In the face of materials of different hardness and characteristics, metso vertical shaft impact crusher throwing head adjusts its performance to cope with them in the following ways:1. Adjust the material and structure of the throwing headMaterial selection: For materials with higher hardness, the throwing head needs to use materials with higher wear resistance and toughness, such as high manganese steel, alloy steel, etc., to reduce wear and damage. For corrosive materials, the throwing head needs to use corrosion-resistant materials, such as stainless steel or special alloys, to prevent performance degradation caused by corrosion.Structural design: According to the hardness and characteristics of the material, adjust the shape, thickness and weight of the throwing head to optimize its crushing effect and wear resistance. Design a reasonable throwing head angle and impact surface to ensure that the material is fully impacted and crushed in the crushing chamber.2. Adjust the motion parameters of the throwing headRotation speed: By adjusting the rotation speed of the throwing head, the frequency and strength of its impact on the material can be changed to adapt to materials of different hardness and characteristics. Generally speaking, for materials with higher hardness, the rotation speed of the throwing head needs to be increased to increase the impact force; for softer materials, the rotation speed can be reduced to reduce wear.Impact angle: Adjusting the impact angle of the throwing head can change the force direction and size of the material in the crushing chamber, thereby affecting the crushing effect and particle size distribution. By optimizing the impact angle, the material can be crushed and ground more evenly in the crushing chamber.3. Adjust the overall parameters of the crusherFeeding amount: According to the hardness and characteristics of the material, adjust the feeding amount to control the workload of the crusher. For materials with higher hardness, the feeding amount needs to be appropriately reduced to avoid overload; for softer materials, the feeding amount can be appropriately increased to improve production efficiency.Discharge port size: By adjusting the size of the discharge port, the particle size distribution of the material after crushing can be controlled. For materials that need fine crushing, the discharge port size can be reduced to obtain finer particle size; for materials that need coarse crushing, the discharge port size can be increased.4. Use intelligent control systemModern impact crushers are usually equipped with intelligent control systems, which can automatically adjust the motion parameters of the throwing head and the overall parameters of the crusher according to the hardness and characteristics of the material. By real-time monitoring of information such as material flow, crushing effect and equipment operation status, the intelligent control system can automatically adjust the parameters such as the rotation speed, impact angle, feed amount and discharge port size of the throwing head to achieve the best crushing effect and energy consumption ratio.In the face of materials with different hardness and characteristics, metso vertical shaft impact crusher throwing head responds by adjusting the material and structure, motion parameters and the overall parameters of the crusher. At the same time, the use of intelligent control systems can further improve the adaptability and production efficiency of the crusher.
