A gyratory crusher is a type of primary crusher that is used in mines and ore processing plants to crush rocks and ores into smaller sizes. It consists of a concave surface and a conical head, with the head being inclined at an angle to the concave surface. The crushing action is caused by the closing of the gap between the concave surface and the mantle, which is located on the central vertical shaft of the crusher.
One of the primary advantages of the gyratory crusher is its high capacity. It is capable of handling large quantities of material at a time, making it a popular choice for mines and large-scale processing plants. Additionally, it is able to process a wide range of materials, from soft to hard and abrasive, without the risk of damage to the crusher.The gyratory crusher is also known for its reliability and durability. It is designed with a robust construction that can withstand heavy-duty use and high stress loads. Its parts are made of high-quality materials that are resistant to wear and tear, and are designed to provide a long service life with minimal maintenance.
Another advantage of the gyratory crusher is its safety features. Unlike other crushers, the gyratory crusher has a spider bearing assembly that is located on top of the main shaft. This design prevents material from entering the bearing and causing damage to the crusher. Additionally, the crusher is equipped with hydraulic systems that can be used to adjust the gap between the mantle and concave surfaces, allowing for safe and precise adjustments to be made while the crusher is in operation.
In terms of operation, the gyratory crusher is relatively simple. Material is fed into the crusher through a hopper or conveyor belt, and is then crushed between the mantle and concave surfaces. The crushed material is then discharged through the bottom of the crusher, where it can be further processed or transported for use.
The gyratory crusher is a powerful and reliable primary crusher that is widely used in mines and ore processing plants. Its high capacity, durability, and safety features make it a popular choice for handling large quantities of material in demanding environments. With its simple operation and low maintenance requirements, it is an excellent investment for any operation that requires a reliable and efficient primary crusher.
