Drilling decanter centrifuge http://www.kosungroup.com/products/solids-control-equipment/dc-series-de... separation principle is to use high-speed rotating roller driven into the mud in the high speed rotating drum, mud was dumped into the wall to form a liquid circle, solid phased particles of liquid ring get greater than its own gravity for undreds or even thousands of times the effect of centrifugal force, will overcome the resistance of the slurry viscosity to the roller on the inner wall of rapid subsidence formed solid layer, liquid forming liquid layer.
Decanter centrifugal pump is a subclass of turbomachinery technology. The main work of this type of pump is to bring up fluids through the transformation of the rotational energy into another energy called hydrodynamic energy. Typically, the rotational energy source is either the turbine, electric motor or engine.
