Impact crusher is a kind of quarry crushing machine which uses impact force to crush materials. Impact crusher crushes materials by impact force. When materials enter the blow bar area, they are crushed due to the high-speed impact of blow bar and are thrown to the impact plates on the rotor for secondary crush. Then the materials will be thrown back to the blow bar again for the third crushing. This process repeats until the materials are crushed to the required size and discharged from the lower part of the machine. The size and shape of the finished materials can be changed by adjusting the gap between the impact rack and rotor support. The machine employs self-weigh security device in its back frame.

When other objects enter the impact cavity, they will be forced out of the machine by the impact rack in the front and back of the machine. Impact crusher has the advantages of simple structure, keyless connection, unique impact lining board, high crushing efficiency, cubic shape product, adjustable particle size, simplified basalt crushing machine process and cost saving, which is the preferred equipment for materials with medium hardness such as granite, limestone and so on.Our company has large numbers of impact crushers for sale, which has complete models like vertical shaft impact crusher.

In recent years, during the transformation process of road renovation, especially the pavement laying and large square road improvement project, granite stone is widely used, from the beginning of last year, the city plaza and park pavement lying has been updated with granite stone as pavement laying material everywhere. In the modern decoration trend, its application is wide, because the granite not easily weathered, beautiful appearance color, which can be maintained for more than a century. Because of its high hardness, abrasion resistance, in addition to the simple pavement material, it also can be used as the most suitable material of high-level architectural decoration engineering, the ground outside the hall and open-air sculpture.
