Sand is one of the important raw materials for infrastructure construction. At present, it has become an inevitable trend of the mechanism sand to replace natural sand.In order to meet the market demand, Kefid developed VSI series and VSI6S series high-performance sand making machine for pebbles, granite, limestone and other raw materials to produce quality mechanism sand.They can be used for mixing stations, dry mortar, cement products, aggregate, large-scale construction projects supporting sand.

                                                                                                                                  

 

The impeller structure of Kefid VSI6S sand making machine adopts new four-port design to improve the material throughput. Compared with the three-port impeller, the crushing efficiency increased by 20% or more.

 

In addition, VSI6S new sand making machine adopts "stone hit stone" and "stone hit iron" mode, greatly reducing the wear-resistant use of types; and optimize the impeller part of the structure and manufacturing process, the service life of the impeller part is increased by 30-200%, which greatly reduces the post-maintenance cost.

 

At present, Kefid VSI6S sand making machine has been successfully applied to many sand production sites in the world and widely praised by the customers.
