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
