Concrete is one of the most important civil engineering materials of the present generation. The artificial stone is prepared by a cementing material, granular aggregate (also called aggregate), water, an additive and an admixture which are added if necessary according to a certain proportion, and is formed by uniformly stirring, compacting, forming, curing and hardening. The concrete has the characteristics of rich raw materials, low price and simple production process, so that the consumption of the concrete is increased more and more. Meanwhile, the concrete also has the characteristics of high compressive strength, good durability, wide strength grade range and the like.

However, sand is one of the most main components in concrete, and the quality of the sand is directly related to the quality of the concrete, so that the sand needs to be pre-screened before the concrete is manufactured, and the influence of sand and stones on the quality of the concrete and further on the safety of buildings is avoided.

At present, sand materials are screened, and common screening methods include a manual method and a mechanical method, wherein the manual method is that workers raise sand materials to be screened and separate stones and other magazines in the sand by means of the screening effect of a sand screening net, and the mechanical method is that the sand screening barrel is obliquely arranged to screen the sand materials. In the process of mechanical screening, materials such as sand and stones are easy to block the screen, and the screening efficiency is reduced.

An effective solution to the problems in the related art has not been proposed yet.
