Health Risks Associated with Exposure to Airborne Pollutants Arising From Quarrying and Aggregate Processing Airborne Particulate Matter (PM) Exposure and Health Risks Associated with APOs in Texas.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.
