Publish Time: 2025-02-03
As a leader in modern crushing technology, Sandvik vertical shaft impact crusher throwing head has been widely used in many industrial fields due to its high efficiency, energy saving and environmental protection. As a key component of Sandvik vertical shaft impact crusher throwing head, the design, manufacturing and performance of the throwing head directly affect the crushing efficiency and service life of the whole machine.1. Design principle of throwing headThe throwing head design of Sandvik vertical shaft impact crusher throwing head is based on the principle that the high-speed rotating impeller throws the material at high speed for impact crushing. The throwing head is usually located at the edge of the impeller, and the centrifugal force generated by high-speed rotation throws the material to the surrounding guard plate or other materials of the crushing chamber to achieve the purpose of crushing. During the design process, factors such as the hardness, humidity, particle size of the material and the structure of the crushing chamber need to be fully considered to ensure that the throwing head can work efficiently and stably.2. Material selection of throwing headThe working environment of the throwing head is extremely harsh, and it needs to withstand complex conditions such as the centrifugal force generated by high-speed rotation, the impact wear of the material, and high temperature and high pressure. Therefore, the material selection of the throwing head is crucial. At present, common throwing head materials include high manganese steel, wear-resistant alloy steel, ceramics, etc. Among them, high manganese steel has good impact toughness and wear resistance, and is suitable for processing dry materials; while wear-resistant alloy steel has higher hardness and wear resistance, and is suitable for processing wet materials or materials with higher hardness. Ceramic materials are the first choice for processing extremely hard materials due to their extremely high hardness and wear resistance.3. Manufacturing process of throwing headThe manufacturing process of throwing head also affects its performance and service life. Common manufacturing processes include casting, forging, welding, etc. The casting process is suitable for producing throwing heads with complex shapes and large sizes; the forging process can improve the density and strength of the throwing head; the welding process is suitable for combining parts of different materials or different shapes to form a throwing head with a complex structure. During the manufacturing process, the heat treatment process also needs to be strictly controlled to ensure that the hardness and toughness of the throwing head are optimally balanced.In summary, the core technologies of Sandvik vertical shaft impact crusher throwing head involve design principles, material selection, manufacturing process, optimization and innovation, maintenance and care, etc. Only by fully understanding and mastering these core technologies can we ensure the efficient, stable and long-term operation of Sandvik vertical shaft impact crusher throwing head.
