Not every transport line requires the same type of conveyor or surface geometry. In many cases, choosing the wrong belt or surface can compromise the efficiency of the line, accelerate wear, and shorten the system’s service life. In this second article of the Bellt Correntes technical series, we explore the main types of conveyor belts and surfaces, and how to select the most suitable option for your operation.

Bellt Conveyor Belts: Families and Functions
Bellt Correntes offers two main product families:

1. Chain Belts from the B-top and B-flex Series
Designed for straight or curved applications, these chain belts are available in both plastic and stainless-steel versions. The B-flex series provides lateral flexibility, making it ideal for curves with tight radii, while maintaining product stability.

2. Bellt Modular Belts
Composed of interlocking plastic modules, modular belts are suitable for straight or curved layouts. They allow for width and pitch variations, simple maintenance, quick replacement, and great adaptability for different products.

Straight or Curved? The First Filter
All Bellt modular and conveyor belts can be used in straight lines. However, when curves are required, it’s essential to choose belts with lateral flexibility. This is especially important in “S” curves or systems with automated return. The B-flex series and articulated modular belts are ideal for such configurations.

The Importance of Pitch
Pitch is one of the most critical variables in conveyor design. It affects the sprocket size, smoothness of movement, and precision of transfers.

Smaller pitches reduce vibration and noise and allow for shorter, more precise transfers — ideal for small or unstable products. Larger pitches provide greater structural strength, impact resistance, and durability. In practice, the pitch must balance precision, longevity, and product requirements.

Top Surface: Where the Product Travels
The top surface of the conveyor belt impacts stability, grip, and ease of cleaning. Bellt offers a variety of surface types:

Closed surface
Open surface (perforated)
Textured or high-friction surface
Flights and optional accessories
The right choice depends on the product packaging, fragility, and process conditions.

Bottom Surface: Support, Cleaning, and Friction
Often overlooked, the bottom surface of the conveyor belt is key to system efficiency. It affects sliding friction, wear, lubrication needs, and cleaning performance.

Belts with optimized bottom surfaces glide more smoothly, reduce energy consumption, and lower system temperature — resulting in less wear, less noise, and lower maintenance.

Conclusion
Understanding the differences between conveyor belts, surfaces, and pitch options is essential for properly specifying an industrial transport system. Bellt Correntes provides complete and customized solutions to meet the technical and operational needs of each industry.
