FIELD: physics.
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 invention, in four-debalance-type vibration exciter, which excites oscillation of power factors by asymmetric law, change of direction of maximum power factor by absolute value to opposite one is achieved by changing initial position of slow-rotating unbalances.
EFFECT: technical result is a variation in the speed of transportation and higher efficiency of separation of grain mixtures.
