碩士 === 國立高雄應用科技大學 === 電機工程系博碩士班 === 106 === The impact crusher research on the crushing of rocks uses the methods of simulation and finite element analyze to obtain the corresponding forces and stresses between the theoretical mechanism and the ore being tossed at different speeds. At each fixed rotation speed, a set amount of real sample data was then randomly selected, and the results of the experimental statistics were used to confirm the average material yield of the ore particle size under those conditions. These results were then used to interpret the circumstances of the data so that further results could be predicted under the same conditions. Finally, the coefficient of variation results were calculated by sampling at actual set speeds when the crusher was working at a sufficiently high rotational speed; this way, the average yield of the ore particle size at a given set speed was actually obtained to determine the real material yield.
