Well Drilling Mud Decanter Centrifuge For Solids Control

Product Specification

Zero Discharge Mud Decanter Centrifuges For Well Drilling Solids Control System

Summary of decanter centrifuge

Decanter centrifuge is 4th solids control equipment or 5th purification equipment. Including middle speed and high speed centrifuge.It is used after desilter or mud cleaner. We use submersible slurry pump or screw pump to transfer drilling mud from desilter compartment to centrifuge

Centrifuges used in zero discharge mud system is to get rid of rather little solid in drilling fluid. To maximize drilling fluid liquid content recirculation and minimize solid disposal

Compared to previous solids control equipment, centrifuge remove fine cuttings or recycle barite with 2~7 microns diameter. The material for centrifuge including S.S304, 316, 316L, 2205, and so on. Per clients' demand and their budget we'll configure different products

Decanter centrifuge is the 4th solids control equipment in whole drilling mud system It is used to process drilling mud discharged from desilter cones or mud cleaner

3. Screw flow distribution port and bowl solids discharge port protected by tungsten carbide alloy.
4. Easy to adjust liquid discharge weir height for flexible application.
5. Bowl assembly supported by the tighter belt for the protection of bearing in moving.
6. Pressurized EX Proof VFD control cabinet available.
7. Genuine SKF bearing for longer and reliable operation.

Working principle of drilling mud decanter centrifuge

The working principle of horizontal screw centrifuge is very simple. It has been known by the public for a century. The drum and screw are supported by separate suspension.The material enters through the inlet pipe and accelerates into the core drum body through the drum.

How to select decanter centrifuge for fluids system?

Mudflow: The flow rate is related to bowl size and rotation speed.
Industry: Use it in oil drilling, water drilling or HDD?
Depth: Drilling depth is another issue considered during selection. Usually, depth over 3500m, the high-speed one should be utilized.
Drilling fluid property: Viscosity, mud base, and so on. Kindly confirm the applicability from mud engineer or centrifuge supplier.
Function to achieve: Separation, or recycle?

Decanter Centrifuge Main Component

Rotating parts including centrifuge bowl and screw for stainless steel material. Screw impeller is coated with tungsten carbide for protection of impeller wear. The most popular size bowl is 355mm diameter and 1250mm length for maximum rotating speed 3500RPM.

Main motor and assistant motor installed to drive centrifuge bowl and screw for flame proof standard.

Electrical control panel is same explosion proof standard compares with centrifuge motor. VFD control panel can be supplied for various speed control depending on mud conditions.

Centrifuge skid with legs to install bowl, motor and control panel.

Other than decanter centrifuge, AIPU is able to supply a complete solids control equipment and tank equipment like centrifugal pump, mud agitator, mud gun and degasser. The whole tank design and pipeline arrangement is customized as per request.
