VSI series vertical shaft sand making machine is a newly designed product based on China's working conditions. It is a high-performance sand making equipment with a considerable level of domestic production at present. The sand making machine is designed to provide high-quality sand and gravel aggregate for expressways, high-speed railways, high-rise buildings, municipal administration, hydropower dam construction and concrete mixing plants. It is an equipment in the field of artificial sand making and stone shaping. It is a new sand making machine with considerable level newly developed by our company. Excellent cost performance. Long term technical accumulation and modern processing equipment ensure the position of VSI series new sand making machine in the domestic sand making industry.

1. Low cost and little wear

2. Powerful function and good sand making effect VSI high-efficiency sand making machine has fine crushing and coarse grinding functions; High crushing rate, environmental protection and energy saving.

3. Wide range of materialsVSI high efficiency sand making machine is suitable for crushing medium hard and extra hard materials; It is less affected by the moisture content of the material, and can crush stones with a moisture content of about 8%.

4. Energy saving and environmental protection, less dust pollutionThe working noise of VSI high-efficiency sand making machine is lower than 75 dB, with less dust pollution; The product is cubic, with high bulk density and very little iron pollution.

Full center feeding: the materials fall into the feeding hopper of the sand making machine, enter the high-speed rotating swing wheel through the central feeding hole, and are rapidly accelerated in the swing wheel. The acceleration can reach multiple times the gravitational acceleration, and then shoot out from the swing wheel at high speed. First, they collide with another part of the materials that fall freely after rebound, and then they collide with the material lining (stone striking stone) or counterattack block (stone striking iron), and are bounced up to the top of the vortex chamber, It also changes its movement direction, deflects downward, and collides with the materials emitted from the impeller channel to form a continuous material curtain. In this way, a piece of material is subjected to two or more times of probability impact, friction and grinding crushing in the vortex crushing chamber. The crushed materials are discharged from the lower discharge port.
