Ensuring self-synchronization of unbalanced vibration exciters for transveyers of overburden spreaders

Deep-level mining in open pits involves increased volumes of overburden. It is difficult to operate heavy-duty dump trucks at bottom levels of deep open pit mines due to limited size of working areas and high angles of roads. In this case, it is expedient to use more maneuverable crawler dumps or articulated dump trucks of comparatively low capacity and to rehandle mined rocks to larger capacity dump truck at bin trestles with forced discharge constructed on accumulation horizons. This article discusses mined rock discharge from an accumulating bin of the rehandling point by a set of vibratory feeders representing the bottom of the bin. These vibratory feeders are to provide reliable operation under high static and dynamic loads.
