Decanter centrifuges are used in separation of solid-liquid or solid-liquid-liquid suspensions. The machine consists of a solid cylindrical bowl rotating at high speed, a scroll rotating in the same axis with a slightly different speed, gear box adjusting the speed difference and the body which carries all the rotating elements. The product is fed along the centre line to a fixed distribution room within the bowl and then accelerated into the bowl by centrifugal force through the feeding point. This centrifugal force then causes the suspended solids (the cake) to settle and accumulate at the bowl wall. The cake is discharged by scroll from the conical part meanwhile clarified solids and water or only liquid flows back along the bowl and is discharged through the cylindrical end of the bowl by plates which can adjust the level of liquids.
All parts in contact with the product are made of stainless-steel. Moreover, in order to establish maximum security, all bowl parts are manufactured with centrifugal casting method. Thus, a weldless bowl part with homogenous micro structure and without micro crack faults is produced.
Separators are designed to clarify the liquid in liquid-solid mixture or for liquid-liquid separation in the liquid-liquid-solid mixtures. General principle is providing the solids extraction from the environment continuously and fast, by mechanically separating different liquid and solid phases in order to meet the need of modern industrial processes.
A separator consists of a bowl group rotating at high speeds, the drive elements that drive the bowl and the body that carries the bowl and drive components.
The separator continuously separates a solid and liquid or two liquid phase in a single stage by using high centrifugal force. Separator, by utilizing high centrifugal force, separates a solid and one or two liquid phases from each other continuously. As solids having higher density than liquids are pushed against the inner wall of the bowl and precipitated, the liquids having less density forms coaxial inner layers. The point that these two phases come across is called interface. This interface can be easily changed to get the best result.
All the parts in contact with the product are made of stainless steel.
