Magafloc 5250 used for coal  processing can be replaced by Asiafloc 72520

Coal washing field with polyacrylamide is to promote mining, coal washing recovery of solid sediment in water, water clarification, at the same time can be recycled useful solid particles, and avoid environmental pollution. With the improvement of coal mining mechanization, the proportion of fine coal content is increasing, part of which causes a vicious cycle in the washing process. In order to realize clean coal washing, it is necessary to accelerate the settlement of fine coal in coal slime water to ensure a low concentration of circulating water.

The selection of anionic polyacrylamide is also very complex, anionic PAM hydrolysis degree 5 to 30, molecular weight 6 million to 18 million, very many models, the composition of coal, different content of coal with precipitation agent is not the same. From the start of the workshop of the extraction wastewater samples to practice the test in room, the big test workshop, detailed questions, detailed analysis, selection should be based on the experiment to be sure, each kind of coal washing wastewater has its unique characteristics, we determine the approximate dosage in the experiment, we examined the flocculating results in the experiment, in the experiment we capital accounting department, The precipitant most suitable for your coal washing water is the most economical, the most effective.

Anionic 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 coal preparation plant, it is mainly used for:

1. Polyacrylamide flocculant is added to the slime water deep purification concentrator to accelerate the settlement of slime and reduce the concentration of overflow water. Particle settlement, water overflow, cycle coal washing.

2, in the vacuum filter or filter press, add polyacrylamide flocculant, improve the filter cake structure, reduce the filter cake moisture, improve the filtration speed.

3, there are some special high sulfur coal, engineering coal, PH acid coal washing water to use non-ionic PAM, this should also be determined by laboratory test analysis!
