  • High precision weighing array system for weighing dispersed material in motion on a conveyor belt assembly
    Patent number: 8829366
    Abstract: A belt weighing array system for dispersed material in a transportation process of measurement is mainly composed of a weighing sensor (12), a bearing beam (11), a supporting roller holder (10), and weighing supporting rollers (3). On both ends of the supporting roller holder (10) formed by at least two parallel arms, the weighing supporting rollers (3) are supported respectively, and the middle part of the supporting roller holder (10) is fastened with the bearing beam (11) across both sides, which is connected to a force transfer unit of the weighing sensor (12) fixedly. The sensor belongs to single type weighing sensor, and its base is arranged fixedly on a frame of a belt transporter by both sides.
