Introduction of decanter centrifuge
Decanter centrifuge is the forth phase solids control equipment for
2-5 micron separate by centrifugal force at 30 cubic meters per
hour treating capacity. AIPU Solids Control supply various options
of electrical drive centrifuges with bowl size from 220mm to 550mm
size. Before centrifuge treatment, the drilling mud need to be
treated by shale shaker, desander and desilter for 15-25 microns
finally by desilter cyclone.

Working principle
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.
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.
High Speed Decanter Centrifuge
Model: APGLW 355x1258D. AP is the short name of AIPU Solids
Control. G means high speed rotating, LW means horizontal
centrifuge. 355 means centrifugal bowl diameter 355mm, 1258 means
bowl length is 1258mm.
Mud flow capacity: 35 cubic meters per hour.
Max bowl speed: 3800 RPM at separation factor 2035G.
Main drive motor size 37kw, accessorial motor size is 7.5kw. The
rotating difference between bowl and screw is 35RPM.
Electrical control panel: Fix speed electrical control panel can
make the centrifuge operating at a fixed speed bellow 3800RPM. VFD
control panel to make centrifuge frequency speed from 0 to 3800 RPM
depending on drilling conditions.
Rotating part like bowl and screw is made by stainless material
SS316L. The impeller is coated or welded by tungsten carbide alloy
Do you have any demand on centrifuges? No matter for solids
control or for drilling waste management,or for the slurry
separation and sludge treatment. Please feel free to contact us.
