Background

The concrete is artificial stone which is prepared by taking cement as a main cementing material, adding water, sand, stones and chemical additives and mineral admixtures if necessary, mixing the materials according to a proper proportion, uniformly stirring, densely molding, curing and hardening. Concrete is mainly divided into two stages and states: plastic state before setting and hardening, namely fresh concrete or concrete mixture; hardened, i.e. hardened concrete or concrete. The concrete strength grade is divided into a cubic compressive strength standard value, and the Chinese common concrete strength grade is divided into 14 grades: c15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80. In concrete, sand and stone act as a framework, called aggregate; the cement and water form cement paste, and the cement paste wraps the surface of the aggregate and fills gaps of the aggregate.

During traditional sand material screening, can lead to the phenomenon that sand appears agglomerating because of reasons such as weather rainy when sand material transports, need sun-dry back manual work to handle, the chinese patent is disclosed: the utility model provides a gravel sieving mechanism for concrete production, patent application no: 202020087134.2, this patent is through "through setting up agitating unit, treat the gravel of screening and stir, smash the gravel of conglomeration, thereby the normal clear of screening has been guaranteed, and through setting up the hot-blast main in the inside of agitator tank, the external dry hot air heat source of hot-blast main carries out effectual drying to the gravel, avoid plugging up the emergence of the screen cloth condition because of the gravel surface is moist, guarantee the normal screening of gravel, but this equipment cost is expensive and operating procedure is loaded down with trivial details, consequently, need for a sand material sieving mechanism for concrete production now urgently.
