The corrugated sidewall belt conveyor, also known as a high angle belt conveyor, is an advanced bulk material conveying system designed to transport materials at steep inclines and even vertical angles up to 90 degrees. By integrating a base belt, corrugated sidewalls, and transverse cleats into a single unified structure through a secondary vulcanization process, this conveyor system achieves exceptional strength, flexibility, and long-term reliability.
Unlike conventional flat belt conveyors or patterned belts, the corrugated sidewall belt conveyor is capable of handling extreme elevation changes within a compact footprint. This makes it an ideal solution for industrial applications where space is limited, conveying angles are large, and continuous material flow is required.

One of the most important advantages of the corrugated sidewall belt conveyor lies in its advanced manufacturing process. The sidewalls, cleats, and base belt are bonded together using a secondary vulcanization technique, forming an integrated structure rather than mechanically attached components.
This process ensures:
No delamination between sidewalls and belt
No cleat detachment during long-term operation
High resistance to tearing and flex fatigue
Excellent adaptability to repeated bending and load changes
The resulting structure achieves a balance of rigidity and flexibility—strong enough to carry heavy loads while remaining flexible enough for smooth belt circulation.
The base belt provides tensile strength and forms the foundation of the conveyor. It can be reinforced with fabric or steel cords depending on load requirements.
Corrugated sidewalls prevent material spillage during steep or vertical conveying. Their flexible wave-like design allows smooth belt bending around pulleys.
Cleats divide the belt surface into compartments, ensuring stable material transport at high angles and preventing rollback.
Together, these components create a fully integrated high-angle conveying system.

The corrugated sidewall belt conveyor operates by using friction-driven pulleys to move the belt while the sidewalls and cleats retain material on the belt surface. As the belt transitions from horizontal to inclined or vertical sections, the flexible sidewalls and cleats maintain material stability without spillage.
This allows continuous conveying at any angle between 0° and 90°, eliminating the need for intermediate transfer points or additional conveying equipment.
Corrugated sidewall belt conveyors can be designed and customized to suit a wide range of applications.
Belt Width: 400 mm – 2000 mm
Sidewall Height: 40 mm – 400 mm
Cleat Height: 35 mm – 350 mm
Conveying Angle: 0° – 90°
Material Particle Size: ≤ 400 mm (no strict lower limit)
Conveying Capacity: 1 m³/h – 6000 m³/h
Belt Speed: 0.8 – 4.0 m/s
Base Belt Type: Fabric reinforced / Steel cord
Operating Temperature: -30°C to +80°C
All parameters can be customized according to material characteristics and site conditions.

The corrugated sidewall belt conveyor offers significant advantages over traditional conveying systems.
It allows steep-angle and vertical conveying in a single continuous process, reducing system complexity. The compact design minimizes floor space requirements and lowers civil construction costs.
With fewer transfer points, material loss, dust generation, and maintenance requirements are significantly reduced. The system also offers high conveying efficiency with relatively low power consumption.
Traditional flat belt conveyors and patterned belts are limited in conveying angle and often require multiple transfer points to achieve large elevation changes. This increases system complexity, maintenance costs, and energy consumption.
The corrugated sidewall belt conveyor overcomes these limitations by enabling direct high-angle conveying, providing a cleaner, more efficient, and more economical solution.

The corrugated sidewall belt conveyor can handle a wide variety of bulk materials, including coal, ore, sand, gravel, fertilizer, grain, clinker, and chemical products.
Its design accommodates materials with varying densities, moisture content, and particle sizes, making it a versatile solution for many industries.
Proper installation is critical for optimal performance. The conveyor frame must be installed on a stable foundation, and pulleys must be aligned precisely to ensure smooth belt tracking.
Special attention should be paid to the transition areas between horizontal and inclined sections to ensure smooth belt movement and reduce stress on sidewalls and cleats.
Before commissioning, check belt tension, pulley alignment, and material feeding conditions. During operation, ensure uniform material loading and avoid sudden overloads.
The conveyor is designed for continuous operation and does not require frequent manual adjustment under normal conditions.
Thanks to the integrated vulcanized structure, corrugated sidewall belt conveyors require minimal maintenance. Routine inspections focus on belt surface condition, cleat integrity, and pulley alignment.
With proper operation, the conveyor system offers long service life and stable performance, reducing downtime and operating costs.
