FIELD: engineering.
SUBSTANCE: invention relates to vibration engineering and can be used in the process and transport equipment in the fields of industry associated with processing of bulk materials. The method is to excite mechanical oscillations by the centrifugal vibration exciter comprising four eccentric weights, having equal unbalanced mass in pairs, eccentricities and angular velocities, with appropriate phasing of the first and second pairs of eccentric weights, the ratio of their angular velocities, as well as the ratio of the maximum power factors generated by the inertial forces of slowly-rotating and inertial forces of rapidly rotating eccentric weights.
EFFECT: possibility of varying the speed of transportation and increase in technological efficiency of the processes of separation of grain mixes.
