What is a hydrocyclone used for and how does it work? | Weir
A hydrocyclone consists of a cylindrical top with an offset feed inlet pipe, an overflow outlet on top and tapered cone(s) leading down to a small outlet on the bottom. Other parts include external casings that contain the internal pressure and are clamped or bolted together, and internal replaceable liners for wear resistance.
