In oil drilling, their maybe 2 stage centrifuge for solids control slystem. The first centrifuge recovers barite and the second centrifuge dries it’s centrate and recovers valuable fluids.

For 2 stage centrifuge to be efficient, the first centrifuge must make a god separation since most of the solids in it’s centrate will be discarded.The poorer separation, the more barite will be carried over in the second centrifuge. Similarly, the second centrifuge mud operate at the highest possible G force to remove the most solids.
