Used to perform reliable analysis on bituminous mixtures utilizing the perchloroethylene (PCE) or tetra-chloroethylene solvent which is classified: R40 not cancer producing (see note*), for quantitative determination of binder or bitumen contained in pavement samples and hot mixed mixtures.
The system performs in only one complete automatic cycle:
- the washing, disaggregation and separation of the bitumi-nous mixture;
- the separation of the filler from the solution formed by solvent, bitumen and filler;
- the recovery and distillation of solvent material allow-ing a further utilization.
This unit, in a short time, performs out a serie of analysis that normally require a long time and labour, by reducing extraction costs.
The unit comprises:
- An electromagnetic sieving unit, insuring high quality double vibrating action (vertical/rota-tional), with solvent spraying cover for washing and disaggregation of the sample.
- A continuous flow filterless centrifuge having rotation speed of 11000 rpm equipped with a stainless steel beaker dia. 120 mm., filler capacity appr
