Abstract
An arrangement for cleaning a wool chamber in the manufacture of mineral wool. In the manufacture of mineral wood, a binder is added to the stream of fibres. The stream is deflected towards the wool chamber and the binder deposits itself in fine droplets on the fibres. The binder-loaded fibres which touch against the walls and roof of the wool chamber adhere to them, because the binder hardens upon contact with the hot surfaces. Gradually a hard deposit of binder and fibres is formed upon the walls. Cleaning of the walls is substantially simplified by making the walls and/or the roof of hollow, double-walled construction, perforating the inner walls, applying a reduced pressure in the cavity between the walls, and holding a detachable lining against the inner walls by suction. When the detachable lining has become coated with deposits of binder and fibres to a certain thickness, production is halted and the reduced pressure is broken off, whereon the detachable lining together with the deposits falls off and a new detachable lining is applied to the perforated walls.
