PRIMACH WARM MIX FOAMING DEVICE
Foaming bitumen system is consisted of foaming unite, water dosing and supply unit,water replenishing unit, and controlling system. It has lots of the advantages compare with the normal mix bitumen. Foaming bitumen can be used under thetemperature 50-60°that much lower than the hot mix bitumen, Which can reduce the projectcost and pollution emission. Feed the foaming medium (water or vapour) into the high temperature liquid bitumen, the medium and the bitumen combine to the mist. The bitumen adhesion will be less and the volume will expand rapidly. This expansion is purely physical processed, the chemical property of the bitumen do not change.
Greatly reduce the hot mix temperature(30-50°)
