Drive belt pulleys - Import export

Belt conveyors used for handling bulk solids utilize rubber-covered belts, where the inner carcass of the belt provides the necessary strength to pull and support the conveyed load. The carcass is shielded from damage by layers of rubber, which may vary in thickness depending on the specific application. Belt conveyors exhibit the capability to transport materials across a broad range of rates, spanning from just a few kilograms per minute to several thousand metric tons per hour. ndard troughing angles are commonly set at 0°, 20°, 35°, and 45°. The angle of surcharge is a material-specific property and can be compared to the dynamic angle of repose. The power requirements for belt conveyors hinge on various variables, including the conveyor’s profile, the type of drive-pulley arrangement, belt tensions, belt speed, and idler spacing.

In a belt conveyor system, pulleys play a crucial role by altering the direction of the belt in a vertical plane. They create a continuous loop for uninterrupted operation. The pulley, also referred to as a drum, and its accompanying shaft combine to create a unified structure. Their operational features are interdependent. The evolution of conveyor pulley construction has advanced from fabricated wood to cast iron and, currently, steel fabrication. Pulleys are produced in various sizes, with the standard steel pulley being the most widely employed in conveyor systems.
