The invention discloses a processing system and a construction method capable of improving the fineness modulus of natural sand. The advantage of high fine aggregate content of a natural river bed is fully utilized, and a vertical-axis impact crusher is selected to process small stones into artificial sand with high fineness modulus, so that the shortcomings of low natural sand content and low fineness modulus are compensated and overcome, the yield and production quality of the sand are improved, and the running cost of the whole system is also lowered. The system and the method are particularly applied to the working conditions of low fineness modulus, low natural sand content and high fine aggregate content of natural grits mined underwater.
