What is vsi in mobile stone jaw crusher

VSI stands for Vertical Shaft Impactor. In the context of mobile stone jaw crushers, a VSI crusher is a device that utilizes high-speed rotating shafts to crush rocks by throwing them against hard surfaces to break them down. It's an alternative type of crushing equipment which offers several benefits:

1. High Efficiency: VSI crushers are renowned for their ability to produce high-quality, cubical-shaped aggregates with excellent particle shape.
2. Versatility: These crushers can handle a variety of materials, from soft, highly abrasive to hard and refractory rocks, making them highly versatile.
3. Energy Efficiency: By relying on inter-particle crushing rather than direct impact, VSI crushers can reduce energy consumption while providing high-capacity output.
4. Cost-Effectiveness: They often lead to reduced wear costs compared to other types of crushers due to the nature of the crushing process.

Typically, VSI crushers are used in conjunction with mobile stone jaw crushers to produce aggregate for construction and infrastructure projects, among other uses. The combination of both types of crushers offers the flexibility to produce various size and shape of crushed material required.
