1. Relatively narrow width between the rails. After the covered Crushed Stone roadbed can be widened, and the locomotive tremendous pressure by rail, sleepers spread to the ballast, and then evenly distributed over the embankment, subgrade pressure will drop. The uniform dispersion of gravity from the rail to the ground, so as to ensure the safe operation of the train;
2. In the case of locomotives frequently shake, stone not only allows roadbed hard, and because of the relative compression between the stones do not cause depression deformable tread;
3. There is a gap between the stones, in the rain can drain quickly; so, the track will have excellent permeability, can greatly slow down the rotting sleepers；
4. Ballast can ensure the smooth operation of the train, so that passengers feel more comfortable. Without the ballast, the train will be very unstable, the body will be severely shaken, the train will not have a higher rate;
5. Gravel harder than pavement, and there are many gaps between the stones, if it is a concrete foundation, it is likely due to the thermal expansion coefficient of rail steel and cement of different damage. And due to the relative motion between the Gravel, it will ease the deformation caused by thermal expansion and contraction.
That is how so many of Gravel to get it?
Crushers can process river gravel, granite, basalt, quartz, iron ore, diabase, limestone, calcite, dolomite, barite, talc, gypsum, bentonite and other materials, and Gravel on the tracks is from the crushing crusher from.
For example, Liming company produced on a large jaw crusher is widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry, it has a variety of ores and medium-grained bulk material crushing have a good effect, especially for large pieces of quartz and other minerals. Wherein medium large jaw crusher is one of my company's main product, particularly in the design and production of large jaw crusher aspect, at home and abroad has been the absolute leader. Mainly used for a variety of ores and bulk materials of medium-grained broken, can be broken compressive strength of not more than 320Mpa materials, sub-coarse broken and fine broken two kinds. The complete series of product specifications, the feed particle size of 125mm ~ 750mm, is the primary crushing device of choice.
Liming Heavy Industry Science and Technology Co., Ltd. is a production of sand making machine, jaw crusher, cone crusher, sand and gravel production lines, such as mining machinery, research and development, production and sales of the joint-stock enterprises. Our products include: jaw crusher, the European version of the jaw crusher, impact crusher, single cylinder hydraulic cone crusher, mill, mobile crushing station series equipment and so on. Regardless of the ballast on the tracks, or the window of raw materials, as well as cosmetics, paper production are inseparable from broken equipment. Liming mining industry as China's leader, we will continue to develop new high-tech equipment, contribute to the community and our customers!
