[0002] Concrete is one of the most important civil engineering materials and is widely used in the construction industry. The main materials for producing concrete are cement, sand and gravel. In the concrete preparation project, cement, sand and gravel usually need to be mixed and then further processed. Therefore, mixing the concrete raw materials is an important step in concrete processing.

The system includes a fuselage, and is characterized in that it also includes: a feeding unit, which is arranged at the upper end of the fuselage, and is used to control the orderly feeding of materials; a mixing unit, which is arranged in the +X direction of the fuselage: a cement dispersing component, which is arranged inside the mixing unit. Sand freely falls to the bottom of the mixing barrel along the outlet hole at the lower end of the screening area. At the same time, when cement is transported from the left side of the cement transfer barrel to the inside of the grid barrel through the spiral rod, the cement is first dispersed out of the inside of the grid barrel along the injection hole, and then input into the dispersion mechanism by the air pump mechanism for diversion, and further blown away along the gas ejected from the jet hole.
