Operating principles
Oil-base mud cuttings enter the top hopper of vertical centrifuge and fall onto its internal
separation area. The internal cone rotates at a high speed of 900RPM and generates a centrifugal
force of 430G. For density difference between liquid and solids, mud is hurled out of surface of drilling
cuttings and passes through screens, and solids are retained inside the screens. And then, liquid is
discharged from the liquid outlet and dry solids are discharged from the bottom of equipment.

- Features & Benefits:
- Efficient solid-liquid separation. Liquid content of treated solids is up to national and industrial standards.
- Effective recovery of treated liquid for recycling in drilling solids control system.
- Greatly reduce solid discharge volume, drilling fluid cost and waste management cost.
- Meet field operation requirements on zero discharge of drilling waste.
- Rotate at a high speed of 900RPM to generate a centrifugal force of 430G and effectively separate liquid from cuttings.
- Flights coated with wear-resistant material and metal screens for longer service life.
- Intelligent pulse jet control system effectively prevents screen blockage.
- Separate oil circuit lubricating and cooling system for simple and reliable operation.
- Integrated programmable control system for safe and convenient operation.
- Feed/discharge ports can be equipped with screw conveyors to facilitate drilling cuttings conveying and continuous equipment operation.
Treatment Effects of Vertical Centrifuge
For oil-base and synthetic-base mud: water content of solids treated by the vertical centrifuge is below 6%.
