Counter Flow Drum Mix Plant
(60-120 TPH)
SALIENT FEATURES
- ‘THERMIX’ DRUM allows RAP* addition of upto 30% directly into the mixing zone by the help of RAP Collar attached to ‘THERMIX’ DRUM.
- Alltech’s high efficiency ‘THERMIX’ DRUM is equipped with modulating long nose burner. ‘THRMIX’ DRUM gives high fuel efficiency with low emission.
- ‘THERMIX’ DRUM heats up the aggregate in heating zone as well as allows the mixing of aggregates with bitumen in a separate mixing zone to provide homogenous mixing.

| Advantage | Old Drum Mix Plant | Counter Flow Drum Mix Plant | Benefits |
| Technology | Old technology in which heating and mixing occurs at same place. | New technology in which mixing zone and heating zone are at different places in same drum. | Viscosity of bitumen as well as properties of mixed aggregate doesn’t get affected. |
| Recycled Material | Facility to add RAC is not available | RAC can be added upto 30% | Recycled material can be used |
| Filler | Filler cannot be added | Filler can be added directly into mixing zone via RAP Collar | Filler material can be used to produce homogenous mix |
| Pollution | Only Venturi Type Dust Collector is provided for pollution control which requires large area for Dust Collection | Pollution Control Bag House is provided which ensures pollution free operation of plant | Pollution Free plant |
| Hot mix quality | Hot mix quality gets deteriorated since mixing and heating occurs at same place | Homogenous Mixing since mixing zone and heating zone are separate | Gets Homogenous mix |
| Dryer Drum | Parallel flow heat transfer which deteriorates the properties of mix as well as bitumen | Counter Flow heat transfer with mixing zone behind the burner and attached RAP Collar provides homogenous mix | Filler, RAP can be added and mixing takes place behind the burner flame |
| Fuel Consumption | Consumption of Fuel is more | Consumes less fuel as compared to drum mix plant | Less Fuel Consumption leads to cost saving of fuel |
