Decanter Centrifuge can be used in many applications, like solids control system for oil drilling, mud treatment unit for sludge treatment and also can be used for water/oily waste treatment.  In order to make the centrifuge easy to lift and transport, the customer prefer to protection framework decanter centrifuge with VFD control panel and feed pump.

GN Solids Control just got Purchase Order of protection framework decanter centrifuge from drilling sludge treatment customer. After discussion, the customer confirm on high speed decanter centrifuge GNLW363BG-VFD with Netzsch brand NEMO pump for feeding & Variable Frequency Drive PLC control panel. Pls find details as below:

GN TBM Slurry separation equipment are optimally adapted to the requirements of the tunnelling (TBM) process and separate the drilling suspension completely from the solid particles consisting of gravel, stone and sand in various grain sizes. A powerful combination different solids control equipment of state-of-the-art shale shaker technology and Hydro cyclones with high g-forces results in deposit able excavated material.

GN Solids control manufacture all major solids control equipment for the TBM Slurry separation system including following:


  • TBM Slurry separation Shale Shakers for coarse solids separation.
  • TBM Slurry separation desander and desilters for desanding and desilting separation.
  • Centrifugal slurry pump for feeding to the separation equipment.
  • Mixing hoppers for bentonite mud mixing.

Slurry handling system is also solid liquid separation system, while it usually refered in agriculture, dredger and other small projects.

Scraper are usually used for separation works, not always the shale shaker. And the working priciple is also a little different.

Shale shaker is widely used in slurry handling system.

Agitators are also used for mix up the slurry and keep the slurry active.

Slurry recycling is also very important in tunneling boring, piling, and so on. Equipments used in slurry treatment plant to keep the charactor of the slurry for recycling use.

These are a few sketchs for the TBM (tunneling boring machine) system. And as we can find, shker, desilter hydrocyclones are used in the slurry recycling, i.e. slurry treatment plant.
