What kind of special crusher is used for the stone used in train tracks?

The production of railway ballast requires strict selection of crushing equipment. Jaw crushers are suitable for coarse crushing, cone crushers are suitable for medium crushing, and mobile crushers are suitable for small sites. Choosing the right equipment combination can ensure the quality of ballast.

As an important national infrastructure and popular means of transportation, the role of trains is particularly important, especially during holidays. The safety and smooth operation of railways are inseparable from the ballast under the track. These crushed stones not only support the rail sleepers and enhance the stability of the rails, but also disperse vibrations and enhance drainage functions. The production of railway ballast has very strict requirements on equipment. So, what kind of crusher is suitable for railway ballast?

Ballast Crushing Equipment

What is ballast?

Ballast is a crushed stone material used for laying roadbeds in railway and highway construction. Commonly used ballast raw materials include granite and basalt. Granite is hard and not easily weathered, and has good elasticity and drainage performance; basalt is wear-resistant, compression-resistant, and corrosion-resistant, and is suitable as a high-strength load-bearing material.

Railway ballast stone production process

The production of ballast stone requires multiple steps such as crushing and screening. The specific production process includes:

Coarse crushing: Use a jaw crusher to process large pieces of stone.

Medium crushing: Use a cone crusher to further crush the coarsely crushed stone.

Screening: The crushed stone is screened through a vibrating screen to ensure that the specifications are met.

Ideal equipment for railway ballast stone processing

Jaw crusher: This is the preferred coarse crushing equipment for large pieces of stone, suitable for processing stones with a compressive strength of no more than 320MPa. The jaw crusher, with its "V"-shaped crushing chamber design and dead zone-free structure, ensures smooth material processing and is easy to operate, suitable for sites with high production efficiency requirements.

Cone crusher: Cone crusher is an ideal medium crushing equipment for basalt and granite with higher hardness. It adopts the principle of lamination crushing, and the finished product has uniform particle size, high output, wear resistance and long service life.

Mobile crusher - efficient choice for small sites

For limited sites or scattered stone raw materials, mobile crusher is a flexible choice. It can be moved at any time, suitable for changing production environments, and can produce finished products of various specifications at the same time, which is environmentally friendly and energy-saving, greatly improving the operation efficiency.

Conclusion

The production of railway ballast has very high requirements for crushing equipment. Choosing a suitable equipment combination, such as jaw crusher plus cone crusher, or using mobile crusher when conditions permit, can ensure the production of railway ballast that meets the requirements.
