After grinding mill, need dewater the solids, with strong acid. That was the situation we had, then cooperated with client, we worked together to find a solution. For shale shaker feeding, we choose vertical Netzsch pump, after the shale shaker, the fluids to a small intermediate tank, sucked by a horizontal Netzsch pump, feeding to the GN decanter centrifuge.To achieve higher capacity, and higher G force, this time we choose a 18in decanter centrifuge, which is GNLW453, with varible speed, the model: GNLW453-VFD, this model is equipped with a variable frequency control panel to realize the different rotary speed. By adjusting the speed, feeding rate, liquid level inner the bowl, the operator could adjust dryness of the discharged solids and clarity of the effluence. The shaker and decanter centrifuge need to be seated on a mud tank so that the liquid discharged could be collected properly. The tank is divided into 2 compartments for collect the effluence respectively from shaker and centrifuge. A mono pump is also fixed on the tank skid for transferring the sludge from tank #1 to centrifuge for further process. For this system, GN have required the materil from Vietnam to the real testing inside factory, before shipment, doing which to make sure the result is as expected. Before getting into this separation system, the operator would have a pit to collect the flushing sludge and then use a pump transfer to the shaker unit. GN’s equipment are widely used in many industries for solids and liquid separation like drilling fluids recycling, dredging slurry separation, crude oil storage tank bottom flushing water recycling etc. Welcome different applications wherever need solid / liquid separation, GN is ready to help.

GN just finished the fabrication of a batch of solids control equipment for 3 sets oil rig. This order is for a Europe client, and soon later all the equipment would be shipped out. This order includes 3 types main solids control equipment, shale shaker, mud cleaner and decanter centrifuge. GN has upgraded the equipment design few times, below some features on the equipment will make clear why customer choose GN.
For clients far away from China, especially the drill rig manufacture, or packager, normally have the ability to design / manufacture the mud tanks, though it is not just a steel box, comparing other stuff in the whole rig system, it is not so complicate, it is not always economic comparing to high sea freight rate by bulk shipment, and the shipping time is not well scheduled.
Shale Shaker – the shale shaker in this order is used to be the primary shaker in the oil rig mud recycling system. It has 4 panels shaker screenwith each size of 585x1165mm, total screen area 2.7 square meters. At both sides of the shaker, bolted type shaker deck fixing design make it easy for avoiding the shaker deck vibration during transportation. The horizontal beams on both sides of the deck walls make the shaker deck much stronger to bear higher G force. Screen support frame is made of stainless steel for anti corrosion purpose. The embedded hollow rubber seals on screen frame perform a good sealing function and easy for replacement.
Mud Cleaner – GN suggests in the same mud system to use same model shaker as mud cleaner under drying shaker. It would be good for future maintenance and screen ordering from supplier. GN mud cleaner adopts full PU material hydro cyclone for long lifetime, and the cyclone manifold is removable easy transportation. All GN’s shaker has the installation points for quickly fixing the cyclone manifold.
Decanter Centrifuge– both of the bowl and screw is made of stainless steel, the bowl even SS2205 or SS2304, much better than SS316. On protection of the wet touching parts, GN use tungsten carbide tiles for screw and ceramic insert ring for solids discharge port. GN processes 3-stage balancing to maximize the balance of the centrifuge include 1800RPM low speed balancing and real operation high speed balancing as well as the assembly balancing.

Not like a culture that we all been educated, it is a life, a family life, hard working with family members, and enjoy the life time, which you spent more than 1/3 of your life on. As my personal point of view, as a family is the highest recommendation on teamwork. Every year, GN will set up special fund for award of staff that made outstanding contribution to the company.
