Abstract
A skid mounted first and second stage centrifuges, each being provided with an input pump. Drilling mud is delivered to the first pump, the first stage and then into a tank for storing temporarily the liquids separated from the mud. The heavier weight components are segregated, stored and later added back to the liquid discharge of the second stage to provide an output stream of drilling mud having a specified weight for use in drilling. The lighter weight components are removed at the second stage and are discarded to clean the mud. A control system provides for operation and control without overloading.
