 LW series Decanting Centrifuge

LW series is a normal decanting centrifuge mode of our company, they are ideal choices for separating particles in drilling mud. Decanting Centrifuge separate the suspending fluids using  the principle of centrifugal action, the suspending fluids is pushed into the rotor drum through the inlet pipe and the fluid hole of the spiral feeder. Under the influence of centrifugal force, solid phase particles are pushed to the internal wall of the drum, then to the mud export of the small end of the drum and excreted. But the fluids is excreted from the overflow hole of the large end. Such cycle is in order to achieve the purpose of continuous separation.

High speed decanting centrifuge are effective for separation.

Oilfield Decanter Centrifuge For drilling fluids

Decanter centrifuge are used to process un-weighed and weighed, water-based and oil-based drilling fluids (muds). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system. oilfield Decanting Centrifuge are able to apply over 3,000 G-forces on the liquid/solids mixture, which separates the heavier solids from the lighter solids. Additionally, high G-forces separate fine solids from liquid.
Mechanical separation of solids from the mud system through the use of a decanter centrifuge is a highly-effective means of maintaining proper mud weight and viscosity. When used in conjunction with other
Solids control equipment, decanting centrifuge enable users to maintain the mud properties within the prescribed range as per the drilling program. Typically,oilfield decanting centrifuge is the final processing units in the arrangement of solids control equipment. Decanting centrifuge preceded by gas busters, gumbo removal equipment (if utilized), shale shakers, mud Cleaners (if utilized), Vacuum degassers and hyrdocyclones.
