impact crushing work index

As a basic rule, impact crushing is suitable for rocks with a low work index (<12) as well as low silica (<20%) and moisture levels (<5%). Rocks with these characteristics are soft and non-abrasive, and easily broken within the crushing chamber, keeping wear rates at a minimum, and producing high reduction ratios with a better-shaped end product.
