Vertical Shaft Impact Crushers is also called Sand Maker, which is high-functioned equipment for making sand and shaping, is researched and produced by our corporation, absorbed with the advanced technology from Germany, and owned advanced world standards. This equipment has two types: rock-on-rock and rock-on-iron. Sand yield of "rock-on-iron" type is higher by 10-20% than that of "rock-on-rock" type.

Material falls down into high rolling impeller cavity vertically through the upper part of machine. Under great centrifugal force, it hits and crushes another part of material that distributing around the impeller with umbrella form. After hitting each other, they force a vortex between impeller and shell, and hit each other several times; finally smaller stone comes out, and goes to vibrating screen. Satisfactory material is transported by conveyor belt. However overlarge material will go back to VI Series Vertical Shaft Impact Crushers to be re-crushed. Otherwise, output sizes can be also adjusted according to customer's requirement.
