The jaw crusher jams the material and cannot come to the ore, because the jaw crusher is in the process of working, the ore materials with higher water content enter the crushing cavity, and the crusher breaks the water-containing materials into small pieces and turns them into small pieces. The viscosity of the materials will stick to each other and be blocked between the two jaws in the crushing cavity, causing material jams; it may also be that the crushed materials are mixed with thicker clay, causing The material is stuck in one piece and blocked in the crushing cavity, causing material jam.
    In view of this situation, you can try the following methods:     1. Pre-screening, pre-washing, and ore blending can be used to control moisture, but some ores are difficult to process;
    2. It can also be screened in advance, and the discharge port can be appropriately enlarged to increase the discharge efficiency;
    3. It can also reduce the spindle speed and enlarge the discharge port;
    4. The discharge opening can also be adjusted, but the angle should not be too flat.
    On the other hand, before using the jaw crusher, you should clarify the parameters of the crusher used, especially the requirements for the nature of the material. According to the requirements of the crusher, put in suitable materials. If it does not meet the production of the crusher Process requirements, such as too high temperature or too much moisture, can be processed accordingly to make the material meet or approach the requirements of the crusher as much as possible.
