Cleaning systems are used to remove coarse or fine heavy and lightweight contaminants as well as entrained air. This provides a clean fiber material but also reduces wear and tear in the downstream equipment. The cleaners are used for recovered paper stock systems, approach flow systems, and stock preparation systems with virgin fibers.
To minimize fiber loss, the rejects have to be processed in subsequent cleaner stages. There are two or three cleaner stages in Voith's recovered paper systems. In the approach flow system, no more than four stages are required. :-)
