Description
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 disaggregated in solvent and poured into the funnel fit with 200 mm dia. test sieves to separate gradually the aggregates. The test is carried out by pouring the solvent from the top funnel into the rotating aluminium cup. Due to the centrifugal effect, the liquid spreads on the wall and moves upwards, leaving mineral particles in the cup whilst the liquid is discharged outside through the outlet tubing. A special electronic circuit provides for a pre-set controlled ramp which gradually increases the speed to the maximum. Two models available: 75-B0024/N for filler extraction up to 100 g per test, fit with 70 mm dia. cup and 75-B0024/B for filler extraction up to 400 g per test, fit with 122 mm dia. cup. The 75-B0024/N, NY and NZ versions do not include sieves which have to be ordered separately, conforming to EN standard. See accessories. The cup should be internally lined with paper for a better and complete removal of filler. See accessories: 75-B0005/2.
The solvent used can be profitably recovered with the Solvent recovery unit.
