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 a four-debalance-type vibration exciter, which excites oscillations of force factors according to an asymmetric law, the change in the direction of the largest force factor in absolute value by the opposite is achieved by changing the initial position of slow-moving unbalances.
EFFECT: technical result is a variation in the speed of transportation and higher efficiency of separation of grain mixtures.
