A cone crusher is a heavy-duty crushing machine used in mining, aggregate, and construction industries to reduce the size of hard and abrasive materials such as rock, ore, and gravel.
A cone crusher has a fixed outer bowl (concave) and a moving inner cone (mantle). Material is fed from the top; as the mantle rotates and oscillates, it compresses and crushes the material against the concave. The crushed material exits from the bottom.
