Model Selection Guide of Decanter Centrifuge

Many people can easily know how to choose a decanter centrifuge, but it is a little difficult for them to select a suitable model of centrifuge. Here is a simple method to judge a proper model for you.

decanter centrifuge
Decanting Centrifuge

First, the model of a decanter centrifuge represents the following meanings: For example, LW450*842, a model of decanter centrifuge, among which L means Luoxuan in Chinese Pinyin, W means Woshi in Chinese Pinyin, 450 means the bowl diameter of decanter centrifuge, and 842 means the bowl length of decanter centrifuge.

A suitable model of decanter centrifuge can not only solve production problems and improve work efficiency, but also save production cost and reduce business risks. Several main factors that determine the centrifuge model are as follows:

decanter centrifuge
decanter centrifuges

  1. Speed of decanter centrifuge: The speed of a common decanter centrifuge is more than 2000RPM. For some materials hard to separate, a higher speed is required. The higher the speed is, the higher the separation factor of centrifuge, the better the separation effect.
  2. Material of decanter centrifuge: PH value of materials to be treated determines the bowl material of decanter centrifuge. Different materials have diverse physical and chemical indexes in their abrasion and corrosion resistances. Overseas decanter centrifuges are generally made of 316L or duplex stainless steel, with wear parts made of ceramic materials.
  3. Differential control of decanter centrifuge: Different differentials have different control accuracies, service lives and maintenance costs. The higher its differential accuracy is, the better its adaptation to materials is. So it is advisable to select equipment with a high differential accuracy.
  4. Length-diameter ratio: The bigger the length-diameter ratio of decanter centrifuge is, the higher the handling capacity is, the lower the moisture content is.
  5. Control system: At present, almost all of equipment manufacturers at home and abroad have achieved a full automatic control over the equipment.
  6. Installed power: As for a control over energy consumption, generally speaking, domestic equipment has a higher energy consumption ratio, while foreign equipment has a lower one.
  7. Manufacturing technique: Since a decanter centrifuge is a kind of separation equipment with high precision machining requirements, the centrifuges manufactured by enterprises without a precision machining capability will suffer from a high maintenance ratio and a restricted handling capacity.

KOSUN DC Series Decanting Centrifuge Separation Principle

Decanting Centrifuge Separation Principle:Taking advantage of the principle that the light liquid, heavy liquid and solid phase, with different density and mutually insoluble in the mixed liquid, gain different sedimentation speed in the centrifugal force field or gravity force field, separating stratification or causing the solid particles in the liquid to deposit can be achieved.

Decanting Centrifuge
Decanting Centrifuge

KOSUN DC series decanting centrifuge is used in separating suspension of solids phase with particle diameter(d≥2μm) for drilling mud and fluids handling. Ruggedly built for oilfield and industrial services, it is especially effective in environmentally sensitive areas. It delivers high fluid-recovery rates and efficient solids control to significantly reduce the costs of makeup fluids and disposal. The centrifuge must test the dynamic balance for smooth operation over long periods.Speed ranging from 0 to 3900 RPM, generating centrifugal forces reach up to 3000G.

DC decanting centrifuge is 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 Solids Control of Decanter Centrifuge

In the whole solids control system, the drilling mud Decanter Centrifuge is the most important solids control equipment, it is the forth stage equipment and it decides the quality of drilling fluids in a way. The first equipment is oilfield shale shaker, it is one of the most important equipment, too. The second stage equipment is desander, third equipment is desilter. Sometimes they are combined to be as one equipment—drilling mud cleaner.

Oilfield Solids Control
Oilfield Solids Control

KOSUN Drilling Fluid Centrifuge is designed to speed up the settling process. The rotating speed is transformed into centrifugal force inside the rotating assembly to accelerate particle settling in accordance with Stoke’s Law. In essence, a centrifuge is a miniature settling pit that alloys very rapid settling of solids under controlled conditions. Though much more complicated than a hydrocyclone, centrifuges have the advantage of achieving extremely fine cut points. Centrifuges can improve the cut point by a factor of 6X when compared to a prototypical shaker/hydrocyclone system and can dramatically increase the drilling fluid life.

Decanter Centrifuge

KOSUN Decanter Centrifuge can effectively remove the harmful solid particles from the oil and gas drilling fluid, improve the mud performance, ensure the drilling safety, lessen the pollution of oil/gas reservoir and reduce the mechanical abrasion of drilling equipment. 1500-3000 rpm centrifuge can separate 2-7μm solid particles. It is an ideal choice for drilling mud purification.

Drilling fluids is important for the whole drilling system, but is too expensive, we usually spend abundant expense for that. But if we clean the drilling fluids and use it for recycling, we can save more drilling cost. At this time, the drilling fluids solids control of the drilling fluids seems to be so important.
