Description

Technical Field

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

[0002] Fine aggregates play an important role in concrete. They are granular materials in concrete and mainly serve as skeleton and filling materials. Fine aggregates are usually divided into fine aggregate and coarse aggregate. Fine aggregates, whose particle diameter is usually between 0.16 and 5 mm, mainly serve to fill the voids in concrete. Common fine aggregates include natural sand, such as river sand, sea sand and valley sand. Coarse aggregates, whose particle diameter is greater than 5 mm, mainly serve to increase the strength and rigidity of concrete. Commonly used coarse aggregates include crushed stone and pebbles.

[0003] When producing aggregates, the crushing devices in the prior art usually do not crush the aggregates thoroughly in a single time, so the aggregates need to be crushed and screened multiple times to gradually screen out bone powder with qualified particle sizes. However, the process of screening bone powder multiple times is relatively cumbersome, and a large amount of manpower and time are required to transport the bone powder. Therefore, a crushing device for fine aggregate processing is proposed to solve the above problems. Utility Model Content
