In its turn, the throughput index for a centrifuge is calculated as follows: Σ = F av ·K av. where: F av = 2·π·L·(R+r) – is the average separation surface, m²; L – drum length, m; R – inner radius of a, centrifuge, rotor, m; r – inner radius of slurry ring in a centrifuge, m;

The liquid ,mud, passes through the screens and is recirculated back to the ,mud, tanks from which ,mud, is withdrawn for pumping downhole. The drill cuttings remain on top of the shale shaker screens; the vibratory action of the shakers moves the cuttings down the screen and off the end of the shakers to a point where they can be collected and stored in a tank or pit for further treatment or ...

The rotor can be several meters in length (diameter is likely to be less than 10 cm) and a temperature gradient of 300 °C between the top and bottom of the rotor produces a very strong convection current. In addition, the very strong Coriolis forces produced add to the separation efficiency. To reduce friction, the rotor spins in a vacuum.

RCF is dependent on the speed of rotation in rpm and the distance of the particles from the center of rotation. When the speed of rotation is given in rpm (Q) and the distance (r) is expressed in centimeters, RCF can be calculated by using the formula in Figure 2. See the g force calculator to easily convert RCF to RPM and vice versa. Figure 2.

How a Centrifuge Works – Federation Of American Scientists

The heart of a gas ,centrifuge, is a tube, called the ,rotor,, that spins at high speed around its long axis. The performance of the ,centrifuge, depends critically on the speed of the ,rotor,. Technical advances in materials, high-speed bearings, and precision machining are what have made increased ,rotor, speeds possible and made centrifuges practical.

In particular, the target enrichment capacity of the IR-2m centrifuge (with outer wall speed 700 m/s and an effective rotor length of approximately one meter) was about 11 kg U SWU/year. 14 The IR-2m has two carbon fiber rotor tubes and one bellows, and thus an average effective rotor segment length of approximately 0.5 meters and an average output of about 5.5 kg U SWU/year per rotor tube.
