Traditional equipment adopts steel construction building form, compact structure, and area is few, saves space, but has following defect: (1) the vibrating screen in the building station is generally arranged on the middle and high layers of the building station, the vibrating screen vibrates greatly when working, in order to ensure the safety of the building station, the steel structure strength of the building station needs to be increased, and the equipment investment is increased; (2) the requirements on the raw materials are strict, the processing capacity is weak, the stone powder proportion contained in the machine-made sand is difficult to control, the ultrafine powder is difficult to remove, the machine-made sand is unreasonable in gradation, and when the raw materials contain powder or mud, the dust removal cost is high; (3) the sand making process is usually only simple crushing, and although the particle size can be ensured, the shape of the particle is not regular enough, so that the quality of the finished sand is influenced; (4) the equipment configuration is single, the yield of the finished sand is low, and the energy waste is large. Therefore, the sandstone aggregate produced by the traditional sand making equipment and process cannot meet the requirement of high-performance concrete, and a new process and equipment must be developed to produce high-quality fine sandstone aggregate and ensure the stability of the product.
