Compared with the traditional equipment, the cone crusher is very reasonable in both the exterior design and the internal structure design. It combines a lot of *techniques and also judges the domestic road gravel specifications to ensure the size of the gravel produced. Uniform and reasonable gradation. The advantages of concrete cone crusher used in highway gravel are as follows:
    1. Good grain shape: The crushed stone material processed by the cone crusher adopting the laminated crushing principle has beautiful grain shape, uniform size and high utilization rate;     2. One machine for multiple purposes: the modular design of the cone crusher can realize the conversion of coarse, medium and fine crushing by changing the cavity type. Combined with the principle of lamination crushing, it can better meet the needs of medium and fine crushing processes. Greatly improve the efficiency of crushing production;
    3. High wear resistance: all parts of the whole machine are made of high manganese steel, such as crushing wall, rolling mortar wall, etc., combined with the change of the crushing cavity and the protection of the material layer during lamination crushing, reducing the wear of the cone crusher;
    4. High safety: With spring safety device, when unbreakable foreign matter appears in the crushing chamber or the equipment is stained, the cone crusher can automatically increase the discharge port to discharge the foreign matter and ensure the safety of the equipment.
