shaker screens

Recently one unit of mud cleaning system for offshore platform is ready for shipment. Different with normal design drilling mud cleaning system for onshore drilling, the mud cleaning system for offshore is with different features, like compact design, convenient transportation, offshore lifting frame, explosion proof standard to meet offshore drilling requirement, painting and coating to meet offshore requirement for better corrosion resistance.


The technical configuration is as below:
1) One unit of linear motion shale shaker, the discharged solids are collected by buffer box and collected by screw conveyor, which can transfer the drilling waste to cuttings box. The shale shaker are installed on the mud tank with offshore standard lifting pad, it needs to be lifted to the offshore platform frequently, the safety should be assured. All the mud tank pipelines are layout outside for convenient maintenance and operation. All the valves, fittings, flanges are all oil resistance material for longer working life. The shale shaker equipped with 2 ea Italy Oil brand vibration motor, the shaker screens are produced comply with API RP13C standard, with 3 layers stainless steel material wire mesh, composite material frame for longer working life. The shaker screens fixing method is by wedges.


2) One unit of mud cleaner (desander, desilter and shale shaker 3 in 1), the desander cone and desilter cone are all made of 100% polyurethane material for longer working life. The bottom shale shaker is same model with the shale shaker, the shaker screens are with same dimension. The shaker deck bottom are made of stainless steel material for better corrosion resistance.
3) Centrifugal pump, the pump casing and impeller such wear parts are made of ductile hard alloy for longer working life, FAG brand bearing for reliable operation. We can get offshore lifting pad certificate as per client’s requirement.

As a professional piling desander unit manufacturer in China, our desander unit has been widely used for bored piling project and TBM project in the world and domestic market. Recently we shipped 10 units of 500gpm desanding unit to Asia client. The configuration is as below:


1) 1 ea of 10 inch desander cone installed on the double deck shale shaker, the separation cut point is 40 microns.
2) The double deck shale shaker is installed on the V bottom mud tank, the feeding pump of the desander cone is installed on the mud tank as compact design.
3) No mixing hopper and mixing pump is included in the desanding unit, if the client need mud mixing unit, we will provide a separate jet mud mixer with a storage tank to connect with the desanding unit.
The working principal is as below:


1) The submersible slurry pump outside is feeding the bored piling or TBM slurry to the double deck shaker bottom screen, to separate the coarse solids from the slurry, the slurry is dropped into the mud tank, the centrifugal pump will transfer the slurry to the desander cone to separate the fine solids up to 45 microns. The double deck shale shaker can increase the treating capacity and better separation performance.
2) The clean fluids are flow to a separate mud tank for reuse, the user can connect the jet mud mixer with this tank to add chemicals and prepare for new fluids.
3) The centrifugal pump installed in the desander unit is produced by GN solids control, the pump head and all the parts are interchangeable with world famous brand centrifugal pump. The wear parts impeller, mechanical seal and pump casing is made of hard ductile iron alloy for better abrasion resistant.
If you need mud desander unit, pls contact with GN solids control.

Tandem shale shakers are shipped to Middle East Oilfield Service Company this week, the technical configuration is as below:
1) 2 single deck shale shaker installed on one tandem skid, with possem belly. When loading in the container, the single shale shaker will be packed by wooden pallet separately, the skid will be fixed by special made frame, the possem belly will be protected by plastic flim and disassembly to fit to the container size.


2) The 2 tandem shale shaker treating capacity is up to 1200gpm for drilling fluids of both WBM & OBM & SOBM. We can provide the shaker screens with API NO. from API 20 to API 325 as per clients’ requirement. The shaker screens are composite material frame shaker screens for longer working life and larger screen area. Each single shale shaker is equipped with 3pcs shaker screens for free.
3) The shaker deck bottom is made of stainless steel 304 for better corrosion resistance of the fluids touch part. The shaker skid is made of high grade structure steel. The screens are locking by the wedges for fast replacement of the shaker screens, the user do not waste much time to replace the shaker screens, and the screens working life is average 300 hours, it reduces the times to replace the screens.
4) The compact design is for convenient transportation from one rigsite to another.
We can also produce the triple shale shakers as per the client’s requirement, to install 3 units of linear motion shale shaker on one oilfield skid. The explosion proof vibration motor and starter could be CNEX, ATEX OR IEC EX for option as per the different requirement.
If you require shale shaker, mud cleaner, decanter centrifuge, vacuum degasser, pls contact with GN solids control, we can also produce customized tandem shale shaker.

GN solids control showed our equipments at Petrotech 2019 in India from Feb. 10th to Feb. 12th. The equipments we showed at the oil show in India including:


1) Sludge vacuum pump: it can be used to transfer drilling cuttings, powder cement, waste sludge, oil sludge, drilling fluids, industry waste water, mining tailings, dredging slurry, sand, even for animal waste, etc. Especially for high viscosity sticky oil sludge from refinery crude oil tank bottom, the vacuum pump is an ideal equipments to transfer the oil sludge, but the flow rate will be different with the normal flow rate. Depends on the different conditions oil sludge, we will choose the proper model for our clients according to the question list they filled.


As a 100% air operation pump, the vacuum pump do not need any electricity to operation, this is pretty convenient in some jobsites when electricity is limited, the user can use the air compressor in the jobsite to provide air for the vacuum pump, they can choose automatic operation or manually operation for their requirement.
2) Centrifugal pump: the complete centrifugal pump is consist of pump head, coupler for motor end, coupler for pump end, electric motor, control panel, skid and other accessories. The pump head is the most important components for the centrifugal pump, our pump head and all the parts are interchangeable with world famous brand centrifugal pump.
3) Shale shaker: the 2 panel shale shaker is the smallest model we have now, we have 2 panel, 3 panel and 4 panel single deck shale shaker for option, also we have dual deck shale shaker for special purpose.

GN solids control will ship 1800pcs shaker screens to our client in Asia after Chinese New Year holiday. All the screens are composite material frame shaker screens, the dimension is 635x1253mm. The screens can be loaded into 2 containers. Our factory will be closed for Chinese New Year holiday from January 29th to February 13th. Pls contact with GN solids control by email freely.
