Cleaning systems are used to remove coarse or fine and lightweight contaminants as well as entrained air.
This provides a clean fiber material but also reduces wear and tear on the downstream equipment. Cleaners are used for recovered paper stock systems, approach flow systems, and stock preparation systems with virgin/Recycled fibers.
To minimize fiber loss, the rejects have to be processed in subsequent cleaner stages. In Hema’s cleaner systems, in most cases two or three cleaner stages are required but not more than four stages.
