Device for separating a heterogeneous mass of solid material into fractions

摘要

A device for separating a heterogeneous mass of solid material into fractions. The constituents of a heterogeneous mass of solid material are comminuted and dried and then separated into fractions. The mass is received in a trough-shaped and subjected to vibration causing high density constituents to segregate downwards and low density constituents to segregate upwards, so that the fractions may be removed at different layer levels.
