Aggregate (also known as aggregate) is an essential raw material for producing concrete, accounting for about 70% of the concrete volume, and has a critical effect on the concrete performance. The aggregate can be classified into natural aggregate and machine-made aggregate according to the source, and coarse aggregate and fine aggregate (4.75-0.15 mm) according to the particle size. Fine aggregate is also known as sand. With the trend of tight natural aggregate resource constraint and increasingly enhanced environmental protection, the machined aggregate has replaced the natural aggregate to become the most important aggregate source in the construction market.

The existing machine-made aggregate shaping is commonly performed by a reaction crusher and an impact crusher, and a certain shaping effect can be achieved to a certain extent. Impact crushers and impact crushers utilize high-strength metal or nonmetal members to impact aggregates, so that the aggregates form severe collision on the impact members and the walls of equipment, and tips or edges are formed to preferentially fracture in the collision process between the aggregates and the members or the aggregates, thereby realizing the improvement of the particle shapes of the aggregates particles.
The shaping device achieves the shaping effect by means of severe random collision, and the strength of the shaping device is not uniform due to the differences of mineral types, content and mineralization properties of aggregate particles. Not only the corners are cracked in a severe collision, but also the whole ore may be cracked, so that large particles are cracked into a plurality of small particles, and cracks are formed even inside the particles. The ore is crushed and a large amount of stone powder with low economic value is produced. Therefore, if the proper shaping effect is achieved and the excessive crushing phenomenon is reduced, the shaping mode of the severe impact collision type has a great defect.
