With the rapid development of road engineering in my country, the proportion of tunnels and excavated roadbeds in mountainous road engineering has continued to rise. In some newly built roads, this proportion has exceeded 70%. In the process of tunnel and roadbed excavation, a large amount of tunnel slag and stone slag will inevitably be generated. If these wastes are not reasonably utilized, it is often necessary to set up a special waste dump, which not only occupies land resources, but also may affect the environment.

Tunnel slag crushing and sand making equipment

Therefore, processing tunnel slag into sand and gravel aggregate is an economical and environmentally friendly way of utilization. This article will introduce the design configuration of the tunnel slag crushing production line and its equipment selection.


Production line configuration plan

Depending on different processing conditions, the tunnel slag crushing production line can adopt 2-4 crushing processes:


Second stage crushing: equipped with jaw crusher and impact crusher or cone crusher, it can effectively produce 5-31.5mm building gravel.


Third stage crushing: Add a sand making machine on the basis of the second stage. In addition to different specifications of gravel, it can also produce 0-5mm machine-made sand.


Four-stage crushing: A more complex configuration, usually including jaw crusher, single-cylinder cone crusher, multi-cylinder cone crusher and sand making machine, suitable for projects with higher requirements for particle shape.

Each production line also needs to be equipped with auxiliary equipment such as feeder, vibrating screen, belt conveyor, etc., which can be adjusted according to actual conditions.


The importance of resource reuse

After reasonable processing, tunnel slag can be used to fill the roadbed, reducing dependence on purchased gravel and reducing construction costs. For example, the Duyun-Anshun Expressway project successfully used a large amount of tunnel slag to fill the roadbed, which has been filled for more than 1.5 kilometers, saving a lot of resources.


Processing technology and equipment selection

The processing of tunnel waste slag mainly includes crushing, screening and sand making. The key equipment selection is as follows:


Fixed equipment: such as jaw crusher and impact crusher, suitable for large-scale, fixed-site processing sites.

Mobile equipment: convenient for flexible processing in different sites, suitable for situations where raw materials are not fixed.


For medium and high hardness rocks, it is recommended to use a three-stage crushing process, while for medium and low hardness rocks, a two-stage crushing process can be used.


Quality control and particle size grading

In order to ensure the quality of sand and gravel aggregates, quality control must be strengthened, mainly including:


Raw material selection: During the excavation process, waste rocks with good integrity and performance that meet the requirements are preferred for processing.


Particle size grading: Ensure that the grading of each level of processing is stable, the screen size needs to be customized according to requirements, and adjust the ratio in time to meet the design standards.


Conclusion

Through scientific design and reasonable configuration, tunnel slag can not only effectively reduce the impact of waste on the environment, but also be converted into high-value sand and gravel aggregates to promote the recycling of resources. With the advancement of green highway construction, the processing and utilization of tunnel slag will receive more and more attention, promoting the sustainable development of my country's road engineering.
