To enhance the filtration and dewatering performance while reducing the moisture content of coal preparation products, we conducted an investigation into the dehydration efficacy of various coal preparation products using different filter aids. The study involved examining the dehydration effects of both conventional filter aids and new filter aids on flotation cleaned coal and coarse fine slime at the Huaibei Linhuan coal preparation plant. Our findings revealed a significantly superior dehydration performance of the new filter aids compared to conventional hydrophobic ones. Subsequently, we explored the dehydration efficacy of a specific new filter aid, designated as 1239, on four types of coal samples sourced from the Huainan mining area. The results demonstrated that filter aid 1239 exhibited remarkable effectiveness on both flotation cleaned coal and coarse fine slime, with a discernible impact on coal slime as well. By modulating the hydrophobicity of particle surfaces, hydrophobic filter aids effectively facilitated the dehydration of coal preparation products. These findings bear substantial significance for improving the dewatering and transportation processes of coal preparation products.
