Desander and desilter are solid control equipment with a set of hydrocyclones that separate sand and silt from the drilling fluids in drilling rigs.
Desanders are installed on top of the mud tank following the shale shaker and the degasser, but before the desilter. Desander removes the abrasive solids from the drilling fluids which cannot be removed by shakers.
Normally the solids diameter for desander to be separated would be 45~74μm, and 15~44μm for desilter.
