Drying, heating and metering of cold aggregate. Heating, insulation and metering of asphalt. According to the set mixing ratio, the raw materials such as hot aggregate and hot asphalt are mixed with a mixer to form an evenly mixed asphalt mixture that meets the quality standards. A certain amount of asphalt mixture can be stored if necessary. The production of asphalt batching plant includes multiple processes such as batching, drying, metering, mixing, and storage, etc. At the same time, the operation of the equipment requires a control system and various necessary parameter monitoring. A complete set of equipment includes a variety of mechanical and electrical devices. Basically, it can be said to be a highly automated factory integrating various technologies such as machinery, electrical automation, pneumatic or hydraulic pressure, and computers. The raw materials are aggregates, slag powder and asphalt of various specifications, and the products are asphalt mixtures that meet quality standards.
