Manufacturing Method of Artificial Lightweight Aggregate Based on Sludge of Paper Mill

摘要

In the present invention, after mixing 40 to 60 parts by weight of sludge in papermaking process, 25 to 35 parts by weight of ocher (or clay), and 15-30 parts by weight of FLY-ASH, 15 to 20 weights of water After adding, kneading, extruding, cutting, passing through a rotary dryer, drying and spherical bodies, and then calcining at 1,100 to 1,200 ° C. in a continuous rotary kiln (ROTARY-KILN) for 3.0 to 5.0 hours and then cooling them. The present invention relates to a method for producing artificial light aggregates based on waste sludge of a factory.
