corrugated sidewall conveyor belts are specially designed Conveyor Belt systems used for vertical or steep-angle conveying of bulk materials. Unlike conventional flat conveyor belts, corrugated sidewall conveyor belts are equipped with corrugated sidewalls and cross cleats, allowing materials to be conveyed at angles ranging from 30 degrees up to 90 degrees. This unique structure enables efficient material transport in limited spaces while preventing spillage and material rollback.
Corrugated sidewall conveyor belts are widely used in industries where space optimization, high lifting height, and continuous conveying are required. Typical applications include mining, cement plants, power stations, ports, metallurgy, chemical plants, and bulk material handling terminals. These belts offer a compact, reliable, and cost-effective alternative to bucket elevators and complex transfer systems.

A corrugated sidewall conveyor belt is a composite conveyor belt system consisting of three main components: a base belt, corrugated sidewalls, and transverse cleats. The base belt provides tensile strength and driving force, while the corrugated sidewalls prevent material spillage. The cleats divide the belt into compartments, ensuring stable material transport even at steep angles or vertical positions.
This design allows bulk materials to be conveyed smoothly without requiring multiple transfer points, reducing system complexity and maintenance costs.
Corrugated sidewall conveyor belts offer several technical and operational advantages compared with traditional conveying systems.
One of the most significant advantages is space efficiency. By enabling steep-angle or vertical conveying, these belts reduce the horizontal footprint of Conveyor Systems, making them ideal for installations with limited space.
Another advantage is high conveying efficiency. Materials can be transported continuously without spillage, even at high lifting heights. This reduces material loss and improves overall system productivity.
In addition, corrugated sidewall conveyor belts provide flexible system layout, allowing horizontal, inclined, and vertical conveying to be combined within a single belt system.
The performance of a corrugated sidewall conveyor belt depends heavily on its structural design and material quality.
The base belt serves as the load-bearing and driving component of the system. It can be reinforced with polyester fabric, nylon fabric, or steel cords, depending on load requirements and conveying distance. The base belt is typically designed with low elongation and high tensile strength to ensure stable operation.
The corrugated sidewalls are flexible rubber structures bonded to the edges of the base belt. Their accordion-like shape allows the belt to pass smoothly around pulleys while maintaining sufficient stiffness to contain materials. Sidewall height can be customized to suit different conveying capacities and lifting heights.
Cross cleats are attached perpendicular to the belt direction and act as partitions to hold materials in place. Different cleat shapes and heights are available depending on material characteristics and conveying angle.

Corrugated sidewall conveyor belts can be customized to meet various industrial requirements. Typical parameters include:
Belt Width: 400 mm – 2400 mm
Sidewall Height: 40 mm – 600 mm
Cleat Height: 30 mm – 500 mm
Cleat Spacing: Customized
Base Belt Tensile Strength: 160 N/mm – 8000 N/mm
Maximum Conveying Angle: 30° – 90°
Conveying Capacity: Customized based on material density and speed
Operating Temperature: -20°C to +80°C (higher with special compounds)
All belts are designed and manufactured according to project-specific requirements.
Different configurations are available to match specific application needs.

Corrugated sidewall conveyor belts are used in a wide range of industries.
Used for vertical and inclined conveying of coal, ore, and mineral materials, especially in underground and confined spaces.
Applied in clinker transport, raw material lifting, and finished product handling.
Used for coal lifting and ash handling systems.
Ideal for ship loading and unloading systems where space is limited.
Used for vertical transport of powders and granules.

Compared with bucket elevators, corrugated sidewall conveyor belts offer continuous operation, higher efficiency, and lower maintenance requirements. Compared with traditional inclined belt conveyors, sidewall belts allow much steeper conveying angles without material spillage.
These advantages make corrugated sidewall conveyor belts a preferred solution for modern bulk Material Handling Systems.
Proper installation is essential to ensure reliable performance.
Before installation, conveyor structures should be checked for alignment and rigidity. The belt must be installed carefully to avoid damaging sidewalls or cleats. Special attention should be paid to pulley diameters and transition zones to ensure smooth belt movement.
After installation, a test run without load should be conducted to verify tracking and stability.
During operation, materials should be fed evenly into the conveyor system. Sudden overloading should be avoided. Conveyor speed should be optimized to ensure stable material containment and prevent overflow.
Proper monitoring during operation helps identify potential issues early and ensures long-term reliability.
Regular maintenance helps maximize the service life of corrugated sidewall conveyor belts.
Inspect sidewalls and cleats for wear or detachment
Check belt tension and alignment
Remove material buildup regularly
Inspect pulleys and rollers
Preventive maintenance reduces downtime and extends belt life.
Sidewall Damage
Often caused by improper installation or sharp materials.
Material Spillage
May result from incorrect cleat height or uneven feeding.
Belt Deviation
Usually caused by misaligned conveyor components.
Timely inspection and corrective measures help maintain stable operation.
Key factors include conveying angle, material characteristics, capacity requirements, space constraints, and environmental conditions. Selecting the appropriate base belt strength, sidewall height, and cleat configuration is critical to system performance.
