Abstract
An apparatus for separating a slurry into phases containing larger and smaller grains has an upright tank in which a plurality of downwardly extending inlet pipes open at their lower ends between outlets for the coarse and fine phases located at the bottom and top of the tank, respectively. At the lower end of each inlet pipe, an upwardly widening frustoconical cup is provided with a bottom confronting the open end of the inlet pipe to deflect the slurry upwardly and outwardly. Within the cup swirl vanes impart a swirl to the slurry.
