Description

Technical Field

[0001] This utility model relates to the field of soil stabilization material production technology, specifically to a raw material uniform mixing device for soil stabilization material production. Background Technology

[0002] Soil stabilizers are materials used to alter the physical and chemical properties of soil, making it more solid, durable, and stable. The main principle behind their operation is to change the soil's structure and properties through chemical or physical reactions with soil particles. For example, materials like cement and lime can react with moisture in the soil to generate new compounds, thereby filling the pores between soil particles and increasing the soil's density and strength.

[0003] When existing mixing devices mix multiple materials, the differences in particle size between the different materials can affect the uniformity of the mixing. Furthermore, the solidified material in its granular state is not easy to react and mix with soil particles.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a uniform mixing device for raw materials in the production of soil stabilization materials, in order to achieve a more practical purpose. Utility Model Content
