Working principle:
The middle conical bucket is a metering bucket. When the metering bucket is zero, the output circuit of the control instrument is closed, and the upper bin switch is opened to start feeding. When the weight of the material in the measuring hopper reaches the set value, the output signal of the instrument is controlled to close the hopper and the stirring motor starts to stir. The stirrer of the metering bucket stops working when the set stirring time is reached, and the lower mouth of the metering bucket opens, and the stirred material enters the lower bin. When the weight of the metering hopper is zero, the process starts again.
The material level of the lower warehouse has a weight signal showing the remaining% of the cabin. And set the minimum line. When the bunker reaches the lowest line, the metering hopper can start working feed.
