Understanding the Basics

A vertical shaft impact crusher, commonly known as VSI, is designed for producing high-quality aggregates. It excels in producing fine materials with desired shapes. This makes it ideal for applications in construction, mining, and recycling.

How Does It Work?

The vertical shaft impact crusher follows a straightforward mechanism. Here's a breakdown of its working process:

  1. Material Feeding: The raw material enters the VSI through a feed hopper. Gravity pulls it down into the rotor.
  2. High-Speed Rotation: Inside the rotor, the material is accelerated to high speeds. This rotation can reach up to 80 meters per second!
  3. Impact and Crushing: The fast-moving material is thrown against a hard surface, typically a rock shelf or anvil ring. The impact breaks the material into smaller pieces.
  4. Material Classification: After the first impact, the smaller particles may be re-circulated. This ensures a consistent size and shape.
  5. Output: Finally, the processed material is discharged from the bottom. It’s ready for use or further processing.
