Abstract
Various embodiments provide a high precision belt weighing device and a high precision belt weighing method. An exemplary high precision belt weighing device includes a set of buffer carrier rollers provided between a first and second belt weighing scale frames. A volume scale hopper is provided above the set of buffer carrier rollers. A transfer conveyor is provided above the volume scale hopper. The first and second belt weighing scale frames, the volume scale hopper, an initial point detector, and a speedometer are connected with a weighing control instrument by cables. Cumulative weights of bulk materials handled by each of the first and second belt weighing scale frames, the corrected weight of bulk materials in the volume scale hopper, and a zero point in the length of a conveying belt detected by the initial point detector are displayed on the weighing control instrument.
