Experiment Study on Capture Performance of New Coal Capturer PCF

In order to improve the floatation effect of the slime and to reduce the consumption of the slime floatation agent, a lab comparison experiment method of the floatation agent was applied to the experiment on the capture performances, consumption and floatation speed of the new coal capturer PCF.The results showed th at in comparison with the kerosene and diesel oil, with the application of the PCF as the consumption of the floatation agent could be reduced by 45.45%60.45% at the similar ash content of cleaned coal.The clean coal production rate could be improved by 1.65%4 .34%, the ash content of the tailings would be increased by 1.50%1 .6 6% and the recovery rate of the combustible mass could be increased by 1.95%4. 95%. Under the condition of the same agent consumption, the clean coal production co uld be improved by 13.25%23.61%, the recovery rate of the combustible mass could be improved and the floatation speed could be improved.Therefore, the PCF could be a high efficient capture for application.
