18" Oilfield Solid Control System Solid Bowl Decanter Centrifuge
Centrifuge Model LW450×1000-N for separation of detrital material of drilling muds is widely used in solid control system for drilling mud to separate the solids phase of mud, remove harmful fine drill solids such as debris, etc. in the mud fluid, or recover weighting materials such as barite etc. so as to reduce the cost of mud fluid.
Model LW450×1000-N centrifuges with line frequency control system are split into model N1, model N2 and model N3 based on the rated speed of the bowl, respectively representing the rated speed of 1800r/min, 2000r/min and 2200r/min. In addition, centrifuges with variable frequency control system are available. See Chapter 2 “Technical Parameters” for details.
Centrifuge Bowl and screw conveyor are made of stainless steel (No. 304/316) for high resistance to wearing and erosion.
XBSY Centrifuge provides solutions to all technological problems of solids-liquid and liquid-liquid separation, specialized in industrial centrifugal separation markets. These solutions help customers to clarify, concentrate, and separate products in production.
Over 400 sets are widely used in overseas market including United States,
Russia, South America, Middle Asia and Middle East. With 7 patents given including a special controller for flow ajustment.,
Screw conveyor are bonded with hard alloy blocks that improves the
service life up to 5 years..
Max through capacity up to 80 m3/h (SG<1.1)
It is a large-displacement model with high rev. and large treatment
volume developed by us and a unique model among domestic petroleum
drilling fluid-purpose centrifuges.
