GN’s decanter centrifuges are 2 phase type and mostly used in oilfield for drilling fluids fine solid particle separation and waste management as GN is known as a China leading professional manufacturer for solids control equipment for oil & gas industry. However, according to the working principle, the centrifuge should be able to be used in some other industry for liquid and solids separation just like the dredging slurry separation and construction site solids removal.
GN ever sent one solids removal system including shale shaker and decanter centrifuge to London for the construction project there. On the construction site, the worker may use water to wet or mix some construction material. Nowadays, most of the office building has parking area at the ground floor of the building. When the beginning of building, the workers will operate the rotating drilling machine to drill some holes on the ground for piling. This type of drilling will also need water for cooling down the drill bit and take out the drilling cuttings from bottom of the drilling hole.

Solids Removal Unit

GN’s solids removal system is used to separate the solids and liquid. On construction site, it will be used to remove the stone and other large size solid particles from the water. The unit sent to GN’s customer in London was a 2 phase solids control system. The configurations are as below:
1 unit shale shaker with 3-panel screens for primary solids control could remove most of the large size solid particles. The solid particles on construction site would be various from sand, stone, leaves and waste cans. The shaker could remove almost all the coarse particles by using the wire mesh screens.
1 unit decanter centrifuge with speed up to 3200 rpm is used for fine solids separation. GN’s centrifuge is made of excellent material on bowl and screw propeller for long lifetime and easy maintenance.
1 mud storage tank is divided into two compartments for sand trap under the shale shaker and clean liquid collection under the centrifuge. 2 pumps are installed on the tank skid. One of the pump transfers the slurry from sand trap compartment to the centrifuge, another one is used to transfer the liquid out from the tank for reusing.
GN’s mud tank system is with the CE certificate thus the clients from Europe could use GN’s mud system freely without worrying about the compliance. For any request, welcome contact GN for more information.
