Abstract
The present separation apparatus makes it possible at low cost continuously to separate a mixture according to the density of its constituent particles which have been graded to an upper limit of the particle size of any shape, and is particularly suitable for the separation of electrical storage battery waste. A separation medium, consisting preferably of a liquid and a gaseous flow medium, fed into a vertical separator column (1) via a mixing nozzle (10) flows through the column from the bottom upwardly. Above a constriction (7) adjacent a through-flow aperture (9) there is a baffle (15) which is movable transversely relative to the longitudinal axis (4) of separator column (1) to form a flow channel (20) leading to the through-flow aperture (9). The width of the flow channel (20) when the baffle (15) lies against the internal wall (1a) of the separator column (1) is just sufficiently large to let the particles through. The high flow velocity of the separating medium in the flow channel (20) as well as its continuous changes in shape caused by the baffle (15) result in an efficient separation of the mixture fed into the column through an upper, eccentrically arranged inlet opening (6). The heavy fraction (3) sinks into a lower collecting vessel (2) and the light fraction is discharged together with the outflowing separation medium through an upper outlet aperture (21).
