The invention also discloses a self-adaptive online control method of the grading crusher, wherein a belt scale 2 carries out real-time monitoring and weighing on the current material quantity, and transmits a data signal to a programmable controller 3, the programmable controller 3 judges the material quantity to enter the grading crusher through the signal input by the belt scale 2, and outputs a suitable signal according to a self-adaptive control strategy to control the output frequency of a first frequency converter 4 and a second frequency converter 5, the first frequency converter 4 drives a first variable frequency motor 6, the second frequency converter 5 drives a second variable frequency motor 7, the first variable frequency motor 6 drives a first crushing tooth roller, the second variable frequency motor 7 drives a second crushing tooth roller, and finally the operation of the grading crusher is controlled in a suitable range.

In the process, the first variable frequency motor 6 and the second variable frequency motor 7 both run at the same frequency at the same time, so that the normal operation of the grading crusher is ensured.
The formula for the linear positive correlation is: when the feed amount was X t/h, the operating frequency K =10+40 (X-50)/(U-50). Taking the design processing capacity of 200t/h as an example, the running frequency K =10+40 (X-50)/(200-50), for example, the feeding amount is 100 t/h, the running frequency of the motor is 23.3HZ, namely, the rotating speed of the grading crusher and the feeding amount of the belt are in linear positive correlation in the design range.
