High quality drilling mud decanter centrifuge equipment, sludge dewatering centrifuge, centrifuge decanter

Working principle                                                                                                                    

LW drilling mud decanter centrifuges are designed specifically to remove unwanted solids and fine particles from virtually all kinds of used frilling mud, including those based on water/synthetics and conventional oil-based drilling fluids.

Drilling muds are based on water, oil pr polymer with a composition of various additives such as flocculents, surfactants, detergents and more. By means of modern drilling mud system includes decanter centrifuge, cutting dryers, shakers, etc, everything brought into the mud by the frilling process will be separated. The clarified mud will be returned to the drilling rig

Separation takes place in the horizontal bowl equipped with a scroll conveyor. The drilling mud is feed into the bowl through a stationary inlet tube and is smoothly accelerated in the accelerate chamber. Centrifugal forces cause instant sedimentation of the solids on the wall of bowl. The conveyor rotates in the same direction as the bowl, but a different speed, thus moving the solids towards the conical end of the bowl.    

Design Feature                                                                                                                         Vertical base design and symmetrical arrangement of motor and bowl assembly, that ensures stable operation and less vibration.

Main parts such as the bowl and conveyor are made of corrosion-resistant stainless steel or duplex steel, offering high maximum bowl speed and high centrifugal force.

The basic principle is the drum and the spiral feeder rotate in the same direction but with a certain speed difference: The material is led into the feeding spiral inner cylinder via the feeding pipe and after speeding up, enters the drum: Under the action of the centrifuge force field, the relatively heavier solid-phase material deposits on the drum wall forming the residue layer: The solid-phase residue is continuously pushed by the spiral feeder to the conic end of the drum and after dehydration in the drying area, is discharged under full-speed running.
