The throwing head of Sandvik vertical shaft impact crusher is one of the core components of the equipment. Its function directly affects the crushing efficiency, finished product quality and equipment stability. Its main function is to throw the material to the impact plate or material layer in the crushing chamber through high-speed rotation, and use the impact force to achieve material crushing and shaping.The throwing head is usually installed on the vertical shaft of the crusher and driven by a motor to rotate at high speed. After the material enters the crushing chamber from the feed inlet, it falls on the rotating throwing head and is accelerated and thrown outward under the action of centrifugal force. This process not only gives the material extremely high kinetic energy, but also causes it to collide with the liner or other materials in the crushing chamber, thereby achieving crushing and shaping. Because the throwing head has an extremely high rotation speed, which can usually reach tens of meters per second or even higher, it can effectively crush medium and high hardness rocks, ores and other mineral raw materials.The design of the throwing head directly affects the performance of the crusher. Sandvik uses high-strength alloy materials to manufacture the throwing head to improve its wear resistance and impact resistance, thereby extending its service life. At the same time, the geometry and weight distribution of the throwing head are precisely calculated to ensure dynamic balance at high speeds, reduce equipment vibration and bearing load, and improve operational stability. In addition, the structural design of the throwing head also affects the material projection angle and speed, which in turn affects the crushing efficiency and the particle shape of the finished product.The role of the throwing head is particularly critical in the sand and aggregate production process. It not only determines the processing capacity of the crusher, but also affects the particle shape, gradation and powder content of the final product. A high-quality throwing head can form a good "stone-on-stone" or "stone-on-iron" crushing pattern of the material in the crushing chamber, thereby reducing needle-like particles and increasing the proportion of cubic particles, making the finished product more in line with the standards of industries such as construction, concrete and asphalt mixtures.In addition, the maintenance and replacement of the throwing head is also an important factor affecting the long-term operating cost of the equipment. Sandvik throwing heads adopt a modular design, which is easy to replace quickly and reduces downtime. At the same time, by regularly checking the wear and tear and adjusting the speed and feeding method according to the working conditions, the service life and crushing effect of the throwing head can be further optimized.In summary, the core function of Sandvik vertical shaft impact crusher throwing head is to achieve efficient crushing and shaping through high-speed rotation and precise ejection of materials, while ensuring stable operation and long-term durability of the equipment. Its design, materials and maintenance strategy jointly determine the overall performance of the crusher, and it is an indispensable key component in sand making and aggregate production.
