Full definition
The linear velocity at which a conveyor belt travels, measured in meters per second (m/s) or feet per minute (ft/min). Typical range: 0.5 m/s (light-duty in-plant) to 6 m/s (high-capacity mining overland), with some high-speed systems reaching 8-10 m/s. Belt speed, combined with belt width and trough cross-section area, determines the volumetric conveying capacity: Q (m³/h) = 3,600 × A × v, where A is the material cross-section on the belt. Higher speed allows narrower belts for the same tonnage, reducing idler and structure costs, but increases belt wear, dust generation, transition distance requirements, and material trajectory issues at discharge. Lower speed reduces wear but requires wider belt. Speed selection trade-offs per CEMA 7th Edition and DIN 22101: consider material characteristics (friable materials need lower speed), loading method, transfer height, belt life, and dust control. Variable-speed drives (VFDs) allow speed adjustment for changing tonnage, optimizing energy consumption.
