Deinking Cell
The inner part of the Deinking Cell is divided into 4-5 layers, the single Mac Flotation Cell can make
4-5 stages flotation treatment Enclosed design, injector flush
system.
Working Principle and Performance:
· The stock is pumped and sent tangentially to the top of the cell
after being aerated by a set of small auto clean injectors. Once in
the cell, air bubbles, after collecting ink particles, rise up to
the top of the cell to create a thick foam mat which is evacuated
due to the slight pressurization of the cell.
· The stock partially de-inked goes to de-aeration chamber and is
pumped full flow to the next stage. The operation is exactly the
same as for the first stage, with the same number of injectors and
same flow.
· The operation is repeated up to five times, thus giving the best
possible ink removal under industrial conditions. Re-mixing of the
air coming from the downstream stages aids the upper stages
significantly improving the overall cell efficiency.
