What are the requirements for the production of stone for train tracks

Train tracks must be more familiar to everyone, there are countless cornerstones on the track, these stones seem inconspicuous but the track is indispensable to protect the operation of the track, the role of the track gravel what? What is the role of track gravel? What are the performance specifications for gravel? Today, I and you to learn to understand the above issues and roadbed stone processing technology, which crushing and crushing equipment used?

What is the significance of the role of the roadbed stone on the train track?

1. First of all, a large number of stones piled up together with the track below, can protect the train running in the flat and stable, dispersed train due to the weight and the force of the pressure generated by the track, buffer objects between the force of the damage caused by the reduction of friction, on the track and the body have a very good role in the protection.

2. Secondly, from a physical point of view, objects have the effect of thermal expansion and contraction, the natural track surface are so, plus the train itself is strong, on the road surface and the track of the force is greater, the track is very easy to receive the role of external forces and deformation or damage to safeguard the track's original position is very difficult to ensure that the train is prone to accidents in the process of the form of avoiding the effect of track heat and cold shrinkage in other areas can also be explained, such as bridges, houses, the outside of the house, and so on. Can be explained, for example, bridges, houses on the outside are mostly left with gaps or grooves is also an effective way to avoid physical expansion and deformation caused by weather or temperature changes.

3. Finally, stone crusher processed gravel in the railroad bed has a very good noise reduction and cooling effect, due to the irregular shape of the gravel, the noise, high heat absorption effect is far better than the smooth stone effect.

What are the performance requirements for railroad stone production? What principles are followed in the selection of stone crushing equipment?

Since we understand the importance of stone in the train track roadbed? Then the choice of stone is naturally higher than the general stone requirements, generally speaking, track stone more granite and other hardness of the stone, through the jaw crusher and other crushing devices processed into 20-70mm specifications varying from the stone, evenly and orderly stacked in the roadway and the track between the stone and the existence of gaps between the stone and the stone friction, so that the track has a certain degree of elasticity, reduce the impact of the locomotive and vibration! The working conditions of rolling stock and rails, sleepers and other components are improved, and the service life is prolonged. Track stone material selection on the nature of the stone has specific requirements, and thus the stone crusher type selection range is relatively narrow, in terms of the current stone crushing process, the processing of track stone is inseparable from the jaw crusher and other hard materials crushing equipment, with the track quality and performance continue to improve, but also need to stone crusher continue to improve and innovate to adapt to the needs of the development of the stone industry.

Track roadbed stone in the stone industry is a big market, but also a key difficulty, with the domestic short-range high-speed rail, road facilities continue to improve, the amount of engineering materials needed is also increasing, rail, subway, high-speed, airport and other projects projects belonging to the country and the people's common property, but also related to the people's livelihood and security of the major events in the selection of materials and crushing process should be perfect, China's land is vast and vast, but the development of technology With the advanced countries there is still a certain distance, the need for national enterprises to develop and innovate, have their own technical strength, stone crusher and other production enterprises should take this as a responsibility for the development of mining machinery industry and other stone and stone industry to make more contributions.
