systems Manual:

The aggregate silo is loaded by a loader or a loading belt conveyor. The lower part of the aggregate bin is provided with an arc door feeder, which is opened and closed by the cylinder, and is combined with the centralized control of the microcomputer. When the compounding is started, the arc door opens the feeding material, and the precise compounding can be achieved. A horizontal belt conveyor is arranged under the weighing bucket, and four sensors are suspended on the belt, and the belt conveyor, the weighing bucket and various aggregates are sequentially accumulated for weighing. Aggregate weighing and discharging is controlled by PLC to ensure accuracy. The tare weight overweight microcomputer can automatically alarm, and the tare weight is automatically weighed again. After the aggregate is finished, it is sent to the lifting bucket by the belt conveyor. The lifting bucket rises along the track and the aggregate is discharged into the mixer.
