Application of Mobile Crusher in Highway and Railway Construction

Mobile crushers are widely used in highway and railway construction. Their core advantages lie in their flexibility, on-site processing, and high efficiency and environmental friendliness. Specific application scenarios and benefits are as follows:

1. Application in Highway Construction

Complex Terrain Scenarios

Mountainous Highway Construction: Highway construction in mountainous areas often faces the challenges of rugged terrain and widespread boulders. Mobile crushers can penetrate deep into mountainous areas, crushing boulders into crushed stone aggregate that meets roadbed requirements and can be directly used in highway subbase construction. For example, during the construction of the Guangxi Guiliu Expressway, mobile crushers were used to process boulders, eliminating the problem of indiscriminate disposal that impacts the landscape and driving safety while also enabling resource reuse.

Narrow Site Operations: Tracked mobile crushers are lightweight and compact, making them suitable for working in confined areas such as tunnel entrances and under bridges. They can be flexibly adjusted to meet crushing requirements in complex terrain.

Renovation and Overhaul Construction

Concrete Pavement Renovation: Traditional construction requires transporting discarded concrete blocks off-site, disposing them in landfills, and then purchasing new aggregate for paving, which is costly and time-consuming. Mobile crushers can crush concrete blocks directly on-site, and the resulting mixture can be used directly as a pavement base, saving manpower and material resources and reducing renovation costs.

Pavement milling material recycling: During major renovations, asphalt and concrete blocks produced by pavement milling machines can be crushed and screened by mobile crushers, becoming reusable pavement paving materials, thus achieving resource recycling.

Roadbed material crushing

On-site stone utilization: Highway construction requires a large amount of stone as roadbed filler. Mobile crushers can crush excavated stone on-site and use it directly as roadbed filler, reducing raw material procurement and transportation costs. For example, in road and bridge construction, crushing, screening, and utilizing leftover stone from the construction process can reduce both raw material costs and material transportation expenses.

2. Applications in Railway Construction

Ballast Stone Processing

Ballast Stone Quality Assurance: Ballast stone is a critical material for railway roadbeds, requiring functions such as cushioning train impacts, discharging water, and preventing roadbed subsidence. Mobile crushers can flexibly configure their main crushing units (such as jaw crushers, cone crushers, and impact crushers) based on ballast quality requirements, achieving precise control over coarse, medium, and fine crushing, ensuring uniform ballast size and strength.

Efficient Processing Capacity: Railway construction requires large quantities of ballast. Mobile crushers, with a processing capacity of 50-500 tons/hour, can quickly meet construction needs and shorten construction schedules.

Mobile Stone Processing

Stone Processing Along Railway Lines: Railway construction often requires quarrying stone along the line. Mobile crushers can be moved with construction progress, processing the stone locally, reducing transportation distance and costs. For example, in high-speed rail construction, mobile crushers can crush stone directly at the quarry and transport the finished material via conveyor belts into transfer trucks for off-site transport, improving construction efficiency.

3. Core Advantages of Mobile Crusher

Flexibility and Convenient Relocation

Mobile crushers are vehicle-mounted and self-moving, requiring no foundation for installation, making them easy to relocate. Tire-type crushers are suitable for road transport and flat sites, while track-type crushers offer enhanced off-road capabilities and can handle complex terrain such as mountains and swamps.

Integrated design, ready for immediate use

Mobile crushers integrate feeding, crushing, screening, and conveying functions. They can be put into operation immediately upon arrival, eliminating complex installation and commissioning processes and significantly shortening construction schedules.

Adaptable and versatile

Mobile crushers can be flexibly configured with different crushing units and screening equipment to suit different materials and output requirements. They are suitable for crushing materials of varying hardness, including ores, construction waste, and concrete.

Environmentally friendly, energy-saving and emission-reducing

Mobile crushers utilize advanced dust removal and noise reduction technology to effectively reduce dust and noise pollution. They are also equipped with energy-saving motors to reduce energy consumption, in line with green and environmentally friendly development concepts.
