K6CM Target Application Dryers (for spray-drying powders) Powder Facility details Air is sprayed while the air injection pipe is rotated by a motor to prevent powder from accumulating on the inner wall of the conical drum. Rollers are installed along the inner wall of the conical drum. Roller Powder accumulation Motor operation conditions Air spray Conical drum 1.5kW/200V/4 poles Direct connection to commercial power supply:
50Hz Air injection pipe Roller Failure mode Load abnormality Belt Detection parameters Degradation level 1 Measured motors Degradation level 1 measurement results obtained from K6CM-CI Current waveform data Stirring system Current (A) Measurement data ideal sine wave Current (A) Measurement data ideal sine wave Normal Condition Abnormal Condition Value for a normal working motor: 21 Value for motor not working normally:
32 Roller is not rotating due to powder lodged in its mechanism Roller is rotating normally Alarm threshold degradation level 1 for this application (examples) Expected implementation effects When the guide roller's diameter decreases due to wear, the contact area between the roller and the dryer wall decreases as well, causing the air injection pipe to oscillate significantly. This increases the load on the pipe and the dryer axis, which in turn can lead to damage. K6CM series products can prevent such problems from happening. 19 IV.
