided the belt construction and system design match the material's physical properties and operating environment.

8. How to Choose the Right Large Angle Rib Belt Conveyor

Choosing the appropriate conveyor requires consideration of both material properties and plant layout.
