The crusher is the workhorse of the hard rock crushing industry. A gyratory crusher uses a mantle that gyrates (rotates) within a cone shaped inner surface lined with wear resisting plates often called concaves. As the mantle gyrates within the crushing chamber, progressively approaching, and receding from, each element of the cone

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 . Material exits the crusher through the open side setting. Thus, the top size of the product is determined by the open side setting.

To obtain minerals suitable for age-dating and other analyses, it is necessary to first reduce the mineral-bearing rock to a fine, sand-like consistency. Reducing whole rock requires crushing, grinding, and sieving. Ideally, the reduced material should range in size from 80- to 270-mesh (an opening between wires in a sieve).
