Structural Features and Operating Principles of KOSUN DC450S Series Decanter Centrifuge

KOSUN DC450S Series Decanter Centrifuge is mainly used to recover barite, remove fine solids, reduce solids content of drilling fluid, control density and viscosity of drilling fluid, and plays an important role in guaranteeing drilling fluid property and fast drilling.


The bowl of KS DC450 Series Centrifuge consists of cylindrical bowl and tapered bowl. There are 8 or 6 liquid discharge outlets distributed in the circumferential direction of big-end plate of bowl, and the liquid level is controlled by movable weirs. For various needs of different materials and separation dryness, the liquid level is adjusted by relative positions of movable weirs: the larger for R value, the shorter for sedimentation area, the longer for drying area and the drier for solids separated. Conversely, the longer for sedimentation area, the less for solids content of liquid separated and the wetter for solids. There are 22 solids control discharge outlets lined with hard alloy bushing blocks evenly distributed at radial double rows of small end of tapered bowl.

The screw conveyor consists of cylinder, cone and flights. The mandrel composed of cylinder and cone has 24 feed nozzles, which make materials smoothly enter the cavity between screw conveyor and bowl from its interior under the effect of centrifugal force. Flights are welded to the mandrel to form a spiral line and edges of flights are sprayed with a layer of wear-resisting hard alloy. The clearance between flights and bowl is about 1mm for smooth discharge of deposited materials.

KOSUN is capable of providing customers with such three series as oil & gas drilling solids control equipment, decanter centrifuges, shale shaker, mud gun, mud agitator, vacuum degasser, jet mud mixer, mud cleaner, desander, desilter and drilling waste treatment equipment, including 25 categories of products, which are extensively used in oil & gas drilling and workover, coalbed methane drilling, shale gas drilling, water well, geothermal well drilling, trenchless horizontal directional crossing projects, mine gravel staged treatment, tailings treatment, rive dredging works, industrial wastewater treatment, environmentally friendly sewage treatment, waste oil recovery, purification treatment, etc.
