RECYCLED FIBRE PROCESSING WORLD PULPPAPER16 Mills incorporating waste paper in their process have often struggled for a long time with many different issues. The more obvious are the actual contaminants accompanying the waste paper. However more recently the fibre properties can start to degrade as well as fluctuate more. Amongst other things this is due to less sorting and more mixing of different grades making it largely impossible for the mills to source the correct furnish. Companies spend significant extra time and money in order to secure a furnish mix that will not only give them the By Niklas Tunell Area Sales Manager NS America Cellwood Machinery AB A single approach for a multifaceted result when processing recycled fibre As the tacky contaminants reach the machine there will be downtime to handle wire felt and doctor blade changes desired end quality but also keep the production upsets to a minimum. As the tacky contaminants reach the machine there will be downtime to handle wire felt and doctor blade changes as well as cleaning. Often it will also mean a heightened reject rate of the finished product andor defects therein which lowers the value of the same. Mills also tend to have to run higher basis weights on their specific grades to meet strength targets this is mainly due to a fibre source with less physical strength and not enough installed refining capacity to correct it. The solution can be found with the KRIMA HDS Hot Dispersion System which in one single system achieves the same as a complete stock preparation and approach flow upgrade. THE KRIMA HDS Paper is a product which we all use on a daily basis. As raw material and energy prices continue to fluctuate and rise it becomes increasingly important to have the correct tools with which to handle these changes. The KRIMA Hot Dispersion is one important component Figure 1. Krima HDS Installation
