Sheet and Reel Core Waste Extraction

The corrugated board manufacturing process uses reels of paper supplied by a paper mill which are formed and laminated to form the finished product. The outer wrapping of each reel of paper provides protection during transportation and handling and is removed as waste to be recycled. At the end of each reel the paperboard core again is left as waste to be recycled. These two sources of waste can be fed into appropriate types of shredder units to reduce the size of waste so that it can be transported from the reel store to the waste recycling baler using an air system, saving plant time and money in operator activities. Shredding the waste material enables the waste to be effectively baled which subsequently reduces off-site logistical costs as baled shredder waste improves the bulk density of the waste.

On the corrugator itself, at the regular order size changes, for different board sizes, a small quantity of cut sheets of finished board are ejected, as the size change takes place during the continuous production of the board. Once again, a shredder may be used to take the sheets, manually fed or from an automated system, to reduce the sheet to pieces which can be transported from the corrugator production area to the waste recycling baler using an air system, saving plant time and money in operator activities.

As the requirements or shredding waste materials are not continuous, the waste extraction system may serve more than one location or only run as required, reducing energy costs.
