Hydrocyclone size selection for mill concentrator applications: …
Have you ever asked for a hydrocyclone selection recommendation, only to receive just one option from the manufacturer? It's important to know that there are at least two options of hydrocyclone diameter sizes for most of the applications in mill concentrators, in addition to the many other features that could be considered for your particular application.

The Sizing & Selection of Hydrocyclones
3. Feed concentration – less than 1% solids by volume 4. Pressure drop – 69 kPa (10psi). 5. Cyclone geometry – "standard cyclone" as described above CLASSIFICATION Historically, classification has been defined as the particle size of which 1% to 3% reports to the cyclone overflow with coarser particles reporting to the cyclone underflow.

With these feed solids concentrations, even the coarsest particles in the CH partially report to the overflow, behaving like the in-between-size particles mentioned above. Fig. 8 b shows more details of particles at the spigot. It can be seen from the figure that in the separation process, the relatively coarse particles concentrate near the ...

This is referred to as 'bypass' or 'alpha' water. The greater the quantity of bypass water, the lower the efficiency of the hydrocyclone. If the underflow discharge pattern is erratic, it could indicate the presence of a foreign object inside the cyclone or erratic solids feed concentrations to the cyclone, or even pressure fluctuations.

Hydrocyclone Feed Pump and Pressure
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 …

The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds of times greater …
