Apparatus for separating solids of different shapes

摘要

Apparatus for separating spherically-shaped solids from irregularly-shaped solids comprising a rotatable separating table having a frustoconically shaped upper surface, the angle of inclination of the upper surface with the horizontal being such that spherically-shaped solids supplied onto the upper surface will roll down towards a central vertical conduit at the lower end of the upper surface and irregularly-shaped solids supplied onto the upper surface remain at rest. The apparatus further includes a number of supply structures for the supplying of a mixture of spherically-shaped solids and irregularly-shaped solids onto the upper surface and removal means for removing irregularly-shaped solids from the upper surface.
