A cone crusher is a type of crushing equipment used in mining and construction to reduce the size of rocks and minerals. Here's a basic overview of how it works:
Feeding Material: Raw materials are fed into the crusher from the top through the inlet.
Crushing Chamber: The materials enter the crushing chamber, where a rotating cone (mantle) is positioned inside a stationary outer shell (bowl). The space between the mantle and the bowl is where the crushing takes place.
Eccentric Motion: The mantle is mounted on an eccentric shaft, which provides an oscillating or gyrating movement that crushes the material. As the mantel moves, it crushes the rocks against the bowl liner, breaking them into smaller pieces.
Compression: The primary mechanism of crushing in a cone crusher is compression. The rock material is squeezed and broken into smaller pieces as the gap between the mantle and bowl liner narrows and widens.
Discharge: Once the material is crushed to the desired size, it exits the crusher through the bottom discharge opening.
Adjustment: Modern cone crushers come with hydraulic adjustment systems that allow operators to alter the size of the discharge opening, thus controlling the final output size.
Safety features and design improvements in modern cone crushers also ensure efficient operation and longevity of the equipment.
