What is a Curved Belt Conveyor?

A curved belt conveyor (also known as a curve conveyor or belt curve conveyor) is designed to change the direction of product flow smoothly without interrupting the conveying process. Unlike straight conveyors, curved conveyor belts navigate turns—typically at 45°, 90°, or 180° angles—allowing for efficient use of floor space and seamless integration into complex production layouts.
Related terms: curved belt conveyor, curved conveyor belt, curve conveyor, curved conveyor systems, belt curve conveyor
Key Benefits:

Space Optimization: Maximize floor space by eliminating the need for transfer points

Smooth Product Flow: Gentle handling prevents product damage during directional changes

Flexible Layouts: Create efficient production lines that fit your facility layout

Reduced Transfer Points: Fewer transfers mean less risk of jams and product damage

Versatile Applications: Suitable for packaging, food processing, logistics, and manufacturing

Modern curved conveyors come in various materials like PVC, PU, and modular plastic, depending on the industry and the product being handled. These belts are motor-driven and often include sensors and automation-compatible features for enhanced functionality in smart warehousing and production environments.

How Curved Conveyor Belts Work

Curved belt conveyors use specialized belt designs and drive mechanisms to navigate turns while maintaining smooth, consistent product movement.

🔹 Tapered Roller Design

Many curved conveyors use tapered rollers beneath the belt. The rollers are slightly angled, with the outer edge rotating faster than the inner edge. This differential speed allows the belt to navigate curves smoothly without slippage or bunching.

🔹 Conical Drum Drive

Some designs use a conical drive drum at the curve exit. The drum’s varying diameter matches the belt’s speed differential across its width, ensuring even tension and preventing belt drift.

🔹 Modular Belt Curves

For tighter turns and heavy-duty applications, modular plastic belts with specialized curve modules are used. These interlocking modules naturally follow the curve path without requiring complex tensioning systems.

🔹 Belt Tracking Systems

Advanced curved conveyors incorporate automatic belt tracking to maintain proper alignment. Sensors and adjustable guide rails ensure the belt stays centered, even under varying loads.

🔹 Variable Speed Control

For applications requiring precise product positioning, variable frequency drives (VFDs) allow operators to adjust conveyor speed dynamically, ensuring smooth acceleration and deceleration through curves.

Key Design Considerations for Curved Belt Conveyors

When specifying a curved belt conveyor for your application, consider these critical factors:

1. Inner Radius： The inner radius determines how tight the curve can be. Tighter curves (with smaller radii) save space but may limit belt width and load capacity. General rule: inner radius should be at least 1.5x the belt width.

2. Belt Width： Wider belts provide more product support but require larger radii of curvature. Choose belt width based on your largest product dimension plus 50-100mm clearance on each side.
3. Product Characteristics
  • Rigid products (boxes, cartons): Can navigate tighter curves
  • Flexible products (bags, pouches): May require gentler curves to prevent deformation
  • Round products (bottles, cans): Need side guides to prevent rolling off during turns

4. Curve Angle

  • 45°: Gentle, minimal product disruption
  • 90°: Most common, balances space savings and product handling
  • 180°: Maximum space efficiency, requires careful product control

5. Speed Requirements： Higher speeds through curves require wider radii and more sophisticated belt tracking systems. For speeds above 15 m/min, consult our engineering team for optimal design.

Whether you’re in food, pharma, or freight, investing in the right curve conveyor belt setup can transform your workflow, save space, and boost your bottom line

What is the difference between a curved belt conveyor and a curved roller conveyor?
A curved belt conveyor uses a continuous belt surface to transport products through turns, providing better control and support for small or irregularly shaped items. A curved roller conveyor uses individual rollers and relies on gravity or powered rollers, which is better for heavy, rigid products like pallets or large boxes.
What curve angles are available for curved belt conveyors?

We offer standard curve angles of 45°, 90°, and 180°. Custom angles from 15° to 180° are also available for special applications. The most common configuration is the 90° curve, which creates right-angle turns in production lines.

How do I determine the right inner radius for my curved conveyor?

The inner radius depends on your belt width and product characteristics. As a general rule, the inner radius should be at least 1.5 times the belt width. For example, a 600mm wide belt requires a minimum inner radius of 900mm. Our engineering team can help you optimize this for your specific application.

Can curved belt conveyors handle inclines or declines?

Standard curved belt conveyors are designed for horizontal applications. For inclined or declined curves, we offer specialized designs with cleated belts or modular friction-top belts. Please to discuss your specific requirements.

What types of products can curved belt conveyors handle?

Curved belt conveyors can handle a wide variety of products, including boxes, cartons, bags, bottles, cans, trays, and small parts. The key is matching the belt width, curve radius, and belt surface to your product characteristics. Products should be stable and not prone to tipping during turns.

How fast can products move through a curved belt conveyor?

Typical speeds range from 10 to 25 meters per minute, depending on the curve radius, product characteristics, and belt type. Tighter curves generally require slower speeds to maintain product stability. For high-speed applications (25+ m/min), wider radius curves are recommended.

What maintenance is required for curved belt conveyors?
Regular maintenance includes:
  • Weekly: Visual inspection of belt tracking and alignment
  • Monthly: Lubrication of bearings and drive components
  • Quarterly: Belt tension adjustment and roller inspection
  • Annually: Comprehensive inspection and replacement of worn components
With proper maintenance, curved belt conveyors typically operate for 5-7 years before major component replacement is needed.
How much does a curved belt conveyor cost?
Pricing varies based on curve angle, belt width, radius, and customization. Standard 90° curved conveyors (600mm wide, 1000mm radius) typically range from $3,000 to $12,000. Custom or larger systems can range from $10,000 to $40,000+. for your specific requirements.
Can I integrate a curved belt conveyor with my existing straight conveyors?

Yes! Our curved belt conveyors are designed to integrate seamlessly with existing conveyor systems. We match belt height, speed, and control systems to ensure smooth product transfer. We can also retrofit existing systems with curved sections.

Do you provide installation and training?

Yes, we offer installation support, operator training, and maintenance training. For local installations, we can provide on-site support. For international projects, we offer remote installation guidance via video calls and detailed installation manuals.
