Performance Comparison of Different Impellers in Ф6.5m Pulp Conditioner

Abstract:

The success of 200m³ and 300m³ flotation cell in industrial application calls for matching conditioner. Experimental research in Ф6.5m conditioner is taken to select suitable impeller and rotating speed. 4PB impeller and 4HB impeller are compared in flow features and power consumption in single phase flow. The conclusion that the power consumption per cycle-volume by 4HB impeller is 80% of that by 4PB impeller is drawn. 4PB impeller and 4HB impeller are compared in suspension characteristics in double-phase flow. The conclusion that 4HB impeller can suspense the mineral by lower power consumption while 4PB impeller cannot under the same situation is drawn. Thus 4HB impeller is prior to be used in large pulp conditioner. Based on this experiment, many large pulp conditioners are successfully applied
