GN supply 10 inch desander cone assembly and they can be assembled into desander unit by different numbers cones, usually it is 1pc, 2pc or 3pcs, according to client’s requirement. GN 10” desilters are designed to remove silt-sized (47-76 microns) solids from drilling fluids.

  • The GN ZQJ250S utilizes a combination of hydrocyclones and an small shale shaker(1.0m2 screen area, with one vibrating motor) to separate solids from liquid. The combination of hydrocyclones utilized is dependent upon the specific application of duty.
  • The cones are mounted above the screen deck of the shale shaker. The drilling fluid (mud) is fed first through the hydrocyclones, where the discharge cascades down over the shale shaker screens. This helps to reduce the amount of mud attached to the discharged cuttings.

What are the uses and limitations of Hydrocyclones?

A hydrocyclone is most often used to separate “heavy solids” from a liquid originating at a centrifugal pump or some other continuous source of pressurized liquid. A hydrocyclone is most likely to be the right choice for processes where “lights” are the greater part of the mixture and where the “heavies” settle fairly easily.

Generally, hydrocyclones are used in continuous flow systems so that the instantaneous liquid inflow to the hydrocyclone is equal to the total instantaneous outflow of “light solids” plus “heavies”. In cases where “heavy solids” are a very small part of the whole liquid, it is sometimes advantageous to accumulate them in the bottom of the hydrocyclone for batchwise removal.

ChemIndustrial’s modular construction methods make it easy for us to provide accumulation configurations.

In some applications, ChemIndustrial hydrocyclones are capable of sharp separations of “heavies” and “lights”. In other situations, they are used for incremental enrichment, reducing the load on other, more costly separation equipment and improving the overall economics of operation.

Hydrocyclones are generally not recommended for removing long fibers from liquids

Except 10” cone, GN also manufacture 3”,4”,5”,6” etc special size cone for various requirement, 8”, 10” 12” desander cone is available. For more information about hydrocyclones, pls contact GN solids control freely.

  2. Desander replacement for Derrick MI-Swaco Desander Says:

    […] Derrick 10 Inch Desanders […]

  3. NOV Mud Conditioner and GN Mud Cleaner Says:

    […] are a lot of names given to the combination of hydrocyclone and shale shaker. In NOV, it is called mud conditioner; while Derrick, flow line cleaner; Mi swaco, […]

  4. 10″ Derrick Desander cone Says:

    […] Desander cone can be made of polyurethane, as well as casting iron, and part of ceramics. All of the material are durable and anticorrosive to drilling fluid. For the clamp on the desander cone, they are stainless steel. And the clamps are rather easy-handling for tighting and untighting. […]
