Large Angle Corrugated Sidewall Conveyor Belt For Sand Grain Bulk Material Handling
Corrugated Sidewall Conveyor Machine
MWIN Corrugated Sidewall Conveyor Belt is a high-performance, heavy-duty conveyor belt engineered for large-inclination (0°-90°) and vertical bulk material handling. Manufactured by Qingdao MWIN Industry And Trade Co., Ltd., it integrates a robust base belt, flexible corrugated sidewalls, and reinforced transverse cleats to form enclosed material-carrying compartments, enabling efficient, spillage-free conveying in space-constrained environments. It is widely used in mining, cement, coal, ports, grain, and chemical industries, replacing traditional bucket elevators and complex multi-transfer systems.
The system integrates a standard rubber conveyor belt with flexible, continuous corrugated sidewalls that are vulcanized onto the belt edges. Transverse cleats (or flights) are then attached at regular intervals between the sidewalls, creating a series of sealed pockets or compartments. These pockets securely contain the material, preventing rollback and spillage during high-angle transport.
Key Components & Design Features
- Base Belt: The carcass provides the tensile strength. It is typically a rugged, flexible fabric or steel cord belt designed to handle the significant tension and flexing required for the system.
- Corrugated Sidewalls: Made of specially formulated, flexible rubber, these vertical walls are the defining feature. They are molded into a corrugated (wave-like) pattern, which provides excellent rigidity to contain the load while maintaining the flexibility needed to travel over the conveyor's pulleys.
- Cleats (Flights): These are the cross bars that form the back of each pocket. Cleats are sized and spaced according to the material size and incline angle. They bear the direct load of the material and provide the positive thrust for lifting.
- Specialized Pulleys and Idlers: The conveyor uses specially designed drives, bend pulleys, and idlers to accommodate the belt's unique profile, ensuring smooth transition from horizontal feeding to vertical lifting and back to horizontal discharge.
Primary Advantages
- Steep to Vertical Incline: Can convey materials at angles from 30 degrees up to 90 degrees (vertical), saving enormous amounts of floor space compared to long, low-angle conveyors or elevator systems.
- Continuous, High-Capacity Flow: Unlike bucket elevators which operate intermittently, it provides a continuous, smooth material flow with high capacity in a single, compact unit.
- Single-Belt System: Eliminates transfer points between a horizontal conveyor and an elevator, reducing dust, spillage, degradation of fragile material, and points of maintenance.
- Material Versatility: Can handle a wide range of bulk materials: free-flowing granules (plastic pellets, grains), powders (cement, fly ash), lumps (coal, ore, crushed stone), and even abrasive or hot materials (with appropriate belt specifications).
- Space Efficiency and Layout Flexibility: Ideal for confined spaces, existing plants, or applications where a straight-line path from intake to discharge point is needed over a significant elevation change.
Typical Applications
Mining & Quarrying, Power Plants, Cement Industry, Chemical & Fertilizer Plants, Ports & Terminals, Food & Grain Processing.
Configuration Types
- L-Type: Features a horizontal feed section leading into the inclined section. Most common configuration.
- S-Type: Has a horizontal tail, an inclined section, and a horizontal discharge section, forming an "S" shape. This provides a gentler transition and is better for very fragile materials.
- Z-Type: Similar to S-type but with two vertical bends, allowing both loading and discharge at the same elevation but at different horizontal points.

Frequently Asked Questions
Q1: What is the typical lifespan of a rubber conveyor belt?
A: The lifespan depends on several factors, including the material being transported, operating conditions, and maintenance practices. Generally, a well-maintained rubber conveyor belt can last between 3 to 5 years. However, in harsh environments (high heat, heavy abrasion), replacement may be needed sooner.
Q2: How do I choose the right conveyor belt for my application?
A: Selection depends on four key factors: Material (what are you transporting?), Environment (is it hot, oily, wet, or acidic?), Load & Distance (how heavy is the load and how long is the conveyor?), and Incline (does the belt need to move materials up a steep angle?).
Q3: What is the best way to store conveyor belts?
A: Conveyor belts should be stored in a cool, dry, and dark place, away from direct sunlight, rain, and chemicals. They should be kept in a rolled position (not folded) to prevent cracking or damage to the core. Avoid placing heavy objects on top of the rolls.
Q4: What are the methods for splicing (joining) conveyor belts?
A: There are two main methods: Mechanical Splicing (uses metal fasteners - quick and easy but may not be suitable for high-tension systems) and Vulcanization Splicing (uses heat and pressure to bond the ends - creates a smooth, strong, and seamless joint ideal for heavy-duty and long-distance systems).
Q5: Can you customize the size and specifications of the belts?
A: Yes. We offer customized solutions based on your requirements. You can specify the width, length, cover thickness, color, and rubber properties (such as heat-resistant, oil-resistant, or flame-retardant) to match your specific conveyor system.
