With the rapid development of social economy, a large number of domestic mining equipment have emerged rapidly, which has also driven the development of original equipment. The stone production line industry is the main production line equipment used for sand and gravel production. Sand and gravel production is mostly used in engineering construction. Now it can also be used to build infrastructure, mainly to provide construction stones for highway construction. Most of the stones required for highway construction are in the shape of cubes. To produce ideal sand and gravel aggregates, a complete stone production line must be equipped. In the stone production line, the crushing principle of the cone crusher adopts the laminated crushing principle, which not only improves the crushing output and efficiency, but more importantly, it improves the product particle shape. Most of the products have a cubic structure. It reduces the need for needle-shaped materials and is very suitable for the material requirements of highway construction. Generally speaking, cone crushers are used in metal and non-metal mines, cement plants, construction, metallurgy, transportation, sand and gravel aggregate production and other industries. It is precisely because of the various characteristics of the cone crusher that the cone crusher is used in the highway sand and gravel aggregate production process.
