A Gyratory Crusher is a type of primary crusher used in mines and ore processing plants. It consists of a cone-shaped main body that is open at the top, where material is fed into the crusher through a hopper. The crushing action is provided by the gyrating movement of the main shaft, which is located inside the main body and suspended by a spider arm assembly.
The main shaft is supported at the top by a bearing assembly, and at the bottom by eccentric bushings. As the main shaft rotates, the mantle, which is attached to the main shaft, moves eccentrically, crushing the material against the concave liners, which are fixed inside the main body.
The crushed material then exits through the narrow space between the mantle and concave liners, and falls down to a lower level for further processing. The gyratory crusher is typically used for large-scale operations and can handle high capacity throughput.
Some advantages of a gyratory crusher include its ability to handle hard and abrasive materials efficiently, its relatively low maintenance requirements, and its ability to provide a consistent product size. However, they are generally more expensive than other types of crushers and require a larger footprint.
Overall, the gyratory crusher is commonly used in mining, construction, and aggregate industries as a primary crusher for crushing various types of rocks and ores.
