Asphalt Counter Flow Drum Mix Plant
THERMIX DRUM
RAP up to 30%
- THERMIX DRUM heats the aggregate in the heating zone as well as allowing homogenous mixing with the bitumen (asphalt) in a separate mixing zone.
- Aaspa high-efficiency ‘THERMIX BRUM Long Nose Burner’ is equipped with the facility that delivers high fuel efficiency with low emissions.
- The RAP collar attached to the ‘THERMIX’ DRUM can directly incorporate up to 30% of the RAP into the mixing zone.
- The ‘THERMIX’ DRUM allows the re-incorporation of ingredients into the mixing zone.

Why Should be used Counter Flow Drum mix Plant in Comparison To Drum Mix Plant?
| Sr. No | Old Drum Mix Plant | Counter Flow Drum Mix Plant | Benefits | |
| 1 | Technology | Old technology in which heating and mixing takes place in one place. | New technology in which mixing zone and heating zone are at different places in the same drum. | Homogenous mix is a |
| 2 | Recycled Materials | RAC blending facility is not available. | Up to 30% RAC can be mixed | Recycled material can be used. |
| 3 | Filler | Filler mixing facility is not available. | Filler directly through the RAP caller. Can be mixed in the mixing zone. | Filler material can be used to produce homogenous mix |
| 4 | Pollution | For pollution control only Venturi type dust collector is provided. Which requires a large area. | Pollution control bag house is provided which ensures pollution free operation of the plant. | pollution free plant |
| 5 | Hot mix quality | The quality of hot mix deteriorates. Because mixing and heating take place at the same place. | Homogenous mixing fafar zone and heating zone are separate. | Homogenous mixing fafar zone and heating zone are separate. |
| 6 | Dryer Drum | Parallel flow heat transfer t deteriorates the properties of the mixture as well as the bitumen (asphalt). | Counter Flow Heat Transfer is behind the firmit mixing zone burner. Homogenous mix is obtained. | Low fuel consumption saves fuel. |
| 7 | Fuel Consumption | Fuel consumption is high. | Consumes less fuel as compared to imix plot. | Low fuel consumption saves fuel. |

High Fuel Efficient Modulating Long Nose Burner Suitable For Diesel / LDO / FO
High quality and reliable electric and electronic components are used inside the control room. which are easily available all over the world.
Highly Efficient Reverse Air Flow Cleaning Bag house Filter With Cascading Type Primary Dust Collector Primary East Collector ensure dust collected before bag filter and re-entered dust collected in WE.
Venturi Type Wet Dust Collecting Unit
The CV Series is a ventory type high efficiency wet dust collector that maintains the required environmental standards in specific areas. Wet collectors include ventory scrubbers and cyclonic or centrifugal-type scrubbers that operate on different principles than the previously described dry cartridge collectors.
RAC Retrofit
Directly using a RAP caller connected to ‘THERMIX DRUM’ Up to 30% of RAP can be used.
