Belt conveyors, also known as belt-type conveyors or rubber belt conveyors, are a widely used type of conveying equipment. Various forms of belt conveyors can be found in conveying lines across almost all industries. Belt conveyors operate based on the principle of friction and are mainly used for the continuous transportation of materials. In the material conveying processes across various industries, belt conveyors serve as a transitional link between different stages; they are also important auxiliary equipment in production lines. Therefore, how to correctly select a belt conveyor is of great importance. 1. It is necessary to clarify factors such as the industries for which the belt conveyor is intended, the material of the conveyor belt, and the technical parameters of the belt width. For example, the rubber belt is suitable for operating environments where the temperature ranges from -15 to 40°C, with the material temperature not exceeding 50°C ； Plastic tapes have advantages such as oil, acid, and alkali resistance; however, they have poor adaptability to climate conditions, and are prone to slipping and aging. 2. The belt speed of the belt conveyor must be selected correctly. For longer horizontal conveyors, a higher belt speed should be selected ； The greater the inclination angle of the conveyor and the shorter the conveying distance, the lower the belt speed should be. For example: when the conveying volume is large and the conveyor belt is relatively wide, a higher belt speed should be selected ； For materials that are prone to rolling, have large particle sizes, exhibit strong abrasiveness, or tend to generate dust, as well as those requiring stringent hygiene conditions, a lower belt speed is recommended ； When using dump trucks, the belt speed should generally not exceed 2.5 m/s; when conveying fine or small-sized materials, a belt speed of up to 3.15 m/s is permissible ； When feeding or conveying materials with a high dust content, the belt speed can be set to 0.8–1 m/s; it may also be determined based on the characteristics of the material and process requirements. Belt conveyors can transport various materials and offer advantages such as cost-effectiveness, high throughput, good continuity, and stable operation. It can operate as a single unit to meet the client’s conveying process requirements, or it can transport materials over long distances in rugged and complex environments, thereby enabling automated and integrated production operations. It is now widely used in industries such as mining, coal, and power generation, serving as an ideal piece of equipment for long-distance, high-capacity, and continuous transportation.
