Description
420 Cone crusher is a type of mechanical crusher commonly used in the mining and aggregate industries. It falls under the category of a compression crusher, which works by squeezing the material between a moving piece of steel, called the mantle, and a stationary piece, called the bowl liner. This process breaks the material down into smaller pieces.
Here’s a basic overview of how a 420 Cone crusher works:
- Material Feed: Large pieces of material are fed into the top of the cone crusher.
- Crushing Chamber: The interior of the crusher consists of a concave-shaped bowl liner and a mantle. The mantle is a moving piece that gyrates within the bowl liner, applying pressure to the material.
- Crushing Action: As the mantle gyrates, it compresses the material against the bowl liner, effectively crushing it. This process is repeated until the material becomes small enough to pass through the narrow gap between the mantle and the bowl liner.
- Product Size: The crushed material exits the bottom of the crusher as smaller-sized pieces.
Cone crushers are known for their efficiency in producing cubic-shaped aggregates and are commonly used in secondary, tertiary, and sometimes quaternary crushing stages. They are widely employed in the mining, construction, and aggregate industries for crushing hard and abrasive materials such as granite, basalt, and ores.
Different manufacturers offer various models and sizes of cone crushers, each designed for specific applications and production requirements. It’s important to choose the right type and size of cone crusher based on the material to be crushed and the desired end product specifications.
