BAC SEDIMENTATION [3 records]

Record 1 2016-03-07

English

Subject field(s)
  • Mineral Processing (Metallurgy)
  • Processing of Mineral Products
DEF

A classifier for separating fine-size solids from coarser solids in a wet pulp consisting of an interrupted-flight screw conveyor, operating in an inclined trough.

CONT

Spiral classifiers ... do not normally set up a turbulent stirring action in the classifying pool, but cross-pieces can be bolted to the spiral shoes to produce this. ... As settled sands emerge from the "V" end of the pool, they bring with them some trapped or "drag-out" slime which should properly have overflowed at the weir. Washing sprays are often used to return this material to the pool. [The] spiral classifier ... carries its sands upward on the rising side of the helix, so that sprays can be used at any point and there is a good channel for running their washed product straight down to the pool.

Domaine(s)
  • Minéralurgie (Métallurgie)
  • Préparation des produits miniers
DEF

Classificateur hydraulique dans lequel les sables sont remontés et extraits de l’appareil à l’aide d’une vis de transport.

CONT

Classificateurs à drainage mécanique. Le classificateur à vis utilise la partie inférieure du bac élargie avec débordement pour constituer une zone de sédimentation sans turbulence, dite «pool de classification». [...] Les particules décantées sont brassées par la partie de la spirale plongeant dans le pool de classification avec élimination des indésirables évacuées par le seuil de débordement; puis elles sont entraînées vers le haut en subissant un essorage jusqu'à la sortie supérieure.

Record 3 1980-10-06

English

Subject field(s)
  • Processing of Mineral Products
  • Mineral Processing (Metallurgy)
DEF

A shallow bowl with a concave bottom so that a liquid-solid suspension can be fed to the center; coarse particles fall to the bottom, where they are raked to a central discharge point, and liquid and fine particles overflow the edges and are collected.

CONT

The bowl classifier was developed to provide more pool area necessary for fine separations consistent with high tonnage.

French

Domaine(s)
  • Préparation des produits miniers
  • Minéralurgie (Métallurgie)
DEF

(...) classificateur à râteau dont le bac de sédimentation lente est très grand et agité par un système rotatif lent. L'alimentation se fait dans ce bac. Cet alimentateur est très précis en raison de la surface du bac.
