Rubble is an irregularly shaped stone obtained after blasting or manual excavation of rocks. It is often used for masonry foundations, stifles, walls, dams, retaining walls, etc. It can also be used to prepare rubble concrete. Jaw crusher is the responsible equipment for rough stone road crushing. So, what are the factors that affect the output of jaw crusher?
    1. Material hardness
    The higher the hardness of the raw materials crushed by the jaw crusher, the more difficult it is to crush, the more severe the abrasion, the slower crushing speed, and the lower the output. Therefore, during the crushing operation, I need to pay attention to selecting rubble materials with moderate hardness for crushing.     2. The amount of fine powder in the material
    The more fine powder contained in the material before crushing, the er the impact on the output of the finished product. These fine powders are easy to adhere and affect the transportation, thereby reducing the output of the jaw crusher. On the other hand, the fine powder cannot be used as a finished stone. Use, reduce the overall output of finished stone products. It is recommended that materials with high fine particle content should be screened in advance, and fine powder should be screened out from the materials as much as possible to avoid affecting the normal production of the jaw crusher.
