Drilling mud decanter centrifuge is the fourth stage equipments for a drilling mud system.Drilling mud cleaning first stage uses drilling fluids shale shaker ,then second stage uses desander,third desilter,(now drilling mud cleaner is widely used to replace desander,desilter).

The drilling mud decanter centrifuges can separate fine particles well,for separating 5~7μm particles in drilling mud,usually use medium speed decanter centrifuge,for less then 2μm,usually use high speed decanter centrifuges.

Principle of Operation
Bowl Speed – Depending on the model specification, drilling mud decanter cenrifuges are equipped with either fixed or variable speed arrangement on the main drive enabling the operator to adjust the bowl speed between 1200 and 3850 rpm within a few seconds.  This option, combined with variable conveyor speed, gives a unique dimension to the use of decanters for drilling fluids treatment. The optimum speed for solids removal for a specific cut point depends on the composition of the drilling fluid and the nature of the drill cuttings.

Decanter cenrifuge Scrolling Speed
Decanters are equipped with either fixed or variable back drive. The scrolling speed -(relative conveyor speed) can be changed in a matter of seconds by operations of a simple control switch. The optimum scowling speed is selected in each case according to solids load, required separation efficiency and required underflow density.

Feed Rate – In general a single drilling fluid decanter is capable of a process feed rate of up to 200 gpm. The treatment capacity is influenced by mud type and mud rheology. On drilling rigs it is common to utilize a minimum of two decanters installed in tandem for low weight muds and in series on high-density muds where barite recovery is necessary.
