Optimising small hydrocyclone design using 3D printing and ...
2018-10-15 The use of 3D printing allowed to investigate the the effect of the vortex finder and spigot on the performance of small hydrocyclones in detail. A comprehensive study of vortex finder and spigot diameters in small hydrocyclones was performed in a full 3 2 factorial design. The trade-off in performance between the recovery of solids and concentration ratio was observed.

Vortex mechanism in hydrocyclones - TNMSC
The main concept of the mechanism is that the vortex flow in a hydrocyclone is resulted from the overlapping of container rotation and hole leakage. The model is then used to explain the compound distribution of free vortex and forced vortex, predict the similarity of tangential velocity at different input pressures, and make count of the principle of small hydrocyclone with lower cut-size ...

The Sizing Selection of Hydrocyclones
2016-2-16 vortex finder. The primary function of the vortex finder is to control both the separation and the flow leaving the cyclone. Also, the vortex finder is sufficiently extended below the feed entrance to prevent short circuiting of material directly into the overflow. The size of the vortex finder equals 0.35 times the cyclone diameter.

Designing vortex finder structure for improving the ...
2017-1-1 Large particles migrate toward the wall and are collected in the underflow, and small particles have a higher opportunity of migrating into the secondary vortex to flow out through the overflow. Because a hydrocyclone has the advantages of low investment, maintenance, and operating costs, it attracts not only process engineers but also academic researchers.

Hydrocyclones McLanahan
Hydrocyclones are ideal for recovering down to 400 mesh (38µm) particles of 2.7 SG. This is typically done in the form of an Ultra Fines Recovery system comprised of a Sump, Pump, Cyclones and Dewatering Screen, which will have a discharge to waste nominally 90% passing 400 mesh (38µm) and a product discharging the screen in a drip-free, readily conveyable and stackable form.
