Trough Belt Conveyor: Detailed Structure & Applications

If the production line is the lifeblood of a business, then the trough belt conveyor is the resilient heart, pumping vitality into every operation. Conveyors not only optimize every process but are also the key to improving labor productivity and minimizing costs. Naltako invites you to explore this special conveyor line and the reasons why it has become the top choice for businesses.

What is a trough belt conveyor?

Trough belt conveyors are a specialized conveyor system designed specifically to transport bulk materials in granular, powder, or small block forms. The biggest difference compared to standard flat conveyors lies in its characteristic trough-like shape. This shape is created by the arrangement and tilt angle of the conveyor support rollers, helping to form a deep concave trough that embraces and firmly holds the material during movement, preventing spillage and material loss so it can be moved to the hydraulic lift table efficiently.

Structure of the trough belt conveyor

The structure of the trough belt conveyor is a perfect combination of mechanical parts and high load-bearing materials, creating a smooth and powerful operating system:

Conveyor belt

This is the core component, usually made of synthetic rubber or natural rubber, capable of resisting abrasion, heat, and impact well. The core of the conveyor belt is often reinforced with layers of fabric (polyester, nylon) or steel cables, helping to increase tensile strength and load-bearing capacity.

Roller system

The key point creating the trough shape is the support roller system. Typically, a roller assembly will consist of a horizontal middle roller and two side rollers tilted at an angle (usually 20°, 35°, or 45°). This arrangement not only defines the trough but also helps distribute the load evenly on the conveyor belt.

Conveyor frame

The load-bearing frame is made of sturdy steel, serving as the base for the entire system. The frame is designed in modules for easy installation, expansion, or length modification.

Motor and transmission system

The electric motor and gearbox provide strong traction, keeping the conveyor belt moving continuously. This system ensures the conveyor operates stably even with heavy loads or steep gradients.

Applications of trough belt conveyors

Thanks to the special structure and superior advantages, trough belt conveyors have become indispensable “sentinels” in many industries:

• Mining and mineral processing industry: Trough conveyors are used to transport coal, ore, stone, sand, gravel… from mining sites to processing plants, or from storage warehouses to gathering areas.
• Cement and construction material production: Transporting clinker, cement, sand, crushed stone, helping the production process take place continuously without interruption.
• Energy industry: Supporting thermal power plants in transporting coal, ensuring a stable fuel source for electricity production.
• Agriculture and food industry: Transporting grain, bran, animal feed, sugar, salt… in processing plants.
• Chemical production: Used to transport powder and granular chemicals, ensuring safety and hygiene.
