The counter flow series of double drum asphalt mixers offer a compact design to contractors with production range as low as 40 tph to as high as 120 tph. Plants above 120 tph are available and are custom made. These plants are designed to give better mixing quality compared to the single drum parallel flow plants offered.

Due to separate drying drum, these plants boast of long aggregate drying time. The same holds true for mixing also because of a separate mixing unit with this equipment. Due to separate drying and mixing zones it is very easy to achieve maximum level of heat transfer and fuel efficiency which is not possible with parallelflow plants.

The dust is sucked by the exhauster as soon as the aggregates enter the drying drum. This dust is treated by primary and secondary pollution control units. Dust free aggregates move from one end of the drum to the other end. During their transit, each aggregate is uniformly treated to heat by the burner present on the opposite side of the drum. Since the burner of counter flow asphalt mixer is on the opposite side of the flow of aggregates, this design is called as counter flow. This design ensures that by the time aggregates move towards the other end of the drum, they are moving closer to the burner and hence the burner will require lesser efforts to heat the aggregates compared to the parallel flow hot mix asphalt plants.


The other drum is for mixing of aggregates with bitumen and other minerals or additives. The second drum receives hot aggregates where they are uniformly mixed with bitumen and minerals / additives. Bitumen and other minerals are conveyed to the second drum by means of a pipe. The exit of hot asphalt is directly on a heat resistant belt leading to small hopper or a silo before discharge into the truck.


burner for asphalt plant

Burner supplied with the double drum asphalt mixing plant is multi fuel type as it is capable to work with diesel and LDO. The burner can also be equipped with accessories to make it suitable for FO. The burner is low noise and fuel efficient machine designed for long term use and to give smooth operation.
