s3: the grinding wheel (16) is driven by the motor (7) and the rotating shaft (28) to rotate, so that the grinding teeth (17) and the grinding supporting plate (18) continuously impact and extrude the coarse ore with smaller volume, further the coarse ore with smaller volume is changed into the small coarse ore particles, and then the small coarse ore particles can fall into the bearing disc (20) through the leakage holes (34), at the moment, a worker can select to continuously grind the small coarse ore particles or directly output the small coarse ore particles, if the small coarse ore particles are directly output, the first electromagnetic valve (23) is closed through the controller (6), the second electromagnetic valve (24) is opened, and at the moment, the small coarse ore particles can be directly output through the primary discharging pipe (12);
s4: if the staff selects to continue to carry out crocus processing to the small granule of coarse ore, then open first solenoid valve (23) through controller (6), and close second solenoid valve (24), the small granule of coarse ore just can get into between carousel (25) and abrasive disc (27) through passage (22) this moment, carousel (25) rotate under the drive of motor (7) and pivot (28), thereby make carousel (25) drive grinding rod (26) motion, make and grind pearl (31) roll on abrasive disc (27), and then grind the small granule of coarse ore, make the small granule of coarse ore become the ore powder, the ore powder passes through second grade discharging pipe (13) output at last.
