High performance disc separator from Chinese leading manufacturer since 1954

The disc stack separator separates solids and one or two liquid phases from each other in one single continuous process, using extremely high centrifugal forces. When the denser solids are subjected to such forces, they are forced outwards against the rotating bowl wall, while the less dense liquid phases form concentric inner layers. The area where these two different liquid phases meet is called the interface position. This can be easily varied to ensure that separation takes place with maximum efficiency. Inserting special plates (the "disc stack") provides additional surface settling area, which dramatically speeds up the separation process. The particular configuration, shape and design of these plates enable continuous separation of a wide range of different solids from either one or two liquids. The concentrated solids phase formed by the particles can be removed continuously, intermittently or manually, depending on centrifuge type and the amount of solids involved.

Separation takes place inside a rotating bowl. The feed is introduced to the rotating centrifuge bowl from the top via a stationary inlet pipe and is accelerated in the distributor before entering the disc stack. The distributor is specially designed to ensure smooth acceleration of the feed liquid. Separation of liquid-solids takes place between the discs, with the liquid phase moving through the disc stack to the center and led to the paring chamber, where it is pumped out of the bowl by a built-in paring disc. Solids are collected in the periphery and discharged intermittently into the solids collecting cover. Solids discharge is achieved by a hydraulic system that at pre-set intervals forces the sliding piston to drop down, opening the solids ports at the bowl periphery.

The suspension to be separated is fed into the separator bowl from the top through a feeding pipe and enters the disc stack. The heavy phase and heavy sludge are forced towards the periphery of the bowl, while the light phase flows towards the center of the bowl, from where it is pumped out for further processing. The heavy phase is led over a top disc into a chamber where a paring device pumps it out of the separator. Solids collect in the sludge space and are discharged intermittently and automatically. The discharge is achieved by a hydraulic system that at preset intervals forces the sliding piston to drop down, opening the solids ports at the bowl periphery. The solids are collected in the frame and leave the centrifuge via a cyclone.

Self-cleaning disc stack centrifuge separators are typically divided into two types: purifiers for separating solids and two liquid phases in one continuous process, and clarifiers for separating solids and one liquid phase.
