Filterless Centrifuge Binder Extractors
- EN 12697-1 | ASTM D2172
Filterless centrifuge binder extractors are 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 to separate gradually the aggregates.
75-B0024/B: Continuous flow filterless centrifuge 122 mm dia. cup. 380V, 50Hz, 3ph
75-B0024/N: Continuous flow filterless centrifuge 70mm dia. cup. Sieves not included. 230V/50Hz/1Ph
75-B0024/1: Aluminium beaker
75-B0005/2: Line paper for centrifuge cup. Pack of 100 pieces.
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 preset controlled ramp which gradually increases the speed to the maximum.
The cup should be internally lined with paper for a better and complete removal of filler. The solvent used can be profitably recovered with the solvent recovery unit.
