650 Decanter Centriguge

Decanter centrifuge is the 4th solids control equipment in oil and gas drilling solids control system. By principle of centrifugal sedimentation separation, it is used to process drilling mud discharged from desilter and mud cleaner, separating solids particles from 2μm to 7μm. It is a solids control equipment to separate smallest solids particles, balancing mud viscosity and recovering mud weight.


BZ Decanter Centrifuge is mainly used in solid control of oil and gas drilling, drilling waste management, sludge treatment and other solid-liquid separation industries.

According to the different speeds, THE BZ CAN centrifuge can be divided into high-speed centrifuges, which are mainly used for solid control of oil and gas drilling and waste management. Medium speed centrifuge, mainly used for HDD, TBM and pile mud recovery. Similarly, the BZ centrifuge is optional in fixed-frequency and variable-frequency drives.

The BZ CAN analyzer centrifuge has a wide range of drum length and diameter ratios and is suitable for different applications. High capacity and good performance result in drilling fluid recirculation.
