Equipped with a high-precision weighing sensor module, this unit operates on the loss-in-weight principle. The control system continuously measures weight differences in the silo over time to calculate real-time flow rates and automatically adjusts discharge speed to match set ratios. It triggers automatic refilling at low levels while maintaining a constant discharge rate during refilling. An integrated arch-breaking mechanism prevents powder bridging and clogging. With a compact design, smooth operation, and low energy consumption, the system ensures dynamic precision throughout the process, guaranteeing consistent formula stability.
