What kind of crusher is used to create railway ballast?

A gyratory crusher is typically used to create railway ballast. This type of crusher consists of a large cone-shaped crushing head, which rotates eccentrically inside a crushing chamber. The gap between the crushing head and the inner wall of the chamber can be adjusted to regulate the size of the crushed material.

Railway ballast is typically created using a jaw crusher or a cone crusher. Jaw crushers are often used for primary crushing, while cone crushers are used for secondary crushing. The material is initially crushed by the jaw crusher and then further reduced by the cone crusher to the desired size for railway ballast. The resulting material is typically angular in shape, with a range of particle sizes that help provide stability and drainage to the railway track.

Here's some more information on the types of machines commonly used to create railway ballast:

  1. Jaw Crusher: A jaw crusher is a machine that uses a moving jaw to break down materials, including large rocks. The jaw crusher is commonly used as the primary crusher for railway ballast production, and it can crush materials up to 320MPa compressive strength.
  2. Cone Crusher: A cone crusher is a machine that uses an eccentrically rotating cone to crush materials. It is often used as a secondary crusher in railway ballast production, after the material has been initially broken down by a jaw crusher. Cone crushers are ideal for producing angular-shaped material with a range of particle sizes, which is important for providing stability to railway tracks.

Both jaw crushers and cone crushers are widely used in the production of railway ballast. The choice of machine depends on the specific requirements of the project, including the size of the material, the desired shape of the final product, and the capacity of the production line.
