An overland belt conveyor is an essential system used in many industries for transporting bulk materials over long distances. These conveyors are crucial in industries like mining, quarrying, cement production, and aggregate handling, where the need to move large volumes of material efficiently, over varying terrains and long distances, is paramount.
In this article, we will explore what overland belt conveyors are, how they work, their key features, advantages, applications, design options, and maintenance requirements. By the end, you'll have a comprehensive understanding of why overland belt conveyors are indispensable in modern bulk material handling operations.
Overland belt conveyors operate on a simple but highly effective principle: they use a continuous belt system to transport materials across varying distances and terrains. The system consists of several key components, including belts, pulleys, motors, and idlers, which work together to move materials smoothly and efficiently.
Conveyor Belt: The belt is the main component, designed to transport materials. It can be made from various materials, such as rubber, PVC, or steel, depending on the material being transported.
Pulleys: Pulleys guide the belt and help maintain tension. They are typically located at the start, middle, and end of the conveyor to ensure the belt runs smoothly.
Idlers: These rollers support the conveyor belt along its length and ensure it runs properly by providing the necessary support and tension.
Motors and Drives: Motors are used to power the conveyor, while the drives control the speed and movement of the belt.
Conveyor Frames: The frames hold all the components in place and support the structure of the conveyor.
The conveyor belt moves continuously over pulleys and idlers, carrying materials from one point to another. Material is fed onto the belt at the beginning of the conveyor system, and gravity, combined with the continuous movement of the belt, allows the materials to be transported over long distances. As the belt moves, the material is carried along and discharged at the other end of the system.
