For DHB type drum asphalt mixing plant, the working flow as follows:

The mineral aggregate is loaded in the bunker of grading machine by loader machine, and the material is conveyed to drying cylinder from the load material belt after simply matching, then the material is heating and drying sufficiently by the fuel burning system, and mixed the asphalt to form uniform, heated mixture in drying cylinder, then the mixture get through the feed opening to inflow in the elevator.

And the mixture is promoted to hot storage bin. Then heating the flame of dry mineral aggregate, and the flame enter into the drying cylinder from the ignite opening, which is same to the mineral material forward direction.So it is called fair current type.

The asphalt (used to mix) is spewed in the drying cylinder by the effuser. The flame can be adjusted by controlling the fuel pump, then the drying degree and temperature high-low of mixture is adjustable.

The asphalt flowing rate can be adjusted by the speed regulating motor, then the adjust ratio of mixture is controllability.
