How to choose suitable crushing equipment according to ore raw materials? As the basic material of engineering construction, sand and gravel aggregates are commonly used raw materials such as cobblestone, granite, diabase, basalt, limestone, etc. For different raw materials, the choice of crushing equipment is also different.

In the process of processing, suitable processing equipment should be selected according to the different raw materials.

First of all, when we classify raw materials, we can roughly divide the raw materials into hard stone and soft stone.

Hard stone is mainly represented by cobblestone, granite, and basalt, and its hardness is basically above 150Mpa. When processing this kind of raw materials, the choice of crushing equipment usually considers the use of jaw crushers and cone crushers, and then according to the requirements of the finished product, the impact crusher (shaping machine) is used for shaping to eliminate the stone in the crushing project. The resulting pin-shaped and internal cracks. Finally, a vibrating screen is used for sorting, and the crushed stones are sorted into finished sand and gravel aggregates of various specifications.

Secondly, when processing soft stone, such as limestone, sandstone and other stones with a hardness below 150Mpa, the choice of crushing equipment can be considered jaw crusher, impact crusher, heavy hammer crusher, and also according to the requirements of the finished product. With the use of impact crusher (shaping machine) for shaping, it can effectively improve the output of machine-made sand while eliminating the needle-shaped and internal cracks generated during the crushing process. The machine-made sand rate can usually reach about 60%.

One thing to note here is that the hardness of limestone varies greatly depending on its silicon content. We must pay great attention to the hardness of stone. If it is limestone with high silicon content, a cone crusher is required for crushing.

There are many ways to select sand and gravel aggregate processing equipment and process design. How to choose and match the specific needs needs to be comprehensively considered based on various factors such as the hardness, looseness, mud content, and finished product requirements of the unused raw materials.
