Foam bitumen module
By mixing hot bitumen with water in the foam bitumen module, the bitumen is foamed to many times ofits original volume. This means that a large surface not only lowers the viscosity, but also improves the wettability of the aggregate material.
For the technical implementation, the weighing and mixing section simply has to be expanded with theFOAM BITUMEN MODULEwhich is additionally flanged onto the mixer cabinet and the bitumen weigh hopper.
Uncomplicated connection usingPLUG & WORKensures fastinstallation and commissioning.
In order to add smaller amounts of solid additives, BENNINGHOVEN offers the technical solution of thepowder/granulate feed system. Depending on the material and added quantities, additives can be dosed into the mixer with a stream of air. Themulti-variable feedis another option. This patented technology features precise dosing (exact weighing system) and allows larger additive quantities to be added to the mixer. The materials are fed with an elevator or inclined conveyor.
With theadhesive system,up to two liquid additives can be added to the process. The system is equipped with two conveying pumps which dose the liquid additives into the bitumen weigh hopper and/or into the mixer. The system has a very good resistance to chemicals and high temperatures.
