Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a raw material crushing device for concrete production. Background Art

[0002] The term concrete refers to cement concrete obtained by mixing cement as a gelling material, sand and stone as aggregates, and water in a certain proportion. It is widely used in civil engineering. The concrete raw materials need to be crushed before use to make the crushing balls of the concrete raw materials consistent in size and improve the strength of the concrete. The existing raw material crushing device for concrete production (Announcement No.: CN213320930U) has the following disadvantages in use:

[0003] During use, the water in the water tank is transported to the spray head through a water pipe. When the concrete is crushed, the spray will reduce the dust. However, since the surface of the concrete is moist, it is easy for the concrete to stick together when it is screened on the screening plate, which in turn causes the screening plate to be blocked, affecting the screening effect of the screening plate. For this reason, this patent proposes a raw material crushing device for concrete production to solve the above problem. Utility Model Content
