[0001] The invention relates to the technical field of cement production, and in particular to a green low-carbon cement production line utilizing sea mud and industrial solid waste. Background Art

[0002] Cement: Powdered hydraulic inorganic cementitious material. After adding water and stirring, it becomes a slurry, which can harden in the air or in water, and can firmly cement sand, stone and other materials together. When producing low-carbon cement, the raw materials need to be ground and mixed. Depending on the different raw materials used, the specific process needs to be adjusted differently. Regardless of the raw materials, the raw materials need to be mixed with an alkaline activator.

[0003] In the prior art, during the production of low-carbon cement, when the raw materials are stirred, the bottom surface is mostly set horizontally and the two sides are set in an arc shape. In this way, when the stirred cement is discharged, it is easy for it to remain inside the mixer. If it is not taken out in time, the cement is easy to mix with moisture in the air, and some of it will solidify inside the mixer. After long-term use, it is easy to rub against the mixing frame, causing damage to the mixing frame and the inner wall of the mixer, thereby reducing the service life. Summary of the invention
