The invention discloses a feedback-type energy-saving stone breaking and impacting device and an ore breaking method, and belongs to the field of pulverizing equipment. The feedback-type energy-savingstone breaking and impacting device is characterized in that the feedback-type energy-saving stone breaking and impacting device comprises a conveyor (3) and a stone breaking and clamping and impacting device (1) located on one side of the conveyor (3); a pushing mechanism which drives the stone breaking and clamping and impacting device (1) to move integrally is arranged on one side of the stonebreaking and clamping and impacting device (1); a plurality of vibration puncher pins (102) which are arranged radially are uniformly arranged on the stone breaking and clamping and impacting device(1); and an electromagnetic driving device, a sensor (104) and a photographic device which are independently controlled are arranged on each vibration puncher pin (102). A stone breaking mode and a stone breaking structure of a traditional stone breaking machine are changed, and own crack situations of stone blocks are detected in real time and are fed back to the subsequent stone breaking and clamping and impacting device, so that vibration impacting can be carried out on the stone blocks specifically; sound and vibration, which are fed back to the puncher pins, of the stone blocks are collected constantly in the impacting process, and the stone blocks to be impacted are subjected to the vibration impacting specifically, so that energy consumption can be lowered, and the stone breaking efficiency is improved.
