Reject Drums

Johnson Screens reject drums are used to separate fibers from light weight pulper rejects. Reject is transported by means of helicoidally arranged blades inside the screen drum basket. An external and internal jet wash system is used to keep the slots or holes clean and improve the separation of fibers and rejects.

The design of the drum, in-feed arrangement, vanes and wash system are optimized for every process and raw material separately. The recovered fibers are collected in the vat under the drum and rejects are discharged at the end of the drum. The drum is horizontal or slightly inclined, depending on needed retention time.
