FIELD: agriculture; machine building.
SUBSTANCE: invention relates to vibration equipment, particularly to agroindustrial complex, and can be used for grain processing enterprises in the process and transport equipment. According to the disclosed method, in a four-balance-type vibration exciter, which excites oscillations of force factors as per asymmetric law to provide a symmetric law of oscillations, which means equality of maximum absolute values of the power factor in positive and negative directions, the initial position of fast rotating weight unbalances is changed.
EFFECT: variation of speed of transfer and higher efficiency of separation of grain mixtures.
