[0046] To sum up, the use process and working principle of the application are as follows: in use, the main material is poured from the main feeding pipe 2 into the inside of the main pipeline 1 from the lower end of the main feeding pipe 2, and the auxiliary material is added from the upper end of the auxiliary feeding pipe 11, and the auxiliary material flows into the inside of the auxiliary material pipe 3 from the lower end of the auxiliary feeding pipe 11, the variable frequency motor 44 is started by the PLC controller 6, the auxiliary material shaft 41 is driven to rotate by the variable frequency motor 44, the auxiliary stirring blade 42 conveys the auxiliary material to the inside of the flow guide pipe 43, the auxiliary material in the flow guide pipe 43 falls into the main pipeline 1 from the lower end of the flow guide pipe 43, so that the auxiliary material and the raw material are mixed together, the main motor 10 is started by the PLC controller 6, and at this time the main shaft 8 and the main stirring blade 9 are driven to rotate by the main motor 10, so that the auxiliary material and the raw material are mixed.

[0049] Similarly, a set of flow limiting structures 5 can be arranged in the auxiliary feeding pipe 11, so that the flow of the auxiliary material from the auxiliary feeding pipe 11 into the auxiliary material pipe 3 can be more conveniently controlled, and the amount of auxiliary material entering the main pipeline 1 can be more accurately controlled by the cooperation of the adjusting device 4.
