[0011] (1) The gear transmission mechanism is driven by a rotating driving member to rotate, so that the gear transmission mechanism drives two main crushing rollers to rotate in opposite directions. When the gangue is put into the crushing machine body from the feeding hopper, the main crushing roller cooperates with the auxiliary crushing roller to crush the gangue, so as to crush the gangue into small particles and then sort and recover the pyrite therein. Compared with the traditional method of directly sorting and recovering the gangue, the recovery efficiency of the pyrite in the gangue is improved when the recovery device is used;
