HYDROCYCLONE [10 records]

Record 1 2011-05-20

English

Subject field(s)
  • Tools and Equipment (Mechanics)
  • Equipment and Tools (Water Supply)
  • Water Treatment (Water Supply)
DEF

A desander [which is] operated ... by a fast-moving stream of fluid inside a special cone-shaped vessel ...

CONT

Hydrocyclones are used for sewage sludge degritting in applications requiring high efficiency and a high degree of grit removal.... [In] the hydrocyclone... the feed is introduced tangentially to a cylindrical feed section, and the liquid slurry develops a rotational movement and passes into a conical section. The centrifugal force created by the cyclonic movement of the liquid forces the heavier solid particles to the outer wall.

OBS

The terms "cyclone separator", "cyclone collector" and "cyclone" are often used as synonyms of "hydrocyclone". They are however generic with respect to "hydrocyclone" because whereas in hydrocyclones the solids are separated from a liquid, in the others the solids are separated from either a liquid or air mixture.

Key term(s)
  • cyclone separator
  • cyclone collector
  • cyclone
  • hydroclone

DEF

Séparateur de dessablage alimenté tangentiellement à une certaine pression, et dont le corps est incliné de telle sorte que le sable est évacué à l'aval et l'eau sale à l'amont.

DEF

A centrifugal device for removing sand from drilling fluid to prevent abrasion of the pumps.

OBS

A desander may be operated mechanically or by a fast-moving stream of fluid inside a special cone-shaped vessel, in which case it is sometimes called a hydrocyclone desilter.

Record 4 2001-02-27

English

Subject field(s)
  • Waste Management
  • Wastewater Treatment
CONT

When this [silt/sand] ratio is high, hydrocyclone separation is not appropriate and all the sediment must be dewatered or decontaminated.

French

Domaine(s)
  • Gestion des déchets
  • Traitement des eaux usées
CONT

Lorsque ce rapport [limon/sable] est élevé, l'hydrocyclonage n'est pas approprié et la totalité des sédiments est déshydratée ou décontaminée.

Record 5 2001-02-27

English

Subject field(s)
  • Dredging
  • Waste Management
CONT

... both routes start with hydrocyclone separation, which divides the sediment into two fractions : a fraction with a low contaminant content, the underflow, composed mainly of sand; and a second fraction in which contaminants are concentrated, the overflow or slime fraction, generally composed of fine-grain and organic material.

French

Domaine(s)
  • Dragage
  • Gestion des déchets
CONT

[...] la première étape des deux voies de traitement est la classification par hydrocyclone qui sépare les sédiments en deux fractions : la première avec un contenu faible en contaminants, la sousverse (fraction principalement composée de sable), alors que les contaminants sont concentrés dans la seconde fraction, la surverse; cette dernière, appelée aussi fraction vaseuse, est constituée généralement de grains fins et de matières organiques.

Subject field(s)
  • Processing of Mineral Products
  • Mineral Processing (Metallurgy)
  • Mining Equipment and Tools
OBS

Tri-Flo manufactures a hydrocyclone unit that efficiently removes sand and silt sized particles down to a 15 micron cut. The hydrocyclone units are complete with mud trough, manifold, 4" polyurethane hydrocyclones, pressure gauge, and all necessary connections.

Key term(s)
  • Tri-Flo

Domaine(s)
  • Préparation des produits miniers

  • Outillage et équipement (Exploitation minière)
CONT

Séparateur Tri-Flo [...] dérivé du [séparateur Dyna-Whirlpool] incorpore un second étage (simple ou double) de séparation, ce qui est avantageux lorsque l'alimentation est très variable; l'appareil délivre donc deux produits lourds, issus d'un double traitement à la même intensité ou de deux étapes à densité différentes, ce qui permet d'obtenir un concentré riche, un mixte et un stérile correctement épuré.

DEF

Tube projecting into central vortex of hydrocyclone, through which the classified fine fraction of pulp leaves the system.

CONT

The vortex finder is so adjusted as to project into the cylindrical section of the cyclone, and short-circuiting of newly arriving pulp is thus minimised.
