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 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抯 different
requests.
Process of the railway track ballast production line
Big size
stones are transferred to primary crusher through vibrating feederfrom hopper
for first crushing, then the crushed materials are transferred toimpact 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.
With its high quality products such as , , , , , Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
