GN Solids Control has provided thousands of mud treatment systems to world wide clients. Lately, we finished the manufacturing of another HDD mud treatment decanter centrifuge for a China Engineering company. 

2021.04.24 Dewatering Decanter Centrifuge

It is a trend that more and more contractors are using decanter centrifuges to treat HDD mud. Before most of HDD mud was only treated by mud recycling system, which includes shaker or 4 inch/10 inch hydro cyclones. It is for sure that shaker mud recycling system help to remove solids larger than 25 microns, while with time goes by, more and more small particles accumulated in the drilling mud which will bring harm to the HDD rig: low working efficiency, fast weariness of drilling pipes. Thus use a decanter centrifuge is become necessary. 
As for this China Engineering Company, GN Solids Control provides one 22 inch bowl decanter centrifuge GNLW553C-VFD and one chemical dosing unit. 
GN decanter centrifuge is made of duplex stainless steel 2205 or 2304 by centrifugal casting which guarantee good working dynamic balance under high rotating speed. Screw propeller inside the rotating bowl is also protected with bolted tungsten carbide tiles or spraying coating to guarantee a long time working without changing those parts face solids.

One variable speed control box is equipped with the decanter centrifuge. GN experienced engineers build the software and construct the hardware, it makes us much easier to provide a tailored control system based on clients’ demands. All key working parameters can be set easily on HMI screen. 
In order to remove finer particles, GN Solids Control also provides one chemical dosing unit with the decanter centrifuge. Flocculant helps small particles united stronger, so the decanter centrifuge can eliminate them. 
GN Solids Control also manufactures some other types of solids and liquid equipment, such as dewatering screw press, inclined plate clarifier, vibrating screen etc. Welcome to connect with GN for the most cost-effective solutions.
