Many belt conveyors are low-speed types with belts running in the range of 2-4 m/s that transport materials a short distance, up to 1 km. In contrast, some critical services now rely on conveyors with belt speeds exceeding 5 m/s. Modern technologies enable achieving speeds as high as 10 m/s, 12 m/s or even more.
