V6S series vertical shaft impact crusher (sand making machine) is based on the original high-performance VSI series and combined with actual running condition under different working conditions as well as operator's feedback. By improving the feeding mode, optimizing the broken cavity, adopting new rotor designs and installing lifting device etc, it reduces flow resistance of stones, increases throughput capacity,reduces wear rate of spare parts,increases utilization ratio,extends maintenance cycle and decreases repair time. Which has the characteristics of energy saving, long service life and wide application, help the sand plants develop to large-scale plants with centralized, environmental protected and capacity requested.
