All walks of life in the use of polyacrylamide models are different. So what type of polyacrylamide should be used in the mining industry? In the field of coal washing, polyacrylamide is used to promote the settlement of solids in the water recovered from mining and coal washing, clarify the water, recover useful solid particles and avoid environmental pollution. With the improvement of mechanization degree of coal mining, the proportion of fine coal content is more and more large, some of which cause a vicious circle in the washing process. In order to realize clean water coal washing, it is necessary to accelerate the settlement of fine coal in slime water to ensure low circulating water concentration. According to the characteristics of water quality in mining industry, Lvyuan Environment Group Co.,Limited suggested to use anionic polyacrylamide.
Polyacrylamide is a kind of high efficient organic polymer flocculant, which is often combined with inorganic coagulant to treat slime water in coal preparation plant. In the coal preparation plant, the main functions of polyacrylamide are as follows: (1) adding polyacrylamide flocculant to the deep purification thickener of slime water can accelerate the settlement of slime water and reduce the concentration of overflow water. (2) Adding polyacrylamide flocculant to vacuum filter or filter press can improve the structure of filter cake, reduce the moisture content of filter cake and increase the filtration speed.
