FIELD: process engineering.SUBSTANCE: invention relates to mining. Autosynchronous unbalance vibration exciters are mounted on smoothly damped veering body. Proposed method consists in starting the motors in turn. Note here that, first, one motor is started to start the second motors after the former runs at steady state above resonance mode of revolution. After stable above resonance mode of unbalance vibration exciters, said second motor is switched off with second motor running for vibratory support of rotation.EFFECT: decreased amplitude of resonance vibrations.2 cl, 1 dwg |
