Jul 03, 2012 ΗYDROCYCLONE By : Budhi Raharjo Sigit Mintarjo INTRODUCTION Hydrocyclones are density separators that convert pressure energy into rotational momentum. The rotational momentum provides the centrifugal force to separate solids from a primary liquid. Separation efficiency is determined by the hydrocyclone geometrical parameters. The interaction between parameters dictate the hydrocyclone ...

A hydrocyclone is most often used to separate "heavies" from a liquid mixture originating at a centrifugal pump or some other continuous source of pressurized liquid, or two-phase (gas-liquid) systems. A hydrocyclone is most likely to be the right choice for processes where "lights" are the greater part of the mixture and where the "heavies" settle fairly easily. Generally, hydrocyclones are used in continuous flow systems so that the instantaneous liquid inflow t

May 14, 2020 Hydrocyclone is an effective fine particle classifing equipment in the present mineral processing equipment. Its structure is relatively simple, with a cylinder on the top and a conical container on the bottom. The slurry is fed into the hydrocyclone at a certain speed along the tangential direction, which generates a large centrifugal force due to the rotary motion.

Aug 07, 2015 For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump box that causes this pressure fluctuation.. First the pump pumps all of the slurry out of ...
