Decanter centrifuge is a horizontal solid bowl centrifuge with scroll conveyor inside. Our purpose designed drilling mud decanter centrifuge comes with high wear- resisting and excellent corrosion-resistant performance.

Last week, DC Solid control shipped a set of DCLW355-1257 high speed centrifuge to Australia. Decanter Centrifuges for oilfield applications are often introduced to deal with drilling mud within active solids control system or waste effluent of drill cuttings. To meet the user’s requirements, electric parts of the centrifuge are all from Siemens or ABB.

Features of DCLW355 VFD Decanter Centrifuge:
1. Designed with high speed. The max speed can reach to 3400RPM
2. Made of selected material. The main body and main parts of the decanter centrifuge are made of selected stainless steel material. So, our centrifuge can resist rust or erosion.
3. Stainless steel with the tungsten carbide alloy protection can ensure a longer service life of the centrifuge
4. High quality and competitive price
5. Fast delivery and good package

DCLW Decanter Centrifuges for oilfield applications are often introduced to deal with drilling mud within active solids control system or waste effluent of drill cuttings. With middle speed decanter in operation, barite can be recovered and high speed decanter for the removal of undesired ultra fine solids.
Our purpose-built oilfield decanters are abrasion resistance, combine long life with capacity and performance, require less maintenance time and reduce down time.Top rated explosion proof motors with approvals of IEC Ex, ATEX, UL for option for hazardous area, wired with 460V / 60Hz, 380V / 50Hz.

DC Mud equipment company got an new order of decanter centrifuge from Thailand. Now the drilling fluid centrifuge wil delivering to the port.

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 high-speed, solids control decanter centrifuge removes ultra-fi ne drill solids of greater than 2 to 5 microns at an average process rate of approximately 20 percent of the mud pump flow rate, Anderson continued.

A centrifuge also can be used as a barite recovery system or dewatering system, a practice widely used in the oil and gas industry. The dewatering process, said Anderson, allows up to 100 percent removal of all suspended solids from the drilling fluid. The reclaimed water can be used to make up new mud for another job or as rig wash-down water.

Drilling fluid centrifuge is the fourth stage equipments for a drilling mud system.D rilling 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). Centrifuge mainly separate particle sized 2-7microns.

Drilling rig centrifuges have got large development on both structure and functions. Especially there are many manufacturers design centrifuges according to drilling mud features or property. Then the centrifuge become many models and types used in various drilling projects.

Actually, in drilling rig solids control system centrifuge is the most complicated one. It is rather difficult for operator get leagal operation, etc. However, in long term its important position is following shale shaker subsequently

Decanter centrifuge are used to process unweighted and weighted, 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

We all know, decanter centrifuge works principle is centrifugal force precipitate. And the main part to realize the separation is the drum. But do how much do you know the drum. Following is the description of the decanter centrifuges drum.

Drum diameter-D

In the condition of other ceteris paribus, the production capacity of centrifuge is directly proportional to D3. According the size of diameter, foreign centrifuge have already serialization. The diameter is stated by our country is 200, 450, 600, 800, 1000mm. The diameter of foreign centrifuge is 6, 8, 10, 16, 20, 25, 30, 40 in.

We know that when centrifugal force is equal, the drum diameter is bigger, the rotary speed is lower. The retention time of solid phase particles in drum is longer, it can make fine solid phase particles have full times to settle to the wall of drum in the function of centrifugal force and discharged through screw pusher.

Drum length -L

Usually the drum length according to the diameter ratio to confirm, to the difficult separation material, the major axis ratio is 3-4. The length of drum is big, the volume of centrifuge setting pond is big, the retention time of solid phase is longer, so the separation effect is good. But the major axis ratio is limited by manufacturing technique and dynamic balance, so it can evaluate at well. To the difficult separation suspension liquid, the most reasonable method is improving the long diameter ratio in the condition of small diameter.

Drum shape

The drum shape has cone and tapered column the two basic structures. When drum length and diameter is fixed, the tapered column can provide bigger internal precipitation space to make the retention time of solid phase particles is longer in drum, the separation ability is stronger. Compared with cone drum, one is in the condition of treating is unchanged can keep the lower separation sizes; two is the throughput is bigger but the solid phase separation size is not changed. Because these reasons, drilling fluid treatment used centrifuge all use tapered column drum.
