What Are Gyratory Crushers?

Gyratory crushers are heavy equipment used in the mining and quarrying industries. They are cone-shaped machines that use centrifugal force to grind rocks and other materials. Gyratory crushers are larger than cone crushers and can handle larger rocks than other types of rock crushers. They are used in mines and quarries to break apart large rocks into smaller ones. Gyratory crushers are generally more robust than cone crushers and are well equipped to handle larger feed sizes.

Gyratory crushers can be divided into two categories: cone and impact gyratory crushers.

Cone gyratory crushers are the most common type and are used to crush medium to hard materials. They work by forcing the material to fall between two cone-shaped crushing surfaces, which effortlessly reduces the size of the material. Impact gyratory crushers are used to crush harder materials and are often used in mining and quarrying operations. They work by smashing the material against a rotating hammer, which reduces the size of the material into a more workable mixture.

Both cone and impact gyratory crushers can be rented, which is a good option for those who only need them for a short period of time.

How Do Gyratory Crushers work?

The gyratory crusher is a heavy machine consisting of an iron or steel frame with an actuating mechanism and a cone-shaped chamber lined with wear-resisting plates. A steady rest, called a spider, supports the upper part of the machine. The main shaft passes through the eccentric journal at its lower end, which offsets it from centerline of the crusher. At its upper end, it connects to a crushing head or mantle via a heavy nut that allows for some vertical movement.

Gyratory crushers are often the starting point for hard rock mining. The machines reduce the size of aggregate to a maximum of about one-tenth of its original size. Some plants use Bradford Breakers and Mineral Sizers, but others rely on gyratory crushers. Ore from mines typically arrives at the plant by haul trucks, which discharge into a feed hopper at the upper level; crushed ore is then discharged from the bottom shell assembly. In some cases, a grizzly feeder may be used instead of a conveyor belt; this allows undersize ore to be screened out rather than crushed by the gyratory crusher and then it is transferred directly to an output conveyor.

What Are The Benefits Of Gyratory Crushers?

Gyratory crushers have many benefits compared to other types of rock crushers. Their benefits include:

High Output Volume

They can process more volume per hour, and they can handle larger rocks. This makes them a better option for larger projects.

Consistent Product

Additionally, gyratory crushers can produce a more consistent product size, which is important for projects that may have specific needs for the aggregate mixtures they require.

Precision

Gyratory crushers are often chosen due to their improved ability to break down tough to work with materials into an aggregate solution that meets the specification of your project.
