Specifications

1.Decanter Centrifuge
The SPRING Brand Decanter Centrifuges are for oilfield drilling-mud and fluids-handling applications. Ruggedly built for oilfield and industrial service, it is especially effective in environmentally sensitive areas. It delivers high fluid-recovery rates and efficient solids control to significantly reduce the costs of make-up fluids and disposal. This highly efficient decanting centrifuge recovers up to 95% of barite and returns it to the active system, while rejecting finer ,low-gravity solids. The advanced design of the stainless steel bowl and scroll maintains an even layer of conveyed solids for more uniform separation and maximum solids-control efficiency.
2.How it works
The heart of an centrifuge is its high-speed, precision-balanced rotating stainless-steel bowl. Inside the bowl, adouble-lead spiral screw conveyor rotates in the same direction as the bowl but at a slightly slower RPM. Feed slurry enters through a hollow axle at the narrow end and is distributed to the bowl. Centrifugal force as high as 815 G's at 1,800 RPM (or higher G's at bigger RPM) holds the slurry against the bowl wall in a " pool."  Trapped silt and sand-sized particles settle and spread against the bowl wall where they are conveyed to the solids underflow discharge ports by tungsten-carbide-tipped scroll flights. Silt and sand particles exit damp, but with no free liquid. The free-liquid phase carries the fine, 2 to 7 micron-size particles through the non-plugging stainless steel and tungsten-carbide hard-faced discharge ports.
3.Applications of SPRING Brand centrifuges
Oil & gas well drilling ---solids control system
Horizontal directional drilling (HDD) & Shield tunnelling---slurry circulating system
Mining & Environment---mud cleaning system
Coal bed methane (CBM) & Geothermal well drilling---fluids cleaning system
Dehydration, concentration, classification clarify of sewage, sludge, wastewater, starch, soybeans, wheat protein,
fishmeal, juice, Vegetable oil, coal tar, Kaolin, graphite, dyes, pigments, floating coal, and so on.
Solid-liquid separation of volatile materials, dust purification, inflammable and explosive places.
4.Features of SPRING Brand centrifuges
Precision balanced scroll to run at high RPMs for extended periods with greater efficiency, minimizing maintenance and downtime.
Continuous feeding and continuous discharging. Recovers up to 95% of barite, rejects finer, low-gravity solids from drilling fluids,
minimizing costly additions while maintaining prescribed mud weights.
Innovative design includes longer bowl for increased retention time, resulting in drier solids and finer cut points. Ideal for use with
weighted or unweighted mud systems.
Tungsten carbide scroll points with wide spacing flights at tapered end create a finer layer of conveyed solids for consistent, uniform
separation and maximum solids-control efficiency under high G-forces.
Screw conveyor flights tiled or lined with ceramic, tungsten carbide, or other hard alloys.Stainless steel bowl, scroll, compartment and cover resist corrosion and provide long service life.Skid mounted, low profile minimizes space requirements.Optional planetary gearbox and hydraulic gearbox, offering wide range of differential speed adjustment.German FAG or Sweden SKF Brand Bearings.Electrical Components: SIEMENS/Schneider ATEX or IEC Ex for option.Operating safety controls include self-limiting vibration and torque switches to protect against catastrophic failure.
Effectively removes the finest silts and returns valuable fluids for reuse, reduces makeup fluids, dilution, clean up and disposal costs.
Rugged construction and corrosion-resistant materials provide long service life and low maintenance costs in the toughest oilfield environments.
Ideal for any solids-control application; especially valuable in environmentally sensitive areas.
