The separation capacity of desilter is quite high and the size range of particle separated is extensive; the underflow port of hydro cyclones is like umbrella and sand can be deposited rapidly under pressure, reducing the probability of underflow port jams.

Advanced small shale shaker with two layers screen is of large capacity, low noise, long working life; and the symmetrical mechanism for liquid inletting makes the hydro cyclones distribute reasonably and work stably.

Desilter is designed according to the principle of particle sedimentation. The separation medium drilling fluid passes through sand pump and gets certain pressure and velocity, flows into spirally along the cyclone inner wall.

Coarser particles sink spirally along the cyclone inner wall under the action of centrifugal force and gravity, and are discharged from underflow port, falling down to the vibrating screen and being separated, the rest of the medium has risen in a spiral along the hydro cyclones.

Maintenance & repair methods of cyclone desilter:

1. The shaker screen box must be removed and the bolt must be locked after the first time use of new desilter or before the first use after moving.

2. When stopped using for a long time, please clean cyclone with clear water circularly, preventing dry sand piling up inside the cyclone.

3. Vibration motor note a grease each 1500 ~ 2500 hours, and oil quantity is 5 ~ 10 ml for each bearing.

4. Shaker screens should be cleaned after downtime, lest sediment dry solid, and desilter cannot be used next time. KOSUN desilters have very good performance and get good complimentary from our clients all over the world. The most common cone is 4” or 5”, mainly to separate the solids in 15-47μm out from the drilling fluids.
