<p><P>PROBLEM TO BE SOLVED: To provide a method for producing regenerated particles, capable of stably producing the regenerated particles equipped with necessary characters as a filler for papermaking or as a coating pigment, and preventing the coagulation of burnt materials and achieving the stabilization of production and uniformization of the regenerated particles in obtaining water solution-dispersed materials (slurry) of the burnt materials discharged from a burning process. <P>SOLUTION: This method for producing the regenerated particles using papermaking sludge formed in a papermaking process, as a main raw material and passing through the processes of dehydration, drying, burning and crushing in this order has the steps of incorporating calcium sulfate to the burnt materials discharged from the burning process before contributing to the crushing process. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
