Haiwang de-sander and desilter are the second grading and third grading solid control equipment for the drilling fluid during the well drilling process, whose purpose is to remove the fine rock waste from well drilling liquid and decrease the solid content. It has high efficient sand removal and desilter efficiency, high separation accuracy, light weight, simple assembly, abrasion resistance, aging resistant and long service life etc. advantages.

During the later stage of oil well drilling, due to the deep well etc. reasons, it is required to prepare high-density mud. Because the drilling fluid density is relatively high and solid ratio is relative big, the conventional desilter cyclone cannot meet the site requirement, even with the possibility of underflow cutoff.  In line with such kind of situation, Haiwang FX-G mud purifier can effectively solve the above problems.
