Research Status and Development Trend of Mechanized Sand Production Process and Equipment Optimization

With the continuous development of engineering construction industry, the demand for sand used in construction is increasing, the traditional natural sand is increasingly in short supply, and the demand for mechanical sand is increasing. The vertical shaft impact sand machine is an important equipment machine in the production process of mechanical sand. The rotor in the vertical shaft impact sand machine is the core part of the normal work of the sand machine. Studying the rotor in the vertical shaft impact sand machine can improve the efficiency and stability of the sand machine in the sand making process. Compared with the research results at home and abroad, the type and research direction of rotor structure are summarized, and the development trend of vertical shaft impact sand making machine is proposed.
