Coal washing special polyacrylamide is a more professional polyacrylamide. It has better precipitation effect than ordinary polyacrylamide. The coal mined during coal mining usually contains some impurities, and the separation efficiency of coal and impurities can be improved by adding flotation agents. The clean coal is floated out and the tail coal settles. The clean coal in the tailings is then recovered through sedimentation, filtration or centrifugation. Polyacrylamide is used in the settling process to promote solid-liquid separation. Then it is sent to the concentrator, and the clean water is recovered from the overflow of the concentrator and recycled. Powdered clean coal is filtered and centrifuged for recovery. Polyacrylamide was added again during filtration and centrifugation to improve separation efficiency. > Polyacrylamide used for coal washing is anionic, with a molecular weight ranging from 10,000 to 10,000. Special polyacrylamide for coal washing In order to quickly precipitate the slime water in the concentration tank, ensure qualified washing water and press filter slime production, and make the production run efficiently and economically, appropriate flocculants must be selected to strengthen the treatment of coal slime water. Special polyacrylamide for coal washing is a series of polymer flocculation and dehydration agents developed for the dehydration of coal slime in coal washing plants. This series of flocculants has high dehydration rate and is easy to use. It can be used for centrifugal separation of coal washing tailings. It can be used in the precipitation and filtration of pulverized coal and coal slime. It can increase the recovery rate of coal powder and increase the filtration rate. Different types of flocculants can be selected according to the different impurity components such as sulfur in the coal slime. Suzhou Haonuo Company is willing to cooperate wholeheartedly in selecting flocculation and dehydration agents with the best performance to meet the production process requirements and reduce production and operation costs for users as much as possible.
