The Sizing Selection of Hydrocyclones

The particles migrate downward in a spiral pattern through the cylindrical section and into the conical section At this point the smaller mass particles migrate toward the center and spiral upward and out through the vortex finder discharging through the overflow pipe This product which contains the finer particles and the majority of the water is termed the overflow and should be

Inertial microfluidics for continuous particle separation

Using this concept we demonstrate for the first time a spiral lab on a chip LOC for size dependent focusing of particles at distinct equilibrium positions across the microchannel cross section from a multi particle mixture The individual particle streams can be collected with an appropriately designed outlet system To demonstrate this principle a 5 loop Archimedean spiral microchannel

Spiral Classifier

The spiral classifier is a kind of equipment for mechanical classification based on the principle that the specific gravity of solid particles is different so the speed of precipitation in the liquid is different The coarse material is screwed into the feed port of the mill using a spiral blade and the filtered fine material is discharged from the overflow pipe There are four types of
