Centrifuges are quite popular in separation industries, in oil and gas solids control, in drilling cuttings waste management, and in oily sludge separation projects. It is perfect solution for separating out particles from 2 microns to 5 microns. The centrifuges are playing more and more important role. But still, it is more difficult to operate the centrifuge well and let the centrifuge to work more efficiently.

There are some suggestions to help improving the centrifuges’ performance:
1. Before using the decanter centrifuge, make sure the material which enters the centrifuge are not so big for the centrifuges, in order to avoid blocking of centrifuges. For instance, a high speed centrifuge is capable to separate out particles from 2 microns to 5 microns. In practice, particles no larger than 2mm could enter the centrifuges. So it is suggested to use a shaker unit before the centrifuge.
2. How about when the particles are too small? When there are so many extra fine particles, it would be difficult for the centrifuge to separate the particles out. In this case, a chemical dosing unit is invited before the centrifuge. By adding flocculant into the material, the extra particles flocculate into bigger ones in order to be separated by centrifuge.
3. If the material is of too high viscosity, some polymers fed by the chemical dosing unit into the material, to lower down the viscosity. Then the separation result would be much enhanced.
4. Confirm the material content before choosing a suitable bowl rotating speed and a suitable differential speed. The material content information includes: solids content percentage, the distribution of each particle size, and etc. Such information helps the operator to adjust the centrifuge parameters.
GN Solids Control is quite professional in centrifuge design and manufacturing, GN centrifuge sizes range from 9 inch bowl to 30 inch bowl. Pls contact GN for consultancy.
