In drilling fluid solids control system, drilling mud decanter centrifuge always used as the last stage solids control equipment,which adopts centrifugal force to separate solid particles out of drilling fluids. Drilling mud decanter centrifuge is widely used in oil and gas drilling, chemical, foodstuff, pharmacy, mineral beneficiation, water treatment, etc.

Drilling mud decanter centrifuge is used to separate solids particles with diameter ≥2μm out of drilling fluids. Different solid or particle have different density and flow speed, drilling mud decanter centrifuge also can separate particles as different size and density. After treatment, the drilling fluids can achieve ideal viscosity and proportion, results in better recycling, high efficiency, saving and environment protection. Founded in 1992, KOSUN is a a professional decanter centrifuge supplier in China. KOSUN Drilling decanter centrifuge is usually 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, municipal environment-friendly sewage treatment, industrial wastewater treatment, fruit juice purification, waste oil recovery and purification treatment, etc.

KOSUN DC series drilling mud decanter centrifuge developed and is equipped with the explosion-proof variable frequency solids control system which could adjust separation factor and drum rotational speed.A VFD (Variable Frequency Drive ) module monitors and controls both the main and back electric drives. The operator can manage bowl and scroll speeds via a touchscreen that also displays stats from the various sensors, including temperature, current, rotational speed and vibration.Due to this new technology, make the decanter centrifuge to adapt property changing of mud during the operation process, that make the treatment more effective and perfect.KOSUN drilling mud decanter centrifuge is high in recovery rate, effective in solids control and remarkable in the reduction of cost spent on solids control system.

Drilling fluid decanter centrifuge working principle:drilling decanter centrifuge is driven by two motors. The main motor drives the drum and differential shell rotation by the belt . The vice motor drives the spiral through the differential variable speed . The drum and spiral rotate together in the same direction, but at different speeds . Separate the solid phases in the drilling mud by the centrifugal sedimentation principle. Suspending fluids is pushed into the rotor drum through the inlet pipe and under the force of screw propeller, under the effect of centrifugal force, the solid phases will be pushed onto the inside wall of the drum, pass the impeller on the screw propeller and be discharged from the exhaust hole at the small side of the drum. The fluids is excreted from the overflow hole of the large end. So continuous circle like above to achieve the target of continuous solid-liquid separation.
