Filterless Centrifuge Binder Extractors Asphalt | Burgan UAE

Filterless Centrifuge Binder Extractors are used for rapid filterless separation of filler from binder solution coming from wire mesh extractors or solvent extraction systems, available across UAE and GCC through Burgan Equipment Co. Developed by Controls SPA, the filterless method assures complete filler recovery without the need for filter discs, reducing consumable costs and improving extraction efficiency.

Overview

The Filterless Centrifuge Binder Extractors by Controls SPA can also be used for binder recovery from an asphalt sample previously disintegrated in solvent and poured into the funnel fitted with 200mm diameter test sieves to separate aggregates gradually. The solvent used during the extraction process can be profitably recovered using a solvent recovery unit, reducing operating costs and environmental impact.

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 while the liquid is discharged outside through the outlet tubing.

Filterless Centrifuge Binder Extractors — Key Performance Features

  • High-Speed Filterless Operation: The Filterless Centrifuge Binder Extractors operate at a maximum speed of 11,000 rpm, providing powerful centrifugal force for complete and rapid filler separation without the need for filter discs. This eliminates the ongoing cost and replacement hassle of filter discs used in conventional centrifuge extractors.

  • Automatic Speed Ramp Control: A special electronic circuit provides a preset controlled ramp that gradually increases speed to the maximum, preventing sudden mechanical stress and ensuring smooth, safe operation throughout every extraction cycle.

  • Two Capacity Models: The Filterless Centrifuge Binder Extractors are available in two models to suit different laboratory requirements. The 75-B0024/P model features a 70mm diameter cup for filler extraction up to 100g per test, while the 75-B0024/B model features a 122mm diameter cup for filler extraction up to 400g per test.

  • Continuous Flow Design: The continuous flow design allows solvent to be poured continuously from the top funnel during operation, maximizing extraction efficiency and reducing total test time compared to batch extraction methods.

  • Complete Filler Recovery: The filterless centrifugal method ensures complete recovery of filler material from the binder solution, providing accurate and repeatable results for asphalt mix composition analysis in compliance with ASTM D2172 and EN 12697-1.
