?What is a conveyor belt

A conveyor belt is a mechanical device used to transport materials from one location to another within a controlled path. It typically consists of a continuous belt made of rubber, metal, or fabric that is looped around two or more pulleys. One or more of these pulleys are powered by motors, which move the belt and the materials placed on it. Conveyor belts are integral to various industries and are used for transporting a wide range of products, from lightweight items like packages to heavy bulk materials such as rocks and minerals.

How Conveyor Belts Work

Conveyor belts function by creating a frictional force between the belt and the drive pulley. As the drive pulley rotates, it pulls the belt forward, allowing materials to move along the belt’s surface. Depending on the type and configuration, conveyor belts can move materials horizontally, inclined, or even vertically.
