Hydrocyclone Working Principle
- The third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE.
Dense Medium Cyclone Hydrocyclone Separator
The less dense material, due to the action of the drag force, settles more slowly. This material is captured in the upward flow of the reverse vortex and exits through the overflow. The medium density at which the separation between more dense and less dense material occurs is called the cut point density.
A hydrocyclone is a classifier that has two exits on the axis: one on the bottom (underflow or reject) and one at the top (overflow or accept). The underflow is generally the denser or coarser fraction, while the overflow is the lighter or finer fraction. It has no moving parts
Hydrocyclone OperationMineral Processing & Metallurgy
The cyclone underflow is directed to the ball mill- for further grinding. Once the ore has passed through this mill it will be added back into the material that is being pumped to the cyclone for reclassification. The hydrocyclone product is the overflow, which of course is finely ground rock. It is this overflow which must be controlled.
Wear-resistant linings are incorporated into the feed distributor, as well as the overflow and underflow launders. Metsos hydrocyclone manifolds incorporate all required work platforms with special attention to safe access for monitoring, sampling and maintaining the hydrocyclones.
The Top 5 Things You Need To Know About Hydrocyclones
Pressure at the inlet of the Hydrocyclone is an important indicator of where the separation point (also called cut point or d50) will be. The separation point is the size at which a particle has a 50-50 chance of reporting either to the underflow or overflow. When the pressure is below the target pressure, the d50 will be coarser than desired.
Hydrocyclones Hydrocyclone Separator
Performance is based on the configuration of the inlet area, vortex finder diameter, underflow and overflow diameters, cylindrical sections, and cone angle. Typical application of hydrocyclones. Minerals (e.g. Kaolin, Feldspar, Talcum, Chalk,Q uartz, Gypsum, Bentonite, Zircon)

water, is termed the overflow and should be discharged at or near atmospheric pressure. The higher mass particles remain in a downward spiral path along the walls of the conical section and gradually exit through the apex orifice. This product is termed the underflow and also should be discharged at or near atmospheric pressure.
Capacity Limitations of The Hydrocyclone Hydrocyclone
Capacity Limitations of The Hydrocyclone. The capacity of the hydrocyclone is essentially by the ability of the spigot opening to discharge solids. If the solids load is too high the solids content of the underflow increases and the viscosity of the discharged pulp

Optimization of hydrocyclone classification by on-line
overflow stream of a hydrocyclone using sensors mounted to the exterior pipe surface. It provides real-time monitoring, trending and alarming of the coarse material level. This enables operators to identify poorly performing hydrocyclones, and enables corrective action to reduce or eliminate the coarse material discharge.

The double-pass hydrocyclone process was able to enrich starch and protein in the underflow and overflow, respectively. The underflow resulting form the second-pass underflow contained high starch ranging from 89.80 to 99.71% with the starch separation efficiency was between 99.03 and 99.84%.
Abstract: This study proposed a new type of hydrocyclone. A rotating ring containing one pair of symmetric blades was attached to the overflow pipe. The momentum of the inlet fluid drove the ring/blades to rotate, and the rotating blades swept small-sized particles to the hydrocyclone wall to be discharged from underflow.

Hydrocyclone. Hydrocyclones concentrate solids in liquid suspension or classify solids at a desired particle size. They produce a continuous overflow stream containing the fine solids and a continuous underflow stream containing the coarse solids. Typical applications include: Separating coke particle from water or hot oil in refineries
