Hydro cyclone has no moving parts. It consists of a conically shaped vessel, open at the bottom, variously called the underflow, apex or spigot, and connected to a cylindrical section which has a tangential feed inlet. The top of the cylindrical section is closed with a plate through which passes an axially mounted overflow pipe. The pipe is extended on to the body is the cyclone by a short, removable section known as vertex finder, which prevents short- circulation of feed directly into the overflow.
