Graphic papers Newsprint Corrugating medium Fig. 11: Example of a complete rejects handling system for preparing the rejects for incineration. A Dinoscreen is used for removing coarse contaminants from the sewer channel, dumping them into a separate container. Rejects from HD and LD cleaning and from slot screening are dewatered in a Sediphant. The heavyweight material from the Sediphant is also discharged into a separate container. The complete rejects from the drum pulper are collected on a conveyor. A metal detector removes large pieces of metal, which are dumped into a container by reversing the conveyor direction. A magnetic separator, located above the conveyor, removes ferrous metal, also dumping it into a container. The rejects are then shredded into small pieces in a Lion shredder. Rails allow the shredder to be moved into a maintenance position without interrupting operation of the rejects handling system. A second magnetic separator then removes any remaining ferrous metal from the conveyor feeding the post-shredding stage. Here, two Lion shredders operate one above the other and at 90° to each other.

The feed conveyor can be swung so that the post-shredding and the subsequent compactor stages can be bypassed. In normal operation the shredded material is dewatered with a Compax reject compactor, achieving a dry content of more than 60 %. After compacting, the rejects are distributed automatically into four containers. A movable conveyor equipped with sensors can fill every container from several positions so that all four container capacities are used to the full. The rejects are now suitably ready for incineration. Up to now, most of the examples of complex rejects handling systems are in Europe, but in other countries there is an increasing need to pay more attention to rejects handling. This is motivated either by the need to reduce operating personnel or to simplify disposal and make it more cost efficient.

This relationship was extended into a partnership, when the former Haindl Schongau paper mill decided to replace their PM 9 with a new modern One Platform Concept machine from Voith. As PM 9 had always been in good condition and was producing top quality newsprint paper at very high efficiency, the decision was made to sell this machine. Paper Machines Graphic wanting.zhao@voith.com The success story of Shandong Huatai Paper and Voith Paper keeps on rolling The business relationship between Huatai Paper and Voith Paper started nine years ago when Huatai began to negotiate and purchase their High Tech components for the new PM 1 of their new paper mill complex. Paper Machines Graphic bernhard.haeussler@voith.com PM 9 was completely dismantled, boxed and shipped to China to be reinstalled for its revival at Shandong Huatai Paper mill site in Dawang. A new building was erected to give home to this machine and in short time it was possible to start it back up again. With a face lift, as far as the optical appearance is concerned, and minor new Wanting Zhao Bernhard Häussler Hannes Liebscher † Paper Machines Graphic Eduard Krasser † Paper Machines Graphic Joachim Huber 15 units, the machine was completed. The dismantling as well as the erection, commissioning and start up was performed by Huatai Paper together with Voith Paper. After a picture-book push button start up good quality newsprint paper could be produced from the first day.
