Railway track ballast

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.

　Detailed production line description

Ballast crushing and screening plant consist of jaw crusher, cone crusher, impact crusher, VSI stone crusher, vibrating screen, and belt conveyers, 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 product can be from 0 to 50 mm. The classification of size of crushed product can be set and adjusted according to customer’s different requests.

　Process of the railway track ballast production line

Big size stones are transferred to primary crusher through vibrating feeder from hopper for first crushing, then the crushed materials are transferred to impact crusher through belt conveyor for secondary crushing. The materials crushed will be transferred to the vibrating screen, and separated to different sizes. The aggregate with suitable size will be transferred to the final product pile and aggregate with unsuitable size will be transferred to the impact crusher for re-crushing. This forms a closed and manifold cycles. 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.
