Track ballast process flow

Raw materials are transferred to jaw crusher via vibrating feeder from hopper for primary crushing, then primary crushing products are transferred to impact crusher through belt conveyor for secondary crushing. The secondary crushing products will be transferred to the vsi stone crusher for shaping after which the finished ballast is mainly cubic, and separated to different sizes. The aggregate of suitable size will be transferred to the final product pile, while aggregate of unsuitable size to the crushing machine for re-crushing.

Advantages of KEFID track ballast production line

1. Product with needle plate type is no more than 5%. If crushed by Jaw Crusher and Impact Crusher, content of needle plate type is more than 10%, but with VSI Series Vertical Shaft Impact Crushers, it will be reduced to 4.7%.
2. The crushing and screening capability can be from 50 tons per hour to 600 tons per hour. The production improves 50% compared with using Impact Crusher as the final crushing processing.
3. With Impact Crusher and Vertical Shaft Impact Crusher, the consumption of wear-parts is reduced greatly in the whole process.
4. The final products are graded and separated according to customers' requirements and the size can be from 0 to 50 mm.
5. The advanced electric control panel can assure the whole process discharge smoothly, running reliable, operation easily and high efficiency in power consumption.
6. The duster is attached for the environment protection.

Main equipments of track ballast production line

Track ballast crushing and screening plant consists of the following equipments:
Vibrating feeder, Primary crushing machine: Jaw crusher, Secondary-crushing (fine crushing) machines: Impact crusher, cone crusher, Shaping machine: VSI stone crusher , Vibrating screen, Belt conveyor

Application of track ballast

Track ballast forms the trackbed for railway sleepers or railroad ties or the supporting bed for road. It should be strong, hard-wearing, stable, drainable, easy to clean, workable, resistant to deformation, easily available, and reasonably cheap to purchase. Good quality track ballast is made of crushed natural rock with particles between 28mm and 50mm in diameter. Angular stones are preferable to naturally rounded ones. Soft materials such as limestone are not particularly suitable; granite is one of the best raw materials of track ballast.
