Abstract

The design features of vibratory transporting devices with elastic actuators, mainly feeders, developed at the Chinakal Institute of Mining SB RAS are described. In order to increase the distance of transportation and the possibility of using such machines in various technologies for processing minerals, it is proposed to use an additional vibration source in their drive. The dynamics of an elastic actuator was investigated during the operation of two vibration exciters in a synchronous mode and a beat mode by physical modeling. The conditions of stability are found and the scope of application of both modes is determined.
