Corrugated Sidewall Belt Conveyor – Steep Angle Bulk Material Conveyor
Darko corrugated sidewall belt conveyor is designed for transporting all kinds of bulk materials such as ore, coal, aggregates and cement clinker. With corrugated sidewalls and cleats, it realizes 0°~90° high-incline and vertical conveying without material spillage.
What is a Corrugated Sidewall Belt Conveyor?
A corrugated sidewall belt conveyor, also referred to as steep angle cleated conveyor, is a professional bulk material transport device fitted with wave-shaped corrugated sidewalls and TC partition cleats on the base belt. It can convey bulk materials continuously at an inclination of 0° to 90° without material sliding or spillage. It can be arranged horizontally, in Z-type or S-type layouts without transfer points, which greatly saves floor space and construction costs. Widely used in cement plants, mines, quarries and port terminals, this heavy-duty conveyor is ideal for lifting cement clinker, ore, coal, aggregate and other bulk materials, and we can provide heat-resistant, flame-retardant and wear-resistant belts to adapt to various harsh working conditions.

- Key Advantages of Corrugated Sidewall Belt Conveyor
- Technical Parameters
- Application Scenarios
- Cases
- Equipped with Sidewalls and Cleats
Flexible corrugated sidewalls form material pockets. Matched with cleats, they prevent bulk material spillage on steep slopes.
- Variable Incline Conveying
The conveyor supports adjustable inclination angles and adapts to different industrial production lines.
- High Incline Conveying Capacity
It works stably above 30°, which ordinary troughed belt conveyors cannot achieve.
- Vertical Conveying Function
It lifts bulk materials vertically into silos and bins, simplifying the whole conveying system.
- Compact Steel Structure
The steep-angle layout greatly reduces the equipment footprint and saves construction cost.
- Dust Controlling Device Available
These conveyors handle various bulk materials, including coal, ore, aggregates, cement clinker and grains for mining, cement industry and port logistics. Sealed enclosures and dust suppression systems can be added as required.
