Cobblestone is also river pebble, the main component is silicon dioxide, but also contains iron oxide, manganese, copper, aluminum and other elements and compounds. Cobblestone is a Zhongxin building material. Because of its hard quality, good compression resistance, wear resistance and corrosion resistance, it is a popular Zhongxin building material and is widely used in construction and road construction industries.
    Cobblestone go through a crushing process before being used in various industries to reach a suitable particle size before it can be used. However, it is hard and wear-resistant, resulting in relatively difficult processing, and higher requirements on the rigidity of the cobblestone crushing processing equipment. The coarse crushing of pebbles usually uses a jaw crusher.     1. The jaw breaking of low-cost investment and high-yield return
    Rough pebbles crushing equipment-jaw crusher, can crush high-hardness river pebbles, with high local pressure, thick jaws, large span of jaw teeth, large bending moments, and narrow and deep jaws. Because the pebbles are hard in quality, have natural characteristics such as compression resistance, wear resistance and corrosion resistance, they have high requirements for the abrasion of the equipment, and the jaw crusher is just right to meet this need.
    Second, the working principle of stone crushing
    The cobblestone jaw crusher adopts the theory of rock-to-stone crushing. The crushed materials have less wear on the machine, and the main wearing parts are made of high wear-resistant materials. They are made through a certain treatment process, and the loss in production is better. Each component has a long service life. During the entire crushing process of cobblestones, the materials will be impacted and crushed by themselves without direct contact with the metal components in the equipment. The ingenious airflow self-circulation inside the vortex cavity eliminates dust pollution and reduces dust pollution in production. The crushing machinery is more productive.
