A gyratory crusher is a high-capacity, heavy-duty machine used in mining and industrial operations for primary crushing of large rocks and ores. It operates with a stationary outer shell (concave) and a conical inner crushing head that gyrates, compressing material between the two surfaces for continuous crushing. Ideal for large-scale operations, such as open-pit and underground mining, it efficiently handles abrasive, hard materials like granite and basalt, offering high reduction ratios and adjustable output sizes. Known for its durability and ability to process significant volumes, the gyratory crusher is essential in preparing raw materials for secondary crushing or milling while requiring regular maintenance to ensure optimal performance.
