What are the large machines used for crushing sand and gravel

As everyone knows, sand and gravel refer to a loose mixture of sand particles and crushed stone—that is, materials processed from various ores. They serve as the primary building materials for concrete and masonry structures in infrastructure, road construction, and water conservancy projects. But what are the large machines used for crushing sand and gravel?

What are these large machines for crushing sand and gravel called? They are known as large-scale sand and gravel crushers. Currently, there are various types available on the market. Based on different classification criteria, there are roughly a dozen types. Since sand and gravel vary in hardness, compressive strength, particle size, and other characteristics, and since each user has different requirements regarding output, product size, budget, and site conditions, the choice must be made based on actual circumstances. In comparison, jaw crushers, cone crushers, and hammer crushers are currently the most frequently used and effective options.

01 Jaw Crusher

Feed Size: ≤1200 mm

Capacity: 1–1000 t/h

Output Size: 10–350 mm

Suitable for sand and gravel with compressive strengths ranging from 147 to 350 MPa, it is generally used for primary crushing. Its deep crushing chamber eliminates dead zones, increasing throughput. Optimized motion parameters allow material to begin crushing in the upper part of the crushing chamber, while the large downward stroke ensures a higher crushing ratio. The wedge-type discharge opening adjustment mechanism allows for adjustable and uniform final product particle size. The integrated structure of the motor base and main unit simplifies installation and saves space.

02 Cone Crusher

Feed Size: ≤560 mm

Processing Capacity: 36–2,181 t/h

Final Product Size: 3–64 mm

This model is particularly suitable for high-hardness sand and gravel materials, serving as a secondary crusher for medium and fine crushing. Thanks to the laminated crushing chamber design and fixed-shaft structure, the concave liner requires no packing material and is easy to replace. The simplified structural design facilitates maintenance and adjustment, while the hydraulic chamber cleaning system minimizes downtime. Furthermore, each model offers multiple crushing chamber configurations, allowing users to select the appropriate chamber type based on specific requirements to better meet their needs. Additionally, the hydraulic motor adjusts the discharge opening, making operation more convenient and ensuring a more uniform final product size.

03 Hammer Crusher

Feed Size: ≤1000mm

Capacity: 30–3000 t/h

Final Product Size: 3–60mm

Suitable for medium-hardness and brittle sand and gravel materials, this machine crushes materials through the impact of hammers. Its modular design, featuring adjustable movable liners and a self-flowing material chute, enables one-step crushing, streamlining the process. The self-flowing chute design prevents re-crushing, resulting in minimal powder production and excellent particle shape. Additionally, larger models are equipped with a hydraulic hammer shaft extraction device, facilitating the replacement of hammers and shafts and saving time and labor.

The price of large-scale sand and gravel crushing machines is influenced by factors such as equipment type, specifications, brand, and functionality. Based on current market information, prices vary widely. Additionally, it is essential to consider whether additional costs—such as motors, shipping, and installation fees—are included. We recommend comparing quotes and services from different suppliers to comprehensively evaluate cost-effectiveness and make an informed decision.
