CentrifugesCentrifuges

Important points to operate centrifuges

The process of the Centrifuge• Remove solids of high and low gravity• Centrifuge Bowl Adjustment: Deep for an optimum cut,

and less depth for more volume. • High RPMS: for more G force; • Low RPMS: For solids with more specific gravity.• The operator has to look for the optimum adjustment

depending on the process.

The Function of the Centrifuge•To remove the solids which are the most dangerous to the mud which are 5-10 microns in size •produce a dry cutting.•Barite recovery •De - watering: Solids and fluids separation with polymer enhancement.
