3 Package Hydraulic Drive Mini Centrifuge Unit for Diamond Core Drilling

3 package of hydraulic drive mini centrifuge unit are shipping to diamond core drilling.
The key features of GN hydraulic drive mini centrifuge unit including:
1. Drive system: Hydraulic motor powered by a diesel engine, compared with electrical motor drived centrifuge, the hydraulic drive centrifuge system can be applied in remote area where electricity power is limited, and the hydraulic drive system can provide high torque and variable speed control to handle fluctuating loads.


2. Design and portability: GN hydraulic mini centrifuge system adopts a modular design and lightweight to meet the requirements for helicopter hoisting. The skid modular design is for easy installation and disassembly, easy to relocate and set up on confined drill pads.
3. Separation performance: The system is a complete mechanical separation without adding chemicals to reduce the chemical cost, it can improve the performance of drilling fluids and enhancing drilling efficiency. The high G force decanter centrifuge can generates 2492G to remove ultra-fine solids down to 2-5 microns; maintains stable mud properties, reduces bit wear, and improves core sample quality.
4. System components: The hydraulic drive centrifuge system including mini hydraulic centrifuge, hydraulic drive system, diesel engine, mud tank, feeding pump, mixing pump, mixing hopper, it forms a complete, closed-loop mud recycling system; allows for immediate reuse of treated water
Why should we use the hydraulic drive centrifuge system?


(1) Operational Independence: It completely removes the dependency on unreliable or non-existent local power grids, ensuring operations can continue uninterrupted in the world’s most remote locations .
(2)Environmental Compliance: By recycling water and drastically reducing the volume of drilling waste, it helps drilling companies meet stringent modern environmental standards and reduce their overall ecological footprint .
(3) Cost Efficiency: Lower water consumption, reduced chemical usage, less waste transportation, and decreased wear on drill bits and pumps all contribute to significant project savings .
(4)Enhanced Drilling Performance: Maintaining consistently clean mud improves the rate of penetration, extends the life of downhole tools, and most importantly, enhances the quality of the core sample retrieved

16 Packages GN Solids Control Centrifuge for Offshore Drilling Company

Recently 16 packages of GN solids control centrifuges are shipped to offshore drilling company, this is the repeat order from this client.


The offshore decanter centrifuge package including one centrifuge with feed pump and solids discharge trough, one offshore skid, one fluids catching tank and transfer pump, one offshore used VFD control panel. All of the equipments are installed as compact unit for offshore application, the skid and decanter centrifuge lifting pad is designed comply with DNV 2.7-1 standard.
The decanter centrifuge motor and VFD control panel is adopted with offshore applied explosion proof standard. The ambient temperature to be used is -20℃ to +55℃.The standard atmospheric pressure is 80 Kp to 110Kp, normal oxygen content 21%, it can be used with altitude <1000m, relative humidity less than 95%. One centrifuge is composed of main bowl assembly, power drive system, feeding and discharge device and electrical control system.


The decanter centrifuge is widely used in the solids control and drilling waste treatment project, it works to separate the solids phase from drilling fluids, remove the harmful fine drilling solids such as debris in the drilling mud, or recover weighting materials such as barite , etc. as to save the drilling fluids cost. The decanter centrifuge can be used for both onshore and offshore projects, but the electric motor, control panel including VFD control panel, cables standard are different.
GN solids control can produce 9 inch bowl centrifuge, 14 inch bowl centrifuge, 18 inch bowl centrifuge, 22 inch bowl centrifuge, 30 inch bowl centrifuge, each size decanter centrifuge provides 2 models as rated frequency and variable frequency drive. Except for 2 phase decanter centrifuge, we also produce three phase decanter centrifuge to separate oil, solids and water for oily waste water treatment.
If you need a decanter centrifuge package, pls contact with GN solids control.

GN Decanter Centrifuge and Cuttings Dryer for Africa Drilling Company

One set of GN decanter centrifuge and vertical cuttings dryer are using for Africa drilling company. The equipments list including:
2 units of decanter centrifuge，model GNLW363D-VFD
1 unit of vertical cuttings dryer，model GNCD930G
Matched with screw conveyor, centrifuge feeding pump and vertical cuttings dryer flushing pump.


The screw conveyor GN produced including 10 inch, 12 inch, 14 inch, 16 inch and 18 inch diameter for option, each section standard length is 12 ft, we can use different quantity sections as per client’s requirement of transfer length, such as 12 ft, 24 ft, 36 ft, 48 ft, 2 sections are connected by pin shaft hanger. The screw conveyor can be fixed speed or variable speed( manually speed adjustable) to control the feeding rate. The screw propeller material is High Chrome Alloy Steel for longer working life.


According to the installation position and function of the screw conveyor, there are auger system for primary shale shaker discharge solids collection, desander desilter discharged solids collection, feeding to vertical cuttings dryer feed hopper, solids discharge auger for vertical cuttings dryer, solids discharge auger for decanter centrifuge, etc. The protection cover on the U type reinforcing beam could be closed steel plate or steel grating for option.
Additional safety protection of the screw conveyor:
1) Pull chord emergency stop with wire rope to be provided along the length of Augur for Emergency stop；
2) Audio / visual alarm system on the auger control panel which will be automatically activated once the power is switched on followed by the actual auger startup with a safety delay time. Audio / visual alarm system to be in the OFF mode after some time once the auger starts operation.

GN Decanter Centrifuge System for Africa Oilfield Waste Water Treatment

Recently one set of GN decanter centrifuge separation system are ready for shipment to Africa oilfield waste water treatment project. The system including mixing module, decanter centrifuge separation module, chemical dosing unit module, water recovery and transfer module.


The mixing module including mixing tank with mud agitator, to mix the oilfield waste water, the decanter centrifuge feeding pump will suck the water from the mixing tank to decanter centrifuge, at the same time, the chemical dosing unit will prepare the mixed chemicals and the screw pump will transfer the chemicals to centrifuge feed tube, so the decanter centrifuge can treat the waste water better, the treated water will flow to the water recovery tank and will be transferred to other tanks by the transfer pump.


The decanter centrifuge can separate the waste water into solids phase and liquid phase, GN also produce three phase decanter centrifuge, to separate the waster water into oil, water and solids. A three phase decanter centrifuge uses continuous high G centrifugal force to separate components based on density differential. The three-phase separation (solids, water, oil) happens because:
Solids (highest density) move to the bowl wall.
Water (middle density) forms an intermediate layer.
Oil (lowest density) forms an inner layer (if present in sufficient quantity).

GN decanter centrifuge features including:
1. The bowl and screw core shaft are made of duplex stainless steel SS2205 or SS2304 by centrifugal casting, which is superior to the performance of SS304 and SS316;
2. The solids outlet and liquid outlet are protected by replaceable hard alloy sleeve.
3. The main material of the screw is duplex stainless steel SS2205 or SS2304.
4. The screw propeller is protected by tungsten carbide tiles for longer working life.
