A cone crusher is a type of machine used in the mining and construction industries to crush rocks and ores. It operates by using a rotating cone that moves within a larger, stationary cone. As the material enters the crusher, it is squeezed and crushed between the two cones, producing smaller, more manageable pieces. These machines are known for their efficiency and ability to produce a uniform product size. Cone crushers are commonly used for secondary and tertiary crushing, making them essential in the production of aggregates for construction and road building.
