Experiment study on flocculation settlement of high muddied coal slurry in Pansan coal preparation plant

In order to improve the settling effect of small coal slurry in Pansan coal preparation plant,taking the initial settlement speed of the coal slurry water as the investigation indexes,studied the effect of concentration of APAM solution,hardness,concentration and temperature of coal slurry on the settling effect,and determined the best settling condition of coal slurry in the plant.The test results showed that for the coal slurry with the quantity density is 80 g/L,while the APAM dosage with the concentration is 2 g/L,the hardness of coal slurry is 40 mg Ca O/L and the temperature is 20 ℃,the settling result is best.
