Continuous-Flow Filterless Centrifuge, American-made offers a simple, accurate way to recover mineral filler fines from nonflammable solvents in asphalt mix extraction tests. The analysis is simplified and accuracy is improved by eliminating the filter.
The solvent suspension is fed through the included top-funnel into an included special 526ml, 7x2.5in (178x64mm) HxI.D. aluminum beaker rotating at 11,000rpm. Under high centrifugal force, the liquid moves up the beaker wall and out through the overflow tubing while solids remain for easy removal. Continuous feeding is possible until the solids-retaining capacity of the beaker is reached.
Included full-height No. 18 (1mm) and No. 200 (75μm) stainless steel sieves fit into the top of the inlet funnel. A No. 230 (63μm) sieve may be substituted for the No. 200. When using the sieves, the extraction process can be run by pre-dissolving the mixed sample with solvent, then pouring it into the sieves.
The rotating spindle and an electric motor of the centrifuge are enclosed in a sturdy cast aluminum case. Two aluminum beakers and a No. 18 (1mm) and No. 200 (75μm) stainless steel sieves are included with each unit.
