A ball mill impact collision simulation test bench and method

The invention discloses a ball mill impact collision simulation test bed and a ball mill impact collision simulation method. The ball mill impact collision simulation test bed comprises a light gas gun, a steel ball, a high-speed camera, a dynamic strain gauge, a photoelectric speed measuring device and a data collection device, wherein the steel ball is launched by the light gas gun, the movement speed of the steel ball is measured through the photoelectric speed measuring device, the steel ball impacts a cylindrical rock test sample through a test box, the cylindrical rock test sample strikes a lining plate test sample under the impact load effect, the rock test sample and the lining plate test sample are horizontally arranged in an arc groove of a test box stander, the center of the arc groove is leveled to the center of the steel ball, the accuracy of the impact process is guaranteed, the impact collision process is precisely captured through the high-speed camera, an impact acceleration sensor, a strain plate and the like are arranged on the surface layer of a cushion test sample, an output signal is collected through the dynamic strain gauge and a data collection card, the signal is processed through a computer data processing system, so that the dynamic mechanics performance of a material in the ball mill impact collision process can be accurately achieved.
