Granite stones can be used to make mortar and concrete according to different stone specifications. 1-2, 2-4, and 4-8 are common stone specifications. China's infrastructure construction cannot be stopped, and the domestic granite stone market has always been extremely hot, which has become a major driving force for the development of China's stone machinery industry.

Granite gravel is a high-quality building stone commonly used. This is due to the hard texture of granite, which is difficult to be eroded by acid or alkali or weathering. It is rich in granite resources and widely distributed. China has 9% of the land (about 800,000 square kilometers). They are all granite, and granite is widely used in highways, railways, high-grade buildings, and housing construction.

At present, the domestic crushing process of granite and the equipment technology of granite crushing production line have been quite mature. Shanghai Shibang Sand and Stone Project Department: I have a production line project for many granite production in China. The crushing production process of granite can generally use two-stage crushing production process. The first stage chooses jaw crusher. The second choice is the impact crusher. Of course, a circular vibrating screen can be used to separate stones of 1–2, 2–4, and 4–8 cm (or mm) to meet different construction needs.

The choice of impact crusher is very important. The impact crusher features good performance, high crushing ratio and excellent production effect. The choice of impact hammer is more important, because the impact hammer is a wear part that needs to be replaced frequently. The wear parts of the crusher directly affect the maintenance cost of the impact crusher in the later stage. It is recommended to choose Shanghai Shibang, a well-known domestic manufacturer of wear-resistant castings. Its wear-resistant parts such as toggle plate, impact hammer, crusher hammer, jaw plate and lining plate have been highly praised and won a good reputation.

In addition to granite crushing production, there are many sand and gravel production lines using different materials, such as river pebble, limestone, bluestone, and sandstone production lines, to meet the needs of various construction projects. For example, ordinary building construction can use relatively low‑hardness limestone to meet the requirements; while highway and high‑speed railway projects require harder river pebble gravel. As material properties differ, the corresponding production processes and equipment configurations are also different. China's largest sandstone production line contractor Shanghai Shibang Engineering Sand and Stone Project Department has many years of rich experience in the crushing production of various materials. The most economical and reasonable stone production line can be configured according to the site size and investment budget. device.
