① The pre-homogenization yard can homogenize the composition of raw materials to reduce quality fluctuations to facilitate the production of higher quality clinker and stabilize the firing system for production.

② It can expand the utilization of mine resources and improve mining efficiency. Maximize the use of mine coverings and interlayers. No or less waste rocks are produced during mining.

③ It is possible to relax the quality control requirements of mine mining and reduce the mining cost of the mine.

④ Strong adaptability to sticky and wet materials.

⑤ To provide the factory with long-term stable raw materials, it is also possible to batch raw materials of different components in the yard to make it a yard to be batched to create conditions for stable production and improved equipment operation rate.

⑥ High degree of automation.
