Abrasive production , chemical processing , micronized grading process , the flocculation and sedimentation technology , a careful study of the factors that affect the settling velocity , the effects of pH , slurry concentration , the reagent amount ( concentration) , temperature , process operation and other factors , to get the best sedimentation conditions . And water recycling , environmental protection , and so do the appropriate research . The Act also compared with traditional the abrasive chemical treatment , the settlement process of the micronized grading , and focus compared a the finer abrasive processing and fine Liaoduo Powder grading settlement . The results show that , flocculation and sedimentation technique can improve the settling velocity of more than 10 times , improve production efficiency more than doubled , the abrasive loss reduced by 80 % , and water recycling and reduce environmental pollution . From molecular adsorption theory , the electric double layer theory , colloid chemistry theory analysis of the mechanism of flocculation and sedimentation . According to the the abrasive production features and product requirements , preferably the appropriate additives , and their mechanism of action , research and analysis . The test results show that the use of polymer flocculant A, the inorganic coagulant B , the ζ- potential adjustment agent C , etc. , without affecting the quality of products, but also to achieve satisfactory flocculation settling results .
