Comparison of drilling hydrocyclone desilter and desander

Drilling fluids desilter is used as the 3rd stage of drilling mud solids control equipment, which makes separations between 15 and 45 μm.

Desilter is a combination of desilter hydrocyclone and shale shaker screen. The polyurethane is used for hydrocyclone. The lower little shale shaker is elliptical. The vibration generator is driven by vibration motor, which makes the screen box keep a integral forward elliptical motion.

Drilling fluids desander is used as the 2nd stage drilling fluid solids control equipment of drilling fluids system.The oil drilling desander makes separations between 45 and 75 microns. According to your treating capacity, you can choose the quantity of cones for desander.

According to the size of the cone diameter, desilter is distinguished with desander . Generally, that of the cone of the diameter less than 6″ is called desilter, and used as the third control equipment in drilling operation. We commonly used 5 "and 4" cone to separate solid-phase particle size 15-47μm in the drilling fluid. Desilter cone is different only in size from desander, working principle are exactly the same.

As a key part of drilling fluids solids control equipment desander and desilter for separating solids, hydrocyclones in different specifications work against different diameters and for different cleannesses. Besides, separation capacity is closely related with cyclone diameter since larger diameter is aimed at larger particles while smaller one contends with smaller particles.
