The rotor, being the heart of the Vertical Shaft Impactor (VSI), is designed for high capacity with low power consumption. The wear parts for a VSI rotor are contained both within and on the outer surfaces of the rotor. Different parts have material technology to resist either impact or abrasive wear. The selection of the correct wear parts for the application required is fundamental to ensuring the desired performance.
