How does a DeSander hydrocyclone work? Slurry containing suspended sand or grit is introduced into the unit via a tangential inlet designed to generate a vortex action. As the liquid swirls inward, sand is pushed outward towards the cylinder wall due to extremely high centrifugal forces.

hydrocyclone mud desander with diameters of 100mm and 125mm are called desilters. When the working pressure is 0.2MPa, the processing capacity of a single cyclone is 10 ~ 15m3 / h. Under normal operation, the desilter can remove 95% of the drills larger than 40μm. Cuttings and 50% of drill cuttings larger than 15μm, and can simultaneously ...
The hydrocyclone has a free-surface air-core enclosed by the rotational vortex. The desander has a flooded-core instead. For the hydrocyclone pressure at overflow (Po) and underflow (Pu) are atmospheric (zero). For the desander Pi>Pu>Po – the underflow pressure (in accumulator chamber) is between the inlet and overflow pressures.
The compact inline HiPer desander, used a standalone or in combination with a HiPer desander hydrocyclone, provides continuous removal of sand and solids which protects downstream equipment from unwanted accumulation and …
Small diameter (12 to 100 mm), high efficiency desander cyclone liner are typically made of ceramic materials to provide excellent erosion resistance. If the particles to be removed are in excess of 50 microns then the use of single large diameter hydrocyclones (>150mm) becomes an option. ... Hydrocyclone Retrofits, Upgrades, Spare Parts and ...

And Cyclone Desanders and Desanders without bottom shaker ...
A hydrocyclone is a conical equipment, which employs centrifugal force produced by pressured flow to separate solids and oil particles from oily wastewater, depending on their density difference (Fig. 15).They typically feature a conical base and a cylindrical top section where the liquid is fed tangentially. Pressurizing the intake flow induces cyclonic development in the …
desander hydrocyclone after preliminary precipitation. The overflow from the desander, which contains the smaller solid particles, is piped to the desilter (Fig. 1) for secondary swirling, and a horizontal screw centrifuge concentrates the underflow of the desander and desilter into a solid phase. The water produced during the concentration ...
desanders make separations between 40 and 100 microns and offer the flexibility of mounting either one, two, or three 10" desander cones over a cone underflow pan. The underflow can be discarded or directed onto a vibrating screen for further processing.
