Description

Technical Field

[0001] The utility model relates to the technical field of sandstone crushing and processing, and more specifically, to an automatic aggregate shaping device. Background Art

[0002] Sand and gravel aggregate is a general term for sand, crushed stone, rubble stone and other materials in water conservancy projects. Sand and gravel aggregate is the main building material for structures such as concrete and stacked stones in water conservancy projects. Sand and gravel aggregates from natural riverbeds are made into finished aggregates after screening and washing. In order to adjust the grading of coarse aggregate and crush oversized stones, crushing equipment is also required as a supplementary means.

[0003] In engineering construction, the particle morphology, shape, gradation, and needle-like particle content of aggregates have a very important influence on the working performance, mechanical properties, and durability of the prepared concrete. Compared with the aggregates before shaping, the sand and gravel aggregates after shaping are closer to spherical shapes with rough surfaces. Their particle morphology and shape are improved, and the particle gradation is optimized. At the same time, the content of needle-like particles is reduced, which can significantly improve the performance of concrete. The existing technology generally crushes and shapes aggregate particles by hammer crushing, jaw crushing, and impact crushing. However, due to the large difference in the size of stone particles before crushing, the particle size of sand and gravel aggregates after simple crushing still has certain differences, and some particles are larger and have more edges and corners, resulting in a large change in the output aggregate volume, which requires secondary filtration and sorting, affecting its use. Utility Model Content
