 t is normal for the sand making machine to block material, but if it is blocked frequently, it will affect the progress of the entire production line. Therefore, how to deal with the material blocking problem of the sand making machine, the technical engineer of Jiaozuo Zhongxin Heavy Industry summarized 8 situations.

    1. The material has a large water content
    If the material has too much moisture, it may stick to the sand making machine. An effective solution is to pre-heat the material at the inlet.
    2. The material is too hard or the particle size is too large
    When the material is too hard or the crushed material is too large and exceeds the crushing range of the sand making machine, it will also cause clogging. The size of the crushed material should not exceed the specified range and hardness.
    3. Feeding speed is too fast
    The feeding speed and the processing speed are not well matched, the feeding is fast, the crushing is slow, the discharge is too late, the equipment is prone to overload work, which will cause the occurrence of material blockage, so when feeding the sand making machine, it must be ensured The uniformity and continuity of feeding reduces the problem of equipment blockage.
    4. Improper tightness of the triangle belt
    The production process of the sand making machine relies on the V-belt to transmit the power to the sheave wheel, and then crush the stone. When the triangular drive belt is loose, it will cause slipping, and it will rotate with the sheave instead of driving the sheave. The material cannot be subjected to normal crushing force, and cannot be crushed in the crushing cavity, resulting in material blockage.
    5. Improper adjustment of the discharge opening
    In the production process of the crusher, if the discharge speed of the material is too slow, it will cause the subsequent crushed materials to accumulate in the discharge port and the crushing cavity, causing discharging obstacles.
    6. Coordination of production line equipment
    For example, when the conveying capacity of the conveyor exceeds the crushing capacity, when the conveying capacity of the conveyor does not match the crushing capacity of the crusher, the materials behind the crusher will quickly enter the crusher without being crushed, which will cause blockage when the crushing is not timely.
    7. Improper manual operation
    This is a common cause of material blocking in sand making machines. The operator of the sand making machine must be systematically trained and be familiar with the equipment before taking up the job, otherwise it will not only cause the low production capacity of the equipment, but also cause damage to the equipment over time.
    8. The problem of the equipment itself
    Incorrect selection of the sand making machine model will also cause blockages in the production process. Therefore, when purchasing, communicate with the technicians, inform the technicians of the material to be crushed, the size of the crush, etc., and select the appropriate machine model.
