As the old saying goes, “If you want to be rich, build a road first.”As an important transportation hub in the country, the railway is not only related to the speed and convenience of people’s travel today, but also closely related to the development of the country. This is related to whether we can carry forward our national capital and learn more advanced technologies. Therefore, the repair of railways is particularly important. So, what material is the railway ballast stone made of?What equipment is used in the processing process?Next, let’s explain in detail:
1. What material is the ballast stone?
Ballast stone refers to the gravel used to pave roads and railway subgrade, which mainly plays the role of supporting, cushioning, and draining.Ballast is made of Kaishan block stone broken and screened, and its needle-like index, flake-like index, weathered particles, surface cleanliness, etc. meet specific requirements before it can be put into use. According to the material properties and parameter indicators, it is divided into first-level unshaven and second-level unshaven according to regulations.
Granite and basalt are commonly used raw materials for ballast stone.Granite has the characteristics of hard texture, not easy to weathering, elasticity, and good drainage performance; basalt has the advantages of wear resistance, low draft, strong compressive resistance, low crushing value, strong corrosion resistance, and asphalt adhesion. Both are good cornerstones in railway and highway construction.
2. What equipment and process flow are required for the ballast stone crushing production line
The production of road ballast stone needs to be broken and screened before it can be obtained. It mainly includes three parts: coarse crushing, medium crushing, and screening. The production process is: raw material → Jaw crusher→Cone crusher→ Vibrating screen→Belt conveyor→ Road ballast gravel.
1. Jaw crusher (first-level coarse crushing)
Jaw crusher, also known as “Tiger mouth”, is the nemesis of large materials. It can handle a variety of stones with compressive particle sizes of not more than 320MPa. The production capacity of jaw crusher is between 160-1510t/h, covering a variety of models and configurations, such as PE jaw crusher, PEW European jaw crusher, C6X jaw crusher, etc., which can meet different production needs.
2. Cone crusher (secondary coarse crushing)
Cone crusher is a crushing equipment with strong crushing capacity, low operating cost, and medium and fine crushing of relatively hard rocks. It adopts the principle of laminated crushing for crushing treatment, and the finished sand and gravel are produced with uniform particle size; the spindle of the cone crusher adopts wear-resistant steel and cast steel technology, and the equipment has strong wear resistance and low failure rate.
3. Vibrating screen (screening equipment)
After the material is broken, it needs to be sieved through a vibrating screen. The commonly used screening equipment is: S5X vibrating screening equipment, Y series vibrating screening equipment, mobile screening machines, etc.
4. Belt conveyor (conveying equipment)
Belt conveyors are mainly used to transport loose materials or finished items. They can be transported in a single unit, multiple units or combined with other conveying equipment to form a horizontal or inclined conveying system. It has the advantages of large conveying capacity, simple structure, and easy maintenance.
Third, the applicable operating environment of railway ballast stone processing equipment
1. When the output is large and the site area is sufficient , a combination of jaw crusher and impact crusher and vibrating screen can be selected;
When this combination realizes mass production of ballast stones, the stone product has a better grain type and a large output. Working together with the old partner can greatly improve the crushing efficiency.
2. When the output is general and the process requirements are simple , the hammer crusher and vibrating screen can be directly selected;
The performance advantages of the hammer crusher are relatively special. It can achieve the processing effect of the two equipment of other programs with its own strength, and it has beautiful particle shape, strong crushing capacity, large crushing ratio, and very cost-effective.
3. When the site area is small and the stone raw material storage location is relatively dispersed , a mobile crusher can be used to process the stone raw material;
The machine can be combined according to the actual situation of the user, and it is convenient and flexible to move, advanced and practical technology, energy-saving and environmentally friendly in the production process, and it is used frequently in many job sites that require mobile crushing.
In fact, in the actual production and processing process, customers will always encounter such and such problems. If the above-mentioned solutions differ from the customer’s situation in the practice process, you can choose to contact the manufacturer’s technical engineers to design the crushing plan for you for free.
