Ballast Production Line

Railway track ballast is packed between, below, and around the ties. It is used to facilitate drainage of water, to distribute the load from the railroad ties, and also to keep down vegetation that might interfere with the track structure. This also serves to hold the track in place as the trains roll by. Good quality track ballast is made of crushed natural rock (granite, quartzite) with particles between 28mm and 50mm in diameter; a high proportion of particles finer than this will reduce its drainage properties, and a high proportion of larger particles result in the load on the ties being distributed improperly. How can we get railway track ballast? Zenith can offer you the best solution in the world.

Track ballast is typically made of crushed stone or rocks. It provides a supporting bed for rail tracks, and road. A good ballast 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, as these interlock with each other, inhibiting track movement. Soft materials such as limestone are not particularly suitable, as they tend to degrade under load when wet, causing deterioration of the line; granite, although expensive, is one of the best materials in this regard.

Track ballast crushing and screening plant

Ballast crushing and screening plant is consist of jaw crusher, impact crusher, cone crusher, VSI stone crusher, vibrating screen, and belt conveyers. Jaw crusher is used as primary crusher, impact crusher and cone crusher is used for fine crushing, the vsi stone crusher is used for stone shapping.

These machines are of advanced structure, good performance, high reliability (such as jaw crusher achieved EU CE Certificate), and praised by many customers home and abroad. The crushing and screening capability can be from 50 tons per hour to 600 tons per hour. The size of crushed stones can be from 0 to 50 mm. The classification of size of crushed ballast can be set and adjusted according to customers different requests.

Ballast crushing and screening process

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

The sizes of final products will be graded and separated according to customers’ requirements, and the duster will be attached for the sake of environment protection. The track ballast production line are reasonable combined with different crushers and have compacted special crossing distribution in their material processing flow design, so that they are small foot printed of fields, high quality in crushed products, low in quarry dust and they will give you high reward for your investment. Their advanced electric control panel can assure the whole process discharge smoothly, running reliable, operation easily and high efficiency in power consumption
