Before this question can be addressed, we need to first determine if the material is friable. When we're talking about dry material processing, friable means a material will break before it bends. Thousands of materials are successfully crushed with impactors using many different equipment variations.
There are also many friable materials that aren't well suited to impact crush. Granite, for example, is friable but too hard, making impact crushing more expensive than other types of crushing. Stedman Machine has extensive experience crushing a variety of materials, a testing facility with full-sized equipment, and more than 10,000 test reports to help you determine what type of equipment is best for your needs.
