Desander, a kind of solid control equipment for sale in Pakistan

Desander, a kind of solid control equipment, is a combination of cyclone desander and shale shaker of drilling fluid. The hydrocyclone is made from high chromium cast iron for good rigidity.
The KOSUN desander is designed on the basis of particle setting principle. The separated medium-drilling liquid enters along the inner wall of clone spirally, depending on the pressure and speed produced by sand pump. Under the function of centrifugal force and gravity, the larger particles are sunk along the inner wall of clone spirally and drained from bottom outlet to be separated in shale shaker with smaller mesh. Other mediums are ascending along clone spirally to enter the third–class separation device from overflow outlet for further purification.
KOSUN desander is the second phase solids control equipment, it can be combine with desilter, to treat the drilling fluids, the most common cone is 8” or 10”, mainly separate size of 47-76μm solids particles out from drilling fluids. According to clients’ treating capacity can choose the number of cones.

Desander, as stated earlier, have no moving parts. The larger the internal diameter (ID) of the desander is, the greater the amount of fluid it is able to process and the larger the size of the solids removed. Desander (10 in.cone) are able to remove roughly 50 percent of those solids within the 40-50 micron range at a flow rate of 500 gallons per min (gal/min), while desilter (4 in. Cone) are able to remove approximately 50 percent of those solids within the 15-20 micron range at a flow rate of 60 gal/min. Micro fine separators are able to remove around 50 percent of those solids within the 10-15 micron range at a flow rate of 15 gal/min. Desander is typically positioned next-to-last in the arrangement of solids control equipment, with decanting centrifuge as the subsequent processing unit. Desander are preceded by gas busters, gumbo removal equipment (if utilized), shale shakers, mud cleaner (if utilized) and vacuum degasser.Desander is widely used in oilfield drilling.
