Decanter centrifuge is one of the most efficient equipment for physical separation. As long as the solids phase material are settleable (instead of floating on liquid surface), and they are of suitable particle sizes, they could be separated out by centrifugal force easily.

The decanter centrifuges are widely used for various applications, such as food industry, like the juice factory or jam factory, for the sugar plants, edible oil separation and etc. Waste water separation is one of the applications, too. Also the oil and gas industry, for the solids control system, barite recovery, drilling cuttings waste management and drilling fluids recovery, and also, for the refinery plants’ oily sludge separation, decanter centrifuges are playing an important role. In power plants, decanter centrifuges are also quite essential. Just recently, for only 1 client’s 1 order, GN has supplied 5 sets of decanter centrifuges which are to be used in a power plant.

There are several factors affecting the separation performance of a decanter centrifuge, and by adjusting the input data, a VFD centrifuge could achieve different separating goals. Normally, the larger bowl length-diameter ratio is, the dryer separated solids phase will be. GNLW454EY is a big bowl centrifuge with 18 inch bowl diameter and 4 of bowl length-diameter ratio. It is a quite ideal choice for power plant use. GNLW454EY also has a special cone angle and a high speed for such projects.

Based on different applications, GN Solids Control has designed a wide range of decanter centrifuges, more than solids control or waste management’s use. Like the bowl diameter, there are 9 inch bowl centrifuges, 14 inch bowl centrifuges, 18 inch bowl centrifuges, 22 inch bowl centrifuges and also as big as 30 inch bowl. For each bowl size, there are 2 or 3 optional length for different length-diamter ratio. And bowl material are of Duplex stainless steel like SS2304.
