Inside a solids control system, desander may be the second stage equipment, which removes solids particle size 40-100 nm from drilling liquids. Then your next is desilter getting rid of particle size 16-50nm from drilling liquids. While, cone(also called hydrocyclone) may be the functioning part for desander and desilter. Based on the size cone diameter, cones are called desander cones having a the diameter over 6’’ so that as desilter cones having a diameter under 6’’. Generally, 8’’ and 10’’ cones are generally utilized as desanders 4’’ and 5’’ cones are often utilized as desilters.
You might be interested in the way a cones works. GN Solids America will tell you the answer within the following paragraph.
In normal operation, feed slurry needs tangentially in to the interior from the cone inside a high-speed, leading to whirlpool effects within the cone. The swirling motion from the slurry drives the bigger and denser contaminants outward from the cone wall for the lower discharge port, as the more compact, lighter contaminants move towards the middle of the cone and venture out with the upper discharge port. The separation of solids from drilling liquids is completed.
