A METHOD AND A MIXING STATION FOR MIXING OF BULK SOLID MATERIALS WITH BROAD PARTICLE SIZE DISTRIBUTION

A method and a station for mixing bulk solid material, in particular for mixing at least two materials (A, B) where at least one of these materials (A) has a broad particle size distribution. The material (A) is homogenized in a first mixer (5a, 5b) before being mixed together with material (B) in a...

Beschreibung
Zusammenfassung:	A method and a station for mixing bulk solid material, in particular for mixing at least two materials (A, B) where at least one of these materials (A) has a broad particle size distribution. The material (A) is homogenized in a first mixer (5a, 5b) before being mixed together with material (B) in a second mixer (7). The material (A) is homogenized in a gravimetric mixer (5a, 5b) with plural chambers and which is discharged in accordance to the mass flow principle. The materials (A) and (B) are preferably mixed in a gravimetric mixer (7) with plural chambers and is further discharged in accordance to the mass flow principle. The material (A) is substantially crushed bath material. The material (B) is primary and/or secondary alumina that mixed with (A) will be used as recycled anode cover material (ACM).
