| description | The invention discloses a particle size regulation and control method of an airflow crushing device, relates to the technical field of regulation and control of airflow crushing devices, and adopts a feedforward compensation matrix method to perform decoupling control on the rotating speed of a grading wheel and the rotating speed of an induced draft fan which have a coupling relationship. Controlling output values of the rotating speed of the grading wheel and the rotating speed of the induced draft fan after decoupling control to obtain real-time granularity, feeding back the real-time granularity to the input end of the airflow crushing control system, comparing a preset granularity threshold value with the real-time granularity, and respectively adjusting the rotating speed of the grading wheel and the rotating speed of the induced draft fan according to a comparison result of the preset granularity threshold value and the real-time granularity, the interaction of the rotating speed of the grading wheel a |
