What machine is used for tunnel muck to crushed stone processing？

GME provides complete equipment and customized solutions from primary crushing to screening, suitable for granite, limestone, tuff and other tunnel muck, meeting the needs of infrastructure projects for different sizes of aggregates.

1、C6X Series Jaw Crusher (Primary Crushing)

As the first stage in tunnel muck processing, the C6X jaw crusher is specially designed for large and high-hardness tunnel muck. It can handle feed size up to 1300mm, with a large crushing ratio and high output. It can crush large tunnel muck directly to 200–400mm, laying a solid foundation for secondary and fine crushing.

With heavy-duty structure and wear-resistant materials, it offers much better stability and service life than ordinary jaw crushers when dealing with hard rock such as granite and basalt. It is the standard primary crushing equipment for large tunnel muck projects.

2、HST Single-Cylinder Hydraulic Cone Crusher (Secondary & Fine Crushing)

This is the core secondary crushing machine for medium-hard and above tunnel muck. The discharge opening is automatically adjusted via single-cylinder hydraulics, allowing precise control of output size at 30–60mm. The optimized crushing chamber reduces over-crushing, resulting in uniform particle shape with few flat or elongated particles.

Compared with traditional cone crushers, the HST reduces energy consumption by 15% and is easy to maintain, making it ideal for continuous production. It is the mainstream secondary crusher for tunnel muck lines with 200–500 tons per hour capacity.

3、HPT Multi-Cylinder Hydraulic Cone Crusher (Fine Crushing & Shaping)

For high-hardness, highly abrasive tunnel muck such as granite, the HPT multi-cylinder cone crusher delivers stronger crushing force and higher finished product rate. Discharge size can be as fine as 5–20mm, with excellent particle shape and reasonable gradation.

Its multi-cylinder hydraulic protection system automatically removes uncrushable materials, resulting in low failure rate. It is widely used in high-speed railway, highway and other key projects that demand high-quality crushed stone.

4、VSI6X Vertical Shaft Impact Crusher (Sand Making & Shaping)

The VSI6X is essential when turning tunnel muck into manufactured sand or premium aggregate. It uses a combined “rock-on-rock + rock-on-iron” crushing principle to deeply shape the pre-crushed tunnel muck.

Finished aggregate has round particles, with flat and elongated content below 5%. It can also produce 0–5mm manufactured sand, realizing multi-purpose use of one material. The machine features long wear-part life, low operating cost, and supports both dry and wet processing.
