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.

The basic machine comprises:

A filter less centrifuge to separate the filler from the solvent and bitumen solution.

A solvent recovery unit to recover the solvent.

A sieving unit with solvent spraying nozzle to separate and wash out the asphalt sample capacity 7 sieves 200 mm dia.

The apparatus is supplied complete with separate electric control panel and three spare cups for the extraction centrifuge.
