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

Usages of Vertical Shaft Impact Crusher:
1. It is used for producing building aggregate, concrete, aggregate for road surface and roadbed, asphalt concrete and cement concrete.
2. It is also used for sand making and shaping in the field of engineering such as water conservancy, hydroelectric power, high-class highway, high-speed railway, passenger special line, bridge, airport pavement, municipal works and high-rise buildings.
3. It is used widely in many industries such as building materials, metallurgy, chemical engineer, mining, refractory materials, cement, etc.
4. It is used for producing glass raw materials, quartz sand and other high purity materials.

Working Principle of Vertical Shaft Impact Crusher:
Material falls down into the high rolling impeller cavity vertically through the upper part of the machine. Under great centrifugal force, such part of material will hit and crush another part of material that distributing around the impeller. After hitting each other, those two parts of material will force a vortex between impeller and shell. Several times later, finally smaller stone comes out, and goes to vibrating screen. Satisfactory material is transported by conveyor belt. However overlarge material will go back to Vertical Shaft Impact Crusher to be re-crushed. Otherwise, output sizes can be also adjusted according to customer's requirement.

Performance characteristics:
1. simple and reasonable structure, low operation cost
2. high broken rate, energy-saving
3. fine and coarse grinding function, easy maintenance
4. the moisture content of materials ,the impact of small, with water up to about 8%
5. more suitable in broken hardware, special hardware materials
6. cubical final products, packing density, and a very small iron contamination.
7. lower noise, below 75 decibels,less dust pollution.
