Granite is a widely used construction material, known for its uniform structure, high hardness, and strong wear resistance. As a type of high-quality durable aggregate, it is commonly applied in infrastructure projects such as highways, railways, airports, and high-rise buildings. Due to its rigidity and abrasion resistance, selecting the right crushing equipment and designing a suitable crushing process are crucial to ensure productivity and reduce operating costs.

Primary Crushing: Jaw Crusher

In the first stage of granite crushing, a jaw crusher is typically used for coarse crushing. This machine features a large feed opening and powerful crushing force, which enables it to handle big granite blocks easily. The output from the jaw crusher usually ranges from 100mm to 300mm, depending on the model and the settings. Its high efficiency and low cost make it the ideal choice for primary crushing of granite.

Secondary & Tertiary Crushing: Cone Crusher

After primary crushing, the semi-finished material enters a cone crusher for secondary and fine crushing. Cone crushers are especially suitable for handling high-hardness materials like granite. They provide stable performance, uniform output size, and excellent protection against overloading and wear. Depending on the production requirement, multi-cylinder or single-cylinder hydraulic cone crushers can be selected to enhance crushing efficiency and product quality.

Shape Optimization: Impact Crusher or Sand Making Machine

For specific projects where aggregate shape is critical—such as in roadbase and high-performance concrete—an impact crusher or sand-making machine (such as VSI) may be added at the end of the process. These machines help refine the shape of the crushed granite, producing well-graded, cubical particles that meet the strictest standards of construction material.

Customized Crushing Solutions

Depending on customer requirements, production capacity, and finished product specifications, the granite crushing line can be flexibly configured. Mobile crushing stations (tracked or wheeled types) can also be deployed in areas where relocation is frequent, such as construction waste disposal or temporary projects in remote locations.
