Conveyor belts consist of two end-pulleys and a continuous loop of material that rotates about them. They are used in a variety of material handing applications, including food and beverage processing, manufacturing, mining, packaging, and power transmission. Some conveyor belts are designed to transport commercial goods, construction materials, forest products, or pulp and paper. Others are designed for agricultural, general-purpose, or inclined conveying applications. Elevator belts are designed for vertical applications and have attachments such as buckets or trays. High-temperature conveyor belts are made of materials that are suitable for use at high ambient temperatures, or that are designed to handle high-temperature materials. Often, these products are used in oven conveyor belting and the conveyance of heat-treated parts.
