Gyratory Crushing Action. Designs of the breaking faces vary with manufacturer. As a result, the product size distribution varies. When the feed drops into the crusher, the mantle squeezes the rock against the concave surface. When the mantle moves away and the rock drops down further and subject to additional crushing during the next cycle .
