Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete production, in particular to a crushed stone bin. Background Art
[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates, mixed with water in a certain proportion and obtained by mixing. It is also called ordinary concrete and is widely used in the field of civil engineering.
[0003] When concrete is produced, a crushed stone bin is needed to crush the stone. However, some existing crushed stone bins directly export the crushed stone without screening it. The unscreened crushed stone may contain unnecessary fine particles or oversized particles, which will lead to unstable quality of concrete materials. At the same time, crushed stone with uneven particle size will also affect the performance and strength of concrete.
[0004] In summary, the present application now proposes a gravel bin to solve the above-mentioned problems. Utility Model Content
