 Aggregate metering system:

There are two forms, accumulative weighing and single weighing.

Accumulative metering is to add various materials one by one into the same hopper for superimposed metering. It has a simple structure and low manufacturing cost, but it is prone to errors, especially when the metering value is small;

Single metering is to put each material in its own hopper for metering. After metering, it is concentrated in a general hopper and then added to the concrete mixing plant equipment. The metering accuracy is high and the cost is relatively high.
