The HM-750R Continuous-Flow Filterless Centrifuge models offer a simple, accurate way to recover mineral filler fines from nonflammable solvents in asphalt mix extraction tests, no filter needed. Solvent suspension is fed through the included top funnel into a special 562ml, 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.
No. 18 (1mm) and No. 200 (75μm) stainless steel full-height sieves are included for fitting to the top of the inlet funnel if desired. 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 mix sample with solvent, then pouring into the sieves.
Rotating spindle and electric motor of the centrifuge are enclosed in a sturdy cast aluminum case. Two aluminum beakers are included with each unit.
