Abstract: With popularization and application of aerobic composting，theoretical research on performance parameters including power consumption is of great significance to promote further development of turning machinery.By systematically describing working principle of drum tuner，factors affecting power consumption of drum turner were analyzed，and relationship between power consumption of drum turner and its affecting factors was established.Based on method of experiment modeling，experimental idea of establishing power consumption model of drum turner was proposed，which provided a theoretical reference for research on power consumption of drum turner.
