In this paper, cationic poly (quaternary ammonium salt) graft copolymers were used to study the dehydration of fine coal, and the effects of flocculant dosage, molecular weight, degree of vacuum and pH value on dehydration effect were discussed. The results show that the cationic flocculant can obviously improve the technical index of fine coal filtration and dehydration. Figure 8, reference 6.
