The aggregate is used as a framework material of concrete, is a key raw material for constructing a concrete framework and is a large quantity of building material products consuming a lot of natural resources, and accounts for about 70 percent of the composition of the concrete. With the social development and the continuous expansion of urban construction, particularly the continuous expansion of the construction of highway, high-speed rail, airport infrastructure, industrial and civil buildings and the like, the requirement of the aggregate for the construction is more and more increased, and simultaneously, more and higher requirements on the grain type and the grading of the aggregate are provided. With the trend of resource constraint of natural sandstone aggregate and the increasing enhancement of environmental protection, the recycled environment-friendly aggregate gradually becomes a main source of sandstone for construction in China. The recycled environment-friendly aggregate is the aggregate produced by using industrial waste. The recycled environment-friendly aggregate is produced by adopting a mechanical crushing principle, and the currently outstanding problems are that the recycled environment-friendly aggregate which is produced by mechanical processing is unreasonable in gradation, high in porosity and more in edge angle, contains a certain amount of flaky aggregate and needle-shaped aggregate, cannot meet the production requirement of concrete, influences the workability of concrete mixtures, brings adverse effects on the mechanical property and the durability of the concrete, and directly influences the quality of building engineering.
At present, aggregate shaping generally adopts a vertical shaft impact type gravel shaping machine, and adopts central feeding along with annular falling feeding: the material falls into the feed hopper, falls through the annular hole again, is divided into two by the bulk material awl. One strand enters the impeller rotating at high speed through the material distribution disc, and the other strand falls down from the periphery of the material distribution disc. The material entering the impeller is quickly accelerated in the impeller and then ejected, firstly impacts and crushes with the other part of the material of the free falling body around the bulk cone, then impacts on the vortex liner in the vortex cavity, firstly rebounds to the top of the crushing cavity, then deflects to move downwards, and the material ejected from the impeller flow channel impacts to form a continuous material curtain and is finally discharged through a lower discharge outlet. The equipment can damage the recycled aggregate due to forced broken stone shaping by using mechanical motion, forced abrasion of the equipment is increased, and the equipment has more parts, is easy to cause failure shutdown in the using process, increases the use cost and reduces the production efficiency. Therefore, the shaping system for the waste resource recycled environment-friendly aggregate has the advantages of simple structure, low energy consumption and less environmental pollution.
