The quantitative sidewall belt feeder is a high-tech equipment integrating conveying, weigh-metering, and quantitative control. Engineered to adapt to various harsh production environments, it provides continuous feeding and accurate metering for various lumpy and granular materials (such as limestone, iron powder, and clay) as well as powder materials (such as fly ash and cement), supplying precise data support for industrial production control and management. Featuring an integrated weigh frame design, materials drop onto the feeding section at the tail and pass through the weighing section as the belt runs. The load cells and speed sensors detect the instantaneous material weight and running speed respectively, transmitting the data to the weighing controller. The controller processes the data to calculate the instantaneous flow rate and outputs a PID control signal via software algorithms. Through variable frequency adjustment, it regulates the speed of the feeding device or batching scale to ensure the material flow rate precisely matches the preset requirements.
Combines conveying, weigh-metering, and quantitative control functions to achieve continuous feeding, high-precision metering, and automated regulation, providing highly accurate data support for industrial production workflows.
Utilizes a robust, integrated weigh frame structure paired with dual-detection from load cells and speed sensors. It delivers a dynamic metering accuracy superior to 1.0%, a static metering accuracy superior to 0.5%, and up to 0.125% for high-precision models.
The weighing controller processes instantaneous weight and speed data in real time to output PID control signals. Through variable frequency drive (VFD) adjustment, it modulates the rotation speed of the feeding equipment or batching scale, ensuring the material flow rate meets preset targets with pinpoint accuracy.
Equipped with a complete assembly package, including the weigh frame, belt, VFD, belt trainer (aligner), speed sensor, load cells, motor-gearbox unit, control cabinet, signal cables, drive/driven drums, idlers, and internal/external belt scrapers (cleaners).
