Decanter centrifuge is the five-phase solids control equipment for processing drilling fluid in drilling operations, it is the last stage equipment in drilling mud system for solids control and mud cleaning. According to different rotary speeds, it is divided into medium speed centrifuge, high-speed centrifuge and Variable Frequency Drive VFD decanting centrifuge. BOBAN series decanter centrifuge removes the solid particles with size 2-7 microns using the principle of centrifugal action, it is an ideal choice for separating particles in drilling mud. Always there is a screw pump or submersible pump to feed the mud to Decanter Centrifuge. After the drilling fluids being fed into the centrifuge drum, under the function of centrifugal force, solid phase particles are pushed to the internal wall of the drum, then to the solid discharge export of the small end of the drum and excreted. While the fluids is excreted from the overflow hole of the large end. Such cycle is to achieve the purpose of continuous separation. High speed decanting centrifuge are more effective for separation of fine solids.

LW means horizontal spiral type which is a normal model of decanting centrifuge. BBLW series decanter centrifuge has two control modes: variable frequency and industrial frequency, also available for various decanter centrifuges for offshore drilling platforms. Industrial frequency drive decanter centrifuge can change the speed by changing the pulley and belt. Variable frequency horizontal centrifuge can achieve a wide range of step-less speed changes, and its control cabinet can directly display the working speed, working current and torque parameters. Our decanter centrifuge engine can be applied to 50Hz and 60Hz power grids, and also equipped with mechanical and electrical double overload protection devices, safe operation.
