Sandvik vertical shaft impact crusher has been widely used in mining, construction, metallurgy and other fields with its efficient crushing capacity and stable performance. However, as one of the core components of the crusher, the throwing head will inevitably wear out during long-term use, and this wear has a profound impact on the working efficiency of the crusher.As a key component directly involved in the crushing process of the vertical shaft impact crusher, the high-frequency impact and friction between its surface and the material are the main causes of wear. When the material enters the crushing chamber, the throwing head throws the material out through the centrifugal force generated by high-speed rotation, and the material is crushed in the process of hitting the impact plate or other materials. In this process, the surface of the throwing head is constantly impacted and abraded by the material, and gradually wears out.As the wear of the throwing head increases, its surface shape and size will change, which directly affects the working efficiency of the crusher. First, the surface of the throwing head becomes smooth after wear, and the friction coefficient between it and the material decreases, resulting in a decrease in the kinetic energy obtained by the material when it is thrown out. This means that when the material hits the impact plate or other materials, the crushing effect will be worse, and more throws and longer time are required to achieve the ideal crushing particle size. This not only reduces the working efficiency of the crusher, but also increases energy consumption.Secondly, the wear of the throwing head will also cause changes in the flow field inside the crusher. As the shape of the throwing head changes, the movement trajectory of the material in the crushing chamber will also change, resulting in uneven material distribution, with too much material accumulation in some areas and scarce material in some areas. This uneven material distribution will further reduce the crushing efficiency, because too much material accumulation will increase the load on the throwing head, while areas with scarce material cannot fully utilize the crushing capacity of the throwing head.In addition, severe wear of the throwing head may also cause unbalanced operation of the crusher. When the surface of the throwing head is unevenly worn, it will generate unbalanced forces during rotation, which will not only increase the load on the bearings and other rotating parts, but also cause vibration and noise, further reducing the working efficiency and stability of the crusher.In order to reduce the impact of throwing head wear on the working efficiency of Sandvik vertical shaft impact crusher, users need to take a series of measures. First of all, choosing high-quality throwing head materials is the key. Wear-resistant materials can extend the service life of the throwing head and reduce the impact of wear on work efficiency. Secondly, regular inspection and maintenance of the throwing head is also essential. By timely discovering and replacing severely worn throwing heads, the negative impact on the working efficiency of the crusher can be avoided. In addition, reasonable adjustment of the crusher's working parameters, such as speed, feed particle size, etc., can also reduce the wear of the throwing head to a certain extent and improve work efficiency.In summary, the wear of the throwing head has a significant impact on the working efficiency of Sandvik vertical shaft impact crusher. Users need to pay attention to the wear problem of the throwing head and take effective measures to reduce its negative impact on the working efficiency of the crusher to ensure the stable operation and efficient operation of the crusher.
