HIGH-SPEED VFD DECANTERCENTRIFUGE

Special designed fordrilling waste management with superior high G force and high speed forseparate the fine solids (≥2μm);

Speed ranging from 0 to3900 and generate centrifugal force of 3000G;

High speed variablefrequency centrifuge with its unique advantages;

Longer bowl, offers bigvolume, generates High-G force, slow the drilling fluids, much drier and finerseparation point occur

Stainless steel bowl,scroll, compartment are available and covered with corrosion-proof coating soas to have longer lifespan;

German FAG or SwedishSKF brand bearings are available;

Electrical Componentscomplies with SIEMENS/Schneider ATEX or IEC Ex.

Screw pump and submersible slurry pump areprovided for centrifuge liquid feeding for various customers.

VERTICAL CUTTING DRYER 

·         Also called vertical centrifuges, widely used in oilfielddrilling waste recycling processing;

·         VCD can reach the performance of oil on the cuttings (OOC) tobe 3 % ~5% to meet the requirements of environmental protection;

·         Capacity up to be 50 tons per hour;

·         Especially for drying oil-based and compound-base drillingcuttings mud, also water-based drilling fluid

·         Drying drilling solids from oil or synthetic base fluids bycentrifugal force;

·         A stainless steel screen bowl traps “wet” solids and acceleratesthem up to 900 RPM and 420G;

·         Tungsten carbide protects the flights from abrasive solidsand ensures long operational life;

·         Strict balance testing for all major rotary components tominimize vibration & noisy;

·         With individual oil lubrication system with automatic alarmfor pressure limit. The main motor and oil pump motor is interlocked with eachother for avoiding the start of the main motor prior to the start of the oilpump motor;

·         Screw conveyor equipped on the discharge for transporting thedry cuttings;

·         Equipped brand screw pump for dryer cuttings cleaning.
