[0002] In the construction industry, the storage and transportation of fine aggregate dry powder (such as cement, gypsum powder, lime powder, etc. cementitious materials) is a key link in the construction process. The traditional fine aggregate storage method often uses open or simple closed storage yard. This method has many shortcomings. First, open storage is easily affected by weather, such as rain, wind and sand, which will cause fine aggregate to be damp, caked or contaminated, which will seriously affect its performance. Secondly, the simple closed storage facility often has poor sealing performance, which cannot effectively prevent the fine aggregate from being dusted during storage, which will pollute the environment and may also pose a threat to the health of workers.

[0003] In order to solve the above problems, the industry began to use special fine aggregate dry powder storage bin for storage. However, the existing fine aggregate dry powder storage bin still has some limitations in design and use. For example, the discharge port of some storage bins is not reasonably designed, which causes the fine aggregate to be easily blocked, unevenly discharged or difficult to control the discharge speed during discharge. These problems not only affect the construction efficiency, but also cause the waste of fine aggregate and the increase of cost.

[0004] Therefore, the utility model designs a fine aggregate dry powder storage bin for producing building products, which has reasonable structure and is easy to use. The storage bin should be able to effectively solve the above problems of fine aggregate during storage and transportation. Specifically, a fine aggregate dry powder storage bin is needed, which can ensure that the fine aggregate is not affected by the external environment during storage, the discharge is uniform and the speed is controllable, and can simplify the transportation process, reduce the cost of equipment and maintenance cost.
