The drilling mud decanter centrifuges can separate fine particles well,for separating 5~7μm particles in drilling mud,usually use medium speed decanter centrifuge,for less then 2μm,usually use high speed decanter centrifuges.

The drilling fluid centrifuge is mainly used for the separation of the suspension containing fine/ medium particles, and the solid particles of granular, crystal or fiber, especially for the separation of material whose viscosity is high, with fine fineness, it’s poisonous or inflammable. It is widely used in the industries of chemical, pharmaceutical, food, light industry and environment protection, etc.

Centrifuge used in drilling solids control is the decanter type. Almost the decanter centrifuge used at drilling site are horizontal type. There are bowl, drum, conveyor, motor, control panel consisted in centrifuge assembly. Of course, also the support base or base frame.

oilfield centrifuge

Decanting centrifuge in drilling fluids system is used after desilter cone or mud cleaner. It can handle the solids ranged 2-7 microns. There are middle speed and the high speed one, the fixed frequency or VFD one. Treating capacity / handling rate varies along with centrifuge size. Usually, it is from 30~60m³/h. We can select screw pump or slurry pump as feeding pump.

Our Decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (mud). 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.

A decanter centrifuge from DC Machinery are painting now

The decanter centrifuge ordered by my Russian client are painting now this morning. It is used for oil drilling site to process the drilling fluid and located after the desilter.

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.

IMG_1270

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..

So DCLW centrifuges have adopted new technology on conveyor. Such as mount carbon tungsten alloy plates by welding and bolts. This increase centrifuge conveyer usable life and whole equipment duration.

3-Phase centrifuge produced by DC Machinery

DC Machinery is a profession manufacturer of design and produce two and three phase centrifuges. The DCLW series is a screw decanter centrifuge with a special specification. It enables three-phase separation of Oil, Water and Solid matter based on previous two-phase separation using the difference in specific gravity between solid and liquid.

centrifuge

Three-phase centrifuge separation by unique structure:

Separation of light and heavy liquid has been made possible by adopting the special structure of a liquid outlet dam. We also have various options available, and have good advancements for palm oil manufacturers with our high-G and anti-wear specification machines.

Working Principle:

Using two different size dams for liquid outlets, light liquid and heavy liquid separated using the centrifugal effect can be discharged separately.

centrifuge

Specifications:

1. Disposal volume is in the case of press water for fish meal, and can be altered according to the liquid disposed.
2. Motor Output can be altered according to the adopted centrifugal effect. *= On the condition of no common bed

You are welcome to contact DC Machinery to get more detailed info, we will supply our best service for you.

What Is The Working Principle Of Decanter Centriguges

The centrifuge is fed through a stationary pipe, which is inside a hollow shaft connected to the rotating screw conveyor (scroll.) There it enters a feed compartment and is accelerated through feed slots into the rotating bowl. Once inside the bowl, centrifugal forces accelerate the heavy solids, where they settle on the bowl wall. The lighter liquid will fill the bowl to the level of the effluent dam (weirs).

decanter centrifuge

The conveyor is connected to a gearbox and turns slightly slower than the bowl. Since it is turning slower and the helix is angled toward the small diameter (conical end) thus the solids are then conveyed along the bowl wall to the solids discharge end and discharged there.

The liquid flows around the conveyor and exits over effluent dam located on the large diameter end of the bowl. Lighter Solids, which did not settle to the inside diameter of the bowl (floaters), are carried out with the liquid over the effluent dams.

centrifuges

The Effluent dams are adjustable and control the amount of liquid inside the bowl. The Effluent Dam diameter is normally larger than the solids discharge diameter thus creating a Drying section at the Solids discharge end called a beach. The larger the beach the dryer the solids discharge however this will reduce the amount of liquid inside the bowl.
A larger the amount of liquid usually results in a cleaner effluent.

We can offer many different drive systems to operate decanter centrifuge form fully automatic Frequency controlled units to a simple one speed setup.

Based on your process requirements we can thus optimize your decanter selection.
