For clarifying lube oils and printing inks (very fine solids in viscous liquids), which high-g device is most effective?

Introduction / Context:
Lube oils and printing inks often contain very fine particulates that are difficult to remove by filtration due to viscosity and particle deformability. High-g centrifuges exploit density differences to accelerate separation.

Concept / Approach:
Disc-stack centrifuges (often branded Sharples “supercentrifuges”) provide very high centrifugal fields and large clarifying area per footprint, enabling efficient removal of sub-microm to few-microm particles from viscous liquids. Sparkler and precoat filters work well for many duties but may clog rapidly on viscous streams and deformable fines. Standard disc-bowl centrifuges are effective, but supercentrifuges extend the g-range and throughput for challenging fluids like inks.

Final Answer:
Sharples (supercentrifuge, high-g disc-stack)
