Technical Field

[0001] The utility model belongs to the technical field of concrete production, and in particular relates to screening equipment for concrete production. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates, also known as aggregates, water, and admixtures and additives added when necessary, which are prepared in a certain proportion, uniformly stirred, densely formed, and cured and hardened. Concrete has the characteristics of abundant raw materials, low price, and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make its scope of use very wide. It is not only used in various civil engineering projects, but also in shipbuilding, machinery industry, ocean development, geothermal engineering, etc. Concrete is also an important material. In daily concrete production, it is often necessary to screen the raw materials. In the past, the raw materials were screened manually with a sieve, which was too inefficient. Utility Model Content
