Type of Asphalt Concrete Plant
Exactly, the asphalt concrete plant is the alias of the asphalt production plant. Usually, we call it asphalt mixing plant for simple. The asphalt concrete mixing plant is also used to blend aggregate, asphalt and mineral filler under increasing temperature in a certain proportion. The combination of materials is mixed into homogeneous asphalt mixture.
Asphalt mixer plant can be divided into various types according to different standards. For instance, in terms of mixing modes, there are DHB drum continuous type and batch type; it is generally divided into LB series tationary type and YLB series mobile type for the transport method; small, medium and large types are partition in production capacity.
