The hot dispersion system is used for handling the impurities in raw waste paper, such as hot melt material, asphalt, plastic and ink etc.
To cope with the increasing demand for waste paper stock in the paper manufacturing industry, the waste paper stock preparation machines have been developed.
Under such a circumstances, it was found that the “Hot-Dispersing” process is important. Compared to the conventional Refiners, beaters & squeezers , we would like to serve you as an adviser in improving your stock preparation and taking a new look at your production flow.
The principal task of disperser is to ensure good optical characteristics . Several processes takes place in disper-sion that lead to improving optical cleanliness. Dirt particles are removed from the mottled fibers and hence are made floatable. The floatability of existing “Free” (detached) dirt specs is improved by catching size distribution.
Also the dirt particles size reduced to below human visibility limits.beside ,bleaching chemicals are often mixed in the disperger.
