CLEANERS / FIBERIZERS / SCREENS
The mixture, consisting of paper pulp + chemicals + inks + small debris is passed to the first
of a series of Cleaners/Fiberizers/Screens. Many different designs are on the market under
various titles e.g. Turbo Separator, Cyclone Cleaner, Combisorter, Fiberizer.
A typical view of a Turbo separator, Fiberizer and Cyclone Cleaner is shown below. As can be
seen (in the Turbo Separator) the fibre mixture is pumped (forced) through the Separator
Backplate whilst at the same time centrifuging the heavier components towards the reject
outlet. This combination of centrifugal force and some form of screen barrier is extremely
common in the design of most Cleaners/Fiberizers/Screens. Also a common feature of this
machine type is the ability to adjust the rotor position to account for wear. This sometimes
requires the use of CMAX format seals (axial displacement seals).
The Cyclone Cleaner combines the principle of a centrifugal screen with a hydrocyclone. The
feed into the screen is tangential, heavy rejects fall under gravity to the bottom outlet, fibre is
centrifuged through the perforated basket and lightweight rejects exit from the top of the
cleaner.
