The belt scale consists of four main components: weighing frame, weighing module, speed sensor and display meter. The weighing bridge is mounted on the conveyor frame. When the material passes through, the weight of the material on the belt conveyor detected by the metering rollers acts on the load cell through a lever to produce a voltage signal that is proportional to the belt load. In the belt scale there is a load cell mounted on the weighing bridge, when working, the weight of the material detected on the belt into the weighing instrument, at the same time by the speed sensor belt conveyor speed signal is also sent to the weighing instrument, the instrument will be the speed signal and the weighing signal for integral processing, to get the instantaneous flow and the cumulative amount. The speed sensor is directly connected to the large diameter speed roller, providing a series of pulses, each pulse represents a belt movement unit, the frequency of the pulse is proportional to the belt speed. The weighing instrument receives signals from the load cell and the speed sensor, and through integration operations derives an instantaneous flow value and a cumulative weight value, which are displayed separately.

The belt scale utilizes a high-precision bin Weighing system for real-time detection of the weight of the loaded bin. Equipped with a real-time automatic control system for receiving and processing the input signals, including bin weight detection, bin feed flow detection, compartment number, compartment tare, compartment position and compartment gross weight, and automatic control and adjustment of each compartment's charging weight. The user-friendly HMI interface allows easy and intuitive management and monitoring of the whole loading system. The content of the man-machine interface can be specially customized according to the user's requirements.

The belt weigher is used for the quantitative feeding of bulk materials, the feeding process is a continuous feeding of the belt, the Feeder will come from the user feed silo or other feeding equipment to transport the material and through the weighing bridge for weight detection, at the same time mounted in the tail wheel of the speed sensor on the belt for speed detection. The measured weight and speed signals are sent to the accumulator for differential processing and display the instantaneous flow in tons per hour for comparison, and according to the size of the deviation from the output of the corresponding signal value (PID signal), through the frequency converter to change the speed of the motor to change the feeding volume, so that it is a certain amount of time with the set value, so as to complete the control of a constant feeding flow.
