Dewatering method and device-rinse solid granular materials rich filiform particles (i.e., metal wires)

摘要

Wringer and occasionally rinse rich solid granular material filiform particles (6) and loaded with fine particles, comprising: - a first vibrating sieve (1) comprising a perforated plate (2) with holes (9), comprising a transverse median (X), said perforated plate (2) an inclination (α) of between 1 and 10 ° to the horizontal plane passing through said transverse median (X), a head portion (3) and a tail portion (4) being located said head portion (3) below said horizontal plane of said first vibrating sieve (1) and said tail portion (4) first sieve being positioned above said horizontal plane of said vibrant (1), - a feed (5) of said rich solid granular material filiform particles (6) and loaded with fine particles established for feeding said rich solid granular material filiform particles (6) on the head portion (3) dich or first vibrating sieve (1), - at least one feed of an aqueous phase (7) to remove by dragging said fine particles, - an output of said rich solid granular material filiform particles (6) drained established for recovery ( 14) of said rich solid granular material filiform particles (6) in said tail portion (4), and - an output of said aqueous phase charged fine particles by gravity, under said first vibrating sieve (1), characterized in that said perforated (2) with holes (9) plate has projections (8) directed from the face of said perforated plate (2) receiving said rich solid granular material filiform particles (6) upwards, said projections (8) being provided each of at least one orifice (9).
