Desander is a secondary solid control equipment for drilling fluid treatment. This solid control equipment has a set of hydrocyclones that separate sand and silt from the drilling fluids in drilling rigs and 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.
Most common sizes are 8″, 10″, 12″ and 14″ for Desander for oil drilling mud system and 14″~20″ Hydrocyclone for Desanders for micro-tunneling separation plant.
