In the actual operation process, when partial blockage occurs in the coarse crushing stage, crushing efficiency fluctuates or abnormal conditions such as outflow of larger medicinal material particles along with discharge exist, the feeding amount and the material state in the fine crushing stage change, but the fine crushing parameters still maintain original setting generally and are difficult to match and adjust in time, so that the problems of low fine crushing treatment speed, unstable operation state, overlarge crushing load, high energy consumption, aggravated equipment wear and the like are caused.
