subject: Ballast Crusher Used For Track Ballast Production Line [print this page] Ballast crusher is used for track ballast production line in the ballast crushing plant.
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.
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.
Ballast production flow chart
In order to get the eligible ballast stones for highway, railway and road building, quarry mining usually use the complete ballast crushing and screening plant. In ballast crushing and screening plant, stones firstly enter into jaw crusher for primary crushing, then through belt conveyor evenly enter into impact crusher or cone crusher for fine crushing. Finally, through vsi crusher stones mainly are cubic in shape. Vibrating screen is used as screening machine to screen out the different size of ballast. The ballast that are unqualified return to the crushing plant for crushing again.
Advantages of SBM 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.
