SYSTEM FOR CONTINUOUS TREATMENT OF CELLULOSE PULPS
This system is intended for paper and cellulose manufacturing process, in order to enable partial or full talc replacement in controlling pitch and stickies, in addition to helping in retention and drainage in paper and cellulose manufacturing processes. The chemical methodology and processes employed herein primarily involve the mix of adsorbent clays such as bentonite and hydrotalcite in the form of a slurry mix, obtained through a thermodynamic equipment called continuous flow shearing chamber (502), which provides delamination in pressure and temperature conditions, able to enhance the exposure of adsorption sites.
