[0002] Cement is one of the most important materials in concrete mixing, which enables the mixture to harden into a strong structural material under the action of water. Cement hydration reaction is one of the most basic reactions in the mixing process. This reaction causes the chemical substances on the surface of cement particles to dissolve and form a colloid, namely hydrated colloid, which can wrap aggregates and sand to form hardened concrete.

However, in the process of feeding the materials, the materials collide with the bottom wall of the container, which is likely to generate large dust and overflow from the opening of the container, causing adverse effects on the environment and the health of workers. Secondly, common mixing devices mostly use a mixing shaft to drive the mixing paddle for mixing. The contact area between the mixing paddle and the material is limited, and the mixing efficiency is low. Utility Model Content
