The air inlet pipe 26 is connected to an external air pump. The nozzles 28 are arranged on the hollow plate 27. Under the action of the external air pump, high-pressure gas enters the interior of the hollow plate 27 through the air inlet pipe 26, and the nozzles 28 blow out the gas to purge the interior of the mixing box 2, thereby reducing the adhesion of cement raw materials inside the mixing box 2.

[0039] In this embodiment, five premixing boxes 5 are provided for easy measurement.

[0040] The working principle of a cement raw material homogenization device in the embodiment of the present application is as follows:

[0041] According to the total amount of cement raw material to be prepared, various cement raw materials are divided into several portions respectively, and then single portions of different types of cement raw materials are put into the interior of the premixing box 5. Under the action of the first motor 4, the first stirring component 6 works to stir the cement raw material inside the premixing box 5 once to achieve premixing of the raw material. After the premixing is completed, the first discharge valve 11 is opened, and the material enters the interior of the mixing box 2 through the first conveying pipe 10. Under the action of the second motor 8, the second stirring component 9 works to stir the cement raw material inside the mixing box 2 for a second time to improve the homogenization effect of the cement raw material.
