A cone crusher is a type of equipment used for size reduction of minerals and aggregates. It works by squeezing the material between an eccentrically rotating mantle and a stationary concave or bowl-shaped liner.

When the cone crusher is turned on, the mantle rotates around the axis of the crusher, and the concave or bowl liner stays stationary. The rock material is fed into the crusher through the top of the cone and is compressed between the mantle and the bowl liner. As the material is crushed, it falls through the bottom of the crusher.

The size of the crushed material is determined by the gap between the mantle and the bowl liner, which can be adjusted by moving the bowl liner up or down. This allows for the desired product size to be achieved.

Cone crushers can be used for a variety of applications, including crushing hard and abrasive rocks, ores, and minerals. They are commonly used in the mining, construction, and aggregate industries.

It's worth noting that there are different types of cone crushers available, each with their own unique features and advantages. For example, some cone crushers are designed to operate at a fixed setting, while others have adjustable settings to optimize performance for specific applications.
