Cone crushers are essential secondary and tertiary crushing equipment in mining and aggregate production. The mantle and concave are the most critical wear parts inside a cone crusher. This article explains how cone crushers work, where they are used, and how the choice of mantle and concave material (Mn13%, Mn18%, Mn22%), tooth pattern, and chamber design directly affects crushing efficiency, product shape, and cost per ton. A practical selection guide based on rock type and production goals is provided.
