Used Flottweg Decanter Centrifuge Z6E-4
The main application of Used Flottweg Decanter Centrifuge Z6E-4/454 is to separate large amounts of solids from liquids on a continuous basis. They are also used to wash and dry various solids in industry, such as polystyrene beads, clarify liquids and concentrate solids. Table 1.0 displays various examples of the utilisation of decanter centrifuges in various industries.

Mechanical separation process
In many processes, mechanical separation has a decisive influence on product quality, production efficiency and environmental impacts. Mechanical separation processes are found in practically all industrial sectors, including, but not limited to, food, chemical, pharmaceutical, biotech, mineral, and environmental processes.
The basic principle of the solid bowl centrifuge has been known since the end of the 19th century. Over the course of time, technological improvements along with the availability of high strength and corrosion-resistant construction materials have allowed solid bowl decanters to be applied to many processes for mechanical separation of solids and liquids.
How the Decanter Centrifuge Works
The Used Flottweg Decanter Centrifuge Z6E-4 can be viewed as a settling pond wrapped around an axis. In the settling pond, solid particles that
are heavier than the liquid settle to the bottom, driven by gravity, building up a sediment layer on the bottom of the
pond. In the rotating bowl of the centrifuge, solid particles that are heavier than the liquid move to the inner diameter of
the bowl driven by centrifugal force and build up another sediment layer on the inner surface of the centrifugal bowl.
Since the centrifugal force in the decanter is approximately 3000 x g instead of 1 x g in the gravitation field, separating
solids from a liquid in a centrifuge becomes much faster and more efficient.
