How it works?
Two hoppers are arranged vertically in this sysytem. The upper hopper discharges the raw materials to the lower hopper whose job is to measure and record the weight of the raw material that is sent by the upper hopper. Once the measured weight reaches a pre-defined value, the indicator will command the upper hopper to stop the discharge, wait until the weight stabalises and roundd up the batch. The indicator then commands the upper hopper to continue with the discharge for the next cycle.
