The VSI's high cubical fracture percentage maximizes first-pass product yield and produces tighter particle size distribution. It has a high-throughput capacity, ideal for beneficiation (elimination of soft material). Properly configured, the VSI accepts highly abrasive materials, and it is designed for simple operation and maintenance.

The Sides of the Crusher. A cone crusher has two sides: an open side and a closed side. As the material crushes, the particles that are small enough to fit through the open side fall through the space between the mantle and the concave. As the mantle gyrates, it creates a narrow point and a wide point.
