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.


If you need decanter centrifuge, vertical cuttings dryer, feeding pump, screw conveyor, pls contact with GN solids control.

GNLW454GT Mud Dewatering Centrifuge for Hydrovac Slurry Treatment

One set of GNLW454GT mud dewatering centrifuge package are ready for shipment to Hydrovac slurry treatment project.


GNLW454GT Decanter centrifuge technical specification is as below:
The bowl diameter is 450mm, the bowl length is 1890mm, the length/ diameter ratio is 4.2.The max bowl speed is 3452rpm, the max G force is up to 3000G. The main motor is 37KW / 45KW/ 55KW, the back drive motor is 11KW/ 15KW/ 22KW, the beach angle is 8.5 degree, The bowl main material is made of duplex stainless steel SS2205 by centrifugal casting, the screw material is made of duplex stainless steel SS2205, the screw is protected by tungsten carbide tiles, and the centrifuge is drived by positive pressurized VFD control panel with PLC touch screen and HMI interface. The bearing is premium SKF bearing for reliable and longer working life. The T series decanter centrifuge is mainly used for dewatering unit.


GN solids control design and manufacture waste management for hydrovac slurry treatment system. The working principal is to use solids liquid separation equipment to treat the slurry from vacuum truck of hydrovac project. The slurry is contaminant free which is from physical utility location in public right of ways, and directional drilling for replacement of underground pipes and construction.


A complete hydrovav slurry treatment system including waste catch hopper, coarse solids separation shaker with fluids catching tank, Fine mesh shaker , desilter and mud tank, dewatering decanter centrifuge and chemical dosing unit with centrifuge dewatering tank or telescopic skid. The decanter centrifuge and VFD control panel and feeding pump are all installed on the telescopic skid with fluids collection tank and a transfer pump.
Except for T series decanter centrifuge, GN also produce fully hydraulic drive decanter centrifuge, Y series separation decanter centrifuge, C series clarifying decanter centrifuge and three phase decanter centrifuge.

IECEX Explosion Proof VFD Decanter Centrifuge for Middle East Client

2 Sets GNOST-15 Oil Sludge Treatment System for Asia Customer

Recently 2 sets of GNOST-15 Oil Sludge Treatment System are ready for shipment to Asia customer. Each set of GNOST-15 Oil Sludge Treatment System including the components as below:


1. Feeding pump module, to pick up the oil sludge from waste pit and transfer to pre-mixing tank
2. Pre-mixing tank module, the function is to diluting, washing, heating and mixing of the oil sludge, so that the solids can be separated from the liquids in the further process of shale shaker, decanter centrifuge and three phase decanter centrifuge.


3. Coarse shale shaker separation module, to separate the coarse solids and reduce the solids content of the oil sludge, to protect the further decanter centrifuge, if the solids content is very high, the decanter centrifuge screw will be damaged and blocked easily.
4. GNLW-554 two phase decanter centrifuge module, the fine solids can be separated out from the decanter centrifuge by adding chemicals by chemical dosing unit
5. GNLWS-554 three phase separation decanter centrifuge module, to separate the fine solids, water and oil. The recovered oil can be reused or to be sold, the water can be reused in the circulation system or sent to waste water treatment facility, the solids discharged from shale shaker, two phase decanter centrifuge and three phase decanter centrifuge will be collected and sent to TDU for final treatment.


6. Chemical dosing unit module, to add chemicals in pre-mixing tank and 2 phase decanter centrifuge to improve the separation efficiency
7. Steam generator module, to provide hot steam to pre-mixing tank heating line , shale shaker separation tank module heating line, two phase decanter centrifuge tank heating line. There are electrical driven steam generator and diesel driven steam generator for option.
