GN desander and desilter consist of different size hydrocyclones to reach different treating capacity, we usually use 8”, 10”,12” cone as desander cone, and 4” cone as desilter cone. Although we have 3”,5”,6” cone, but usually we did not use it in our equipments , so as 20” cone.

High performance of hydrocyclone

Hydrocyclone is the most attractive device for removing solid particles from liquid . It utilizes the centrifugal force to effect the separation. The separation of solid from liquid depends on the particle size and particle density. Centrifugal force throws the particles out against the wall and they subsequently drop into the outlet hopper. Cyclone consists of vertical cylinder with conical bottom. The inlet point is near the top of the cylindrical portion. The particles separated are collected at the bottom. Our desander can separate 47~76μm particles, and desilter cone can separate 15~47μm particle.

Hydrocyclones are designed for separating solids from liquids and are successfully used in liquid/solids separation, classification, and concentration.they can be defined as fixed wall centrifugal separator devices that separate particles according to density and mass. Unlike other type of centrifugal separators, the liquid mixture rotates within the chamber.

Hydrocyclones used with a Vibrating Screen

A unitized combination of hydrocyclones and a vibrating screen to provide liquid/solids separation and achieve a dry cake. As a first stage, the slurry is processed through the hydrocyclones, the cleaned liquid is carried out the hydrocyclone overflow and the concentrated underflow(solids) are deposited on a vibratory screen deck. The screen deck imparts a rapid linear motion, producing an energy force that dewaters and conveys the solids to the discharge end of the screen. The screened liquid flows into a collection pan located below the screen deck. The cleaned liquid overflow from the hydrocyclones and the screened liquid may be blended together.

GN desander and desilter can be customized for with underflow shaker or not. We will recommend the proper type according to your application industry and treating target. For more information, pls contact GN solids control.

    Dear Sir,
    I would like to know if the desander and or the desilter can be used in redusing the water turbidity of 1000NTU to 5NTU for water to be used in human daily activities prodused by water purification units. Thank you with best regards.

    Gone through your site its maintained very nicely. I would like to know that the ground water used for daily use can be cleaned by your product. Present discharge of water is 2.5 L/S and contains some percentage of sand. Any other data required may kindly be intimated so that the same can be provided to you.
