Basics of a Hydrocyclone. Hydrocyclones (also referred to as cyclones) are an efficient way to separate slurries. With no moving parts, they depend on the feed pressure, or velocity, into the cyclone to generate a centripetal force. This centripetal force allows the cyclone to separate coarse or dense particles from fine particles.

Hydrocyclones were invented in the late 1800s and became widely used in mineral processing because they are relatively inexpensive, process high volumes, take up minimal floor space and have no moving parts. Hydrocyclones are commonly used for desliming, dewatering and sizing -4mesh (5mm) particles. They can be used in industries such as …

Abstract Hydrocyclones are widely applied in both chemical and mineral processing industries. Despite its simple design, the flow behaviour that governs separation within the device is quite complex and therefore difficult to control. Overall process efficiency, together with economics, promotes the development of an effective monitoring technique. In the …

hydrocyclone performance. The d50 (cut size) parameter is a key factor in hydrocyclone performance. The cut size is defined as the size at which a particle has a 50% probability of leaving the hydrocyclone through either the underflow or overflow.

A pneumatic diaphragm pump driven by an air compressor was used as the oil injection pump (P-01). It introduced a buffer tank downstream to inhibit the oil emulsion during pumping. An oval gear flow meter was used to measure the flow rate of the oil. A jet pump (P-02) generated the main water flow in the hydrocyclone.

The gas moves toward the center of the hydrocyclone with the oil and exits the unit through the reject port. A small amount of gas can improve performance, but too much gas disrupts the smooth flow of the oil core and bottlenecks the flow of oil out of the reject, Walsh said. Important trade-offs must be considered when designing a …
