Wide Range Applications of GNLW Series Decanter Centrifuges

Decanter centrifuges have been working as
very essential equipment for separation ever since it came out years ago, it is
widely used in many industries, including the food industry, chemical industry,
pharmacy industry and oil and gas industries.

Divided by the types, the decanter
centrifuges could be defined as horizontal decanter centrifuge and vertical
decanter centrifuges. The working principles are same that by using the different
centrifugal forces laid on the different size materials, a certain sized
particles are separated out. In oil and gas industry, horizontal decanter
centrifuges are commonly used while they use Vertical Cuttings Dryers in front
of the horizontal decanter centrifuges. GNLW series decanter centrifuges covers
all necessary sizes and applications used for oil and gas drilling, such
applications including following

GN Decanter Centrifuge Familiy: 

1. GNLW452, 18 inch diameter of bowl, big
bowl centrifuge, middle speed. suitable for solids control application in oil
and gas drilling, especially for barite recovery. Barite is heavy and expensive
drilling material in the drilling liquid and could be suitable for re-use if it
is well recovered. This model of GNLW Centrifuge is normally fixed speed as
standard configuration, but it still has 3 optional speeds by changing the
pulleys and belts

2. GNLW363, 14 inch diameter of bowl, most
popular size in oil and gas drilling, high speed up to 3900RPM, it provides the
most applications among all GNLW centrifuge models, in case of fixed speed
GNLW363, GN designed 3 optional speeds based on the experiences in previous
projects, and end user could choose via using different pulley and belts. In case
of VFD controlled, GN also have 2 optional VFD control panel for option, the
speed could be set from 0 rpm to 3200 rpm.

3. GNLW453-VFD decanter centrifuge, 18 inch
bowl diameter big bowl centrifuge, with larger length diameter ratio as above
mentioned GNLW452, higher speed and for extra fine particles comparing with
GNLW452, but with larger treating capacity than GNLW363.

4. Big big bowl centrifuge GNLW553C-VFD
with 22 inch bowl diameter, which is no doubt a big guy in centrifuge family,
and GNLW223 decanter centrifuge with only 9 inch bowl and a very high speed,
which is a baby member in GNLW centrifuge family.
