Embodiment Construction
[0016] Such as figure 1 As shown, the process flow of the cold aggregate batching system of the existing widely used continuous asphalt concrete mixing plant is inside the dotted line box. Aggregate is loaded from the well-graded stockpile area to several "cold aggregate batching bins", and batched through each batching device (assuming that 4 specifications of aggregates are used for batching). The metering method of the batching process Usually, the "volume method" is adopted, that is, the cold aggregates of four specifications are sent to a collection belt conveyor after batching, and then the total weight of several kinds of aggregates flowing per unit time is measured by a "belt electronic scale". The detection is used as the basis for proportion control in the future asphalt metering and mineral powder metering. figure 1 The batching process is: multiple cold aggregate batching bins-continuous measurement of cold aggregate (to measure the total amount of aggregate).
