Abstract:
The present invention provides in a process for obtaining glued dried fibers suitable for the production of fiberboards, characterized by the following steps: carrying dried fibers in an air stream for the removal of high density contaminants from the dried fibers by means of gravity, and gluing said dried fibers. The invention thereto also provides a modified air density separator comprising one or more injection means for a gluing composition. The invention also relates to a fiber board manufacturing plant comprising an air density separator according to an embodiment of the invention.
