COUNTERMIX 90-120

  • Photos

The CounterMix 90-120 counterflow continuous drum mix plant provides efficiency, production and high use of recyclables.

Conventional continuous mixing plants utilise parallel flow, where the material to be heated and the hot gases flow in the same direction. In a counterflow dryer drum, the material to be heated and the hot gases flow toward each other, or in opposite directions.

The counterflow process is highly efficient because it maximises the transfer of heat from hot gases as well as radiation heat from the burner flame. In addition, the spraying of bitumen and filler is done when the hot aggregates pass behind the burner in the same dryer drum.
