Background

Along with the progress of modern construction of our country, the concrete industry develops rapidly, the demand and the quality of the building industry to the concrete are improved continuously, and the demand of aggregate as the raw material of the concrete is increased continuously. In the process of producing concrete, the aggregate is wrapped by cement paste consisting of water and cement, and mainly plays a role of a skeleton in the concrete, and the gradation of the aggregate has direct influence on the properties of the hardened concrete. Aggregate gradation means the proportion distribution of each grade of the gravel for concrete, and can be divided into continuous gradation which is gradation composed of aggregates of continuous grade, each grade exists continuously to form a stable stacking structure, and discontinuous gradation is one or more kinds of grain gradation removed on the basis of continuous gradation. Aggregate gradation is one of important indexes of aggregate. Different aggregate grades have very important influences on the strength, durability, impermeability and the like of concrete. The aggregate with good gradation has smaller total surface area and stacking void ratio, can reduce the dosage of slurry and save the production cost of concrete.

The early aggregate sources mainly comprise natural sand and weathered pebbles. However, the natural sandstone can be formed only by the accumulated effect of the natural environment, has the characteristics of long forming period and small accumulation amount, and belongs to non-renewable resources. In addition, the natural sandstone can cause the phenomena of river bed water level reduction, ecological environment damage and the like in the process of large-scale mining, and the machine-made aggregate formed by crushing rocks by an impact crusher is gradually used as the main raw material of the concrete aggregate. The machine-made aggregate is suitable for the requirements of greenization, scale and intensification of building materials, has the characteristics of ecology, environmental protection and the like, and has more and more attention in recent years. However, in the production process of the machine-made aggregate, excessive needle-shaped and sheet-shaped aggregates are added into concrete, so that the workability of fresh concrete is poor, and the construction quality and the mechanical property and durability of the concrete are affected, so that an intelligent grading process and device for the concrete aggregate are required to be provided.
