Analysis and solution of vibration of coal mill

2021-2-16  (2) Through analysis, the baffle opening of the coal mill induced draft fan is 33%, which seriously deviates from the working point (fan operation curve) and runs at the lowest efficiency point. After calibration, the operating efficiency is about 78.4% and the shaft power is 160.71kW, indicating that the motor selection is too large and the no-load loss is also large.
