Vertical Shaft Impact crusher (VSI sand making machine) uses a unique rock on rock crushing method employing a high speed rotor with crushing chamber of the equipment, which only designed for the highway, high-speed railway, building, urban construction, hydraulic dam and concrete batching plant to supply excellent sand and aggregate. This crusher is widely used in crushing and reshaping of metallic and non-metallic ore, building material, artificial sand and all kinds of metallurgical slag.

The output size in fine or coarse aggregates can be controlled by adjusting velocity of the input material at 30-50mm and the distance between the end of the rotor and the impact point. Due to the unique arrangement, the final output can reach 60-520T/h, decreasing operating costs and consumption of wearing components.
