Hydrocyclone Working Principle

The hydrocyclone operation consist of having the ore slurry pumped into its feed inlet, the ore is then separated by size with the fine material coming out of what is referred to as the “OVERFLOW” via a Vortex Finder. The mineral that still requires grinding is named the “UNDERFLOW” via the Apex Finder. These two terms, the “overflow” and “underflow” will become very familiar ...

Hydrocyclone - an overview | ScienceDirect Topics

Hydrocyclone. A hydrocyclone is a device that is used to separate oil droplets from wastewater based on the ratio of their centrifigal force to fluid resistance. A hydrocyclone has two exit points on the axis—a smaller one on the bottom (underflow or reject) and a larger one at the top (overflow or accept). The underflow consists of the ...

Hydrocyclones - an overview | ScienceDirect Topics

A hydrocyclone can handle very high slurry throughput rates, and often an entire battery of hydrocyclones can be found at a mineral processing facility. The advantage of fast processing by a hydrocyclone is somewhat offset by the associated high impingement wear rate of the hydrocyclone internal surface lining by the fast-moving abrasive slurries. For this reason, wear-resistant linings of …
