Solids control is one of the main jobs where GN’s centrifuge could be used. Now the latest design of GN decanter centrifuge is the C version with premier configuration.
By the end of this year, 2 of GN premier decanter centrifuge caught up the last ship to Latin America for the solids control job there. Below are the main features of this premier model.
- High level material used for the rotating parts. The bowl is the core part of the centrifuge unit; the separation is process when the bowl is rotating. GN uses duplex stainless steel 2205 to make the bowl with centrifugal casting technology. The evenly material distribution ensures the excellent balance performance when rotating. Inside the bowl the scroll is made of SS316L which is much better than the other China suppliers who are using SS304.
- All around protection is put on the parts that will bear a lasting friction coming from the solids. The scroll is protected by 4mm thick tungsten carbide tiles that are replaceable for longer lifetime. The outlet port of liquid speeding up cone on the scroll is covered with ceramic liner. The same ceramic liner is also installed at the solids discharge port on the bowl. To prevent the building up of solids in the collection box, the tungsten material scrapers are fixed on the bowl to protect the bowl from wearing.
- To ensure the treating capacity, GN makes the slurry feeding direction and solids delivery direction same. This will speed up the solids delivering in the bowl. On the scroll blade, there are several openings allow the liquid passing through for large flow rate.
GN premier decanter centrifuge is also widely used in waste management like the waste cuttings treatment and the oily sludge recovery project. For safety consideration, GN premier decanter centrifuge is equipped with DNV lifting certified skid for transportation.
