Cyclone separators or simply cyclones are separation devices (dry scrubbers) that use the principle of inertia to remove particulate matter from flue gases. Cyclone separators is one of many air pollution control devices known as precleaners since they generally remove larger pieces of particulate matter. This prevents finer filtration methods from having to deal with …

Hydrocyclone separators are used worldwide in the mining and mineral processing industries for classification, de-sliming and de-watering applications. Their main purpose is to separate a stream of particles into different size fractions. However, they are also effective in applications where a fine slime fraction requires removal or where solids need to be dewatered as much as possible.

At low flow rates, the fluid spins at a lower velocity and the overall efficiency declines. At high flow rates, turbulence inside the hydrocyclone reduces efficiency. As a result, hydrocyclones work most efficiently at an intermediate flow rate, he said. Hydrocyclones can be installed downhole and have worked well in some reservoir performance ...

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 …

How does a hydrocyclone work? The hydrocyclone uses the pressure of the incoming fluid to generate a centrifugal force and flow pattern that can separate particles from a liquid medium. These particles must have a sufficiently different density to the liquid medium for separation to occur. The flow pattern in a hydrocyclone is cyclonic.
