<p>The invention concerns a method of processing recycled paper which contains so much wax, hot melts or stickies that they would be expected to cause a stoppage of the paper-manufacturing machine, the paper to be recycled being pulped in a pulper and passed on to a subsequent stage which includes despeckers, graders and cleaners hydrocyclones. The invention is characterized in that pulping takes place at a temperature of at least 60 DEG C, at the same time subjecting the paper to a high shear action, and that the processing line includes a pulp-thickening stage, preferably after the processing stages mentioned, in order to separate off most or a very high proportion of the wax, hot melts and stickies finely dispersed in the pulper.</p> |
