KOSUN desander is used as the 2nd stage of solids control for drilling mud, which makes separations between 45 and 75 microns. Desanders have no moving parts. The larger the internal diameter of the desander is, the greater the amount of drilling fluids it is able to process and the larger the size of the solids removed. A desander with a (10 inches (250 mm) cone) is able to remove 50% of solids within the 40-50 μm (micrometre) range at a flow rate of 500 US gallons per minute (32 L/s), whilea desilter (4 inches (100 mm) Cone) is able to remove 50% of solids within the 15-20 μm range at a flow rate of 60 US gallons per minute (3.8 L/s). Micro-fine separators are able to remove 50% of solids within the 10-15 μm range at a flow rate of 15 US gallons per minute (0.95 L/s). A desander is typically positioned next-to-last in the arrangement of solids control equipment, with a decanter centrifuge as the subsequent processing unit. Oilfield mud desander s are preceded by gas busters, gumbo removal equipment (if utilized), shale shaker, mud cleaner (if utilized) and a vacuum degasser. Desanders are widely used in oilfield drilling. Practice has proved that hydrocyclone desander is a kind equipment of economic and effective.
Desander Features:
1. Polyurethane(PU) Material or high-chromium cast iron for desander cones with longer using life.
2. Clamp type for easy maintenance.
3. Compact design with small footprint.
4. Flexible options for 1, 2 or 3 for different capacities.
5. Flexible fast connection is available for user assembly.
Nowadays, KOSUN possesses three factories all over the world: the first one specializing in producing solids control equipment and centrifuges in Xi’an China, the second one manufacturing all kinds of drilling fluid tanks, water tanks, oil tanks and pressure containers in Xianyang China, and the third one producing various drilling fluid tanks, oil tanks, water tanks and camps in Aktobe Kazakhstan.
