Abstract

The invention provides a material pulverization particle size control system and a control method and application thereof, so as to solve the problem that the pulverization process of the positive electrode material of a lithium battery easily leads to uneven particle size. A material pulverization particle size control system includes: an operation interface unit for inputting setting parameters of the particle size of the pulverized material; a detection unit for performing periodic sampling to obtain particle size measurement values ​​and recording actual parameters of the number of particle size data and sampling times; The unit is used to calculate and judge the actual parameters and the set parameters, and control the work of the execution unit and the detection unit according to the judgment result; the execution unit is used to implement the particle size adjustment mechanism in the material pulverization and pulverization process. Through real-time monitoring of the particle size in the crushing work, the automatic control and adjustment mechanism is found to be abnormal in particle size, and the dynamic sampling cycle is matched with the multi-stage particle size adjustment, so that the specific situation of abnormal particle size can be judged at the fastest speed, and the abnormal adjustment can be completed in a short time; Improved efficiency and guaranteed granularity consistency.
