Filterless Centrifuge Extractor
The Continuous-Flow Filterless Centrifuge Extractor is an American-made, high-performance instrument designed to accurately recover mineral filler fines from nonflammable solvents in asphalt mix extraction tests. By eliminating the need for filters, this extractor simplifies the analysis process and significantly improves accuracy, making it an essential tool for professionals in the asphalt testing industry.
How It Works
The solvent suspension is fed through the included top funnel into a special 526mL, 7x2.5in (178x64mm) HxID aluminum beaker that rotates at an impressive 11,000rpm. Under the high centrifugal force generated, the liquid moves up the beaker wall and exits through overflow tubing, while the solids remain in the beaker for easy removal. The continuous-flow design allows for uninterrupted feeding until the beaker's solids-retaining capacity is reached, making it ideal for high-volume testing environments.
Sieve Options
The extractor comes with full-height No.18 (1mm) and No.200 (75μm) stainless steel sieves that fit into the top of the inlet funnel. A No.230 (63μm) sieve can also be substituted for the No.200 sieve to suit specific testing requirements. When using the sieves, the extraction process is straightforward — pre-dissolve the mixed sample with solvent and pour it into the sieves.
Durable and Safe Design
The rotating spindle and electric motor are enclosed in a sturdy cast aluminum case, ensuring long-lasting durability and operator safety. The robust construction of this extractor ensures reliable performance even in demanding testing environments.
