Coal Preparation Plant
Introduction:
Polyacrylamide PAM for coal washing is a more professional polyacrylamide. In fact, only the chemical composition of the interior has been adjusted. The effect of special polyacrylamide for coal washing is several times better than that of general polyacrylamide. The effect is very obvious in coal washing pressure filtration, or in the discharge of groundwater. Its reaction time is about 5 seconds, and the effect of precipitation can be seen. So the reason why many coal mines choose special flocculant for coal washing is that. Coal mined in coal mining usually contains part of impurities, and the separation efficiency of coal and impurities can be improved by adding flotation agent. When the clean coal is floated, the tailings settle. Then the clean coal in tailings can be recovered by sedimentation, filtration or centrifugation. Polyacrylamide PAM is used in the settling process to promote solid-liquid separation. Then it is sent to the concentrator, and the clean water is recovered and recycled by the overflow of the concentrator. Powdered coal is filtered and centrifugally recovered. Polyacrylamide was added again in the process of filtration and centrifugation to improve the separation efficiency. In order to meet the needs of users, we have produced special flocculant for coal washing, which has a better effect on different coal mines and greatly reduces the dosage of medication.
