Centrifuge binder extractors

Asfalto/miscele bituminose - Centrifuge binder extractors: Centrifuge binder extractors

The centrifuges are used for the determination of bitumen percentage in bituminous mixtures. All models comprise a removable precision-machined rotor bowl housed in a cylindrical aluminium box. They are driven by an electric motor fit with AC drive (inverter) with the double function of speed control up to...

Filterless centrifuge binder extractors

Asfalto/miscele bituminose - Filterless centrifuge binder extractors: Filterless centrifuge binder extractors

Used for rapid filterless separation of filler (ash) from binder solution coming, for instance, from \#wire-mesh-extractor\# model 75-B0015. The centrifuge can also be used for binder recovery from an asphalt sample previously disgregated in solvent and poured into the funnel fit with 200 mm dia. test sieves...

Reflux extractors

Asfalto/miscele bituminose - Hot methods binder extractors: Reflux extractors

Used for the quantitative determination of bitumen in hot-mixed paving mixtures and pavement samples. The bitumen content is calculated by difference from the weight of extracted aggregates, moisture content and ash from an aliquot par of the extract. The apparatus consists of a two wire mesh cones with...

Automatic bitumen extractor

Asfalto/miscele bituminose - Automatic binder extractor : Automatic bitumen extractor

Introduction Used for separation and extraction of bitumen by use of perchloroethylene  or trichloroethylene solvents and sieving, for the separation of filler by centrifuge action and for the recovery of solvent material. The complete cycle is carried out automatically. We propose two versions...

Hot mix asphalt automatic closed loop extractor PAVELAB50

Asfalto/miscele bituminose - Automatic binder extractor : Hot mix asphalt automatic closed loop extractor PAVELAB50

These tests methods are used for quantitative determinations of bitumen in hot-mixed paving mixtures and paving samples for specification acceptance, service evaluation, control and research. These methods prescribe the solvent or solvents that can be used for the binder extraction and recovery. The...
