The main working parts of hammer crusher are rotors with hammers (also known as hammers). The rotor consists of a main shaft, a disc, a pin shaft and a hammer. The motor drives the rotor to rotate at high speed in the crushing chamber. Hammer head is the main wearable part. The quality of hammer head directly affects the crushing efficiency of crusher. Working Principle: The main working parts of hammer crusher are rotors with hammers (also known as hammers). The rotor consists of a main shaft, a disc, a pin shaft and a hammer. The motor drives the rotor to rotate at high speed in the crushing chamber. Hammer head is the main wearable part. The quality of hammer head directly affects the crushing efficiency of crusher. During the working period of hammer head, besides being impacted, it is also impacted by material. In this way, the working face of hammer head will be damaged and the surface shape will change if it is used repeatedly for a long time. At present, the hammer head of hammer crusher in China is mostly made of high manganese steel. Material is crushed by the impact, impact, shearing and abrasion of a high-speed hammer in the feeding machine from the upper feed port. In the lower part of the rotor, the sieve plate and the size of crushed material smaller than the sieve hole are discharged through the sieve plate. The coarse particles larger than the sieve hole size are blocked on the sieve plate and continue to be attacked and ground by the hammer. Finally, the sieve plate is discharged out of the machine. High wear-resisting double-alloy compound hammer head has a service life of more than five times that of original products such as manganese steel and rails, and its crushing efficiency has been increased by more than 30%. The wear-resisting double-alloy compound hammer head is developed by Zhangjiagang Hengxinda Company and is the latest technology in the industry. Its main feature is to use two kinds of alloy liquid to compound, and the casting process is centrifugal pressure casting, avoiding inlaying. It is easy to fall off and wear-resistant, and has been used in hundreds of cement and mining enterprises, and is well received by customers. Hammer head part is made of high hardness and high wear resistance alloy steel with hardness up to HRC62-65. Hammer handle part is made of high toughness manganese steel. Because the two alloys are metallurgical liquid-liquid composite, there is no need to worry about falling off. It solves the shortcomings of single alloy material, such as high hardness, easy breaking and good toughness and wear resistance. Therefore, the service life and working efficiency of the hammer head are greatly improved. High wear-resistant dual-alloy composite hammers are widely used in coke, coal, coal gangue, metallurgy, glass, mining ore, cement plant limestone, clinker, brick factory foliate and other crushing industries! Especially the large single-stage hammer crusher shows its superiority. Hammer features: new casting process, with wear-resistant, impact-resistant judgment method: Hammer head of hammer crusher has not been abraded at the surface and angular position when it was just put into production, the hammer head mainly bears impact force, and materials impact the hammer surface with positive force, resulting in hammer head deformation and concave-convex, but if the hammer head appears abrasion, the force surface of its surface will appear some points. Solution: The reverse force on the hammer surface will impact the hammer, while the tangential force will exert cutting force on the hammer. The impact force of hammer crusher in crushing material is reduced directly, the production efficiency is reduced and the crushing time is increased. Therefore, when the force of the hammer head of the hammer crusher shifts and the wear of the hammer head changes, the service life of the hammer head will end and the hammer head will fail. Change configuration: 1. Calculate the balance method of hammer head of crusher 2. Selection skill of hammer head of crusher on-site rotation method: hammer head of hammer crusher is the main component affecting the use of crusher. ｓｅｌｅｃｔ high-quality hammer head of hammer crusher through the following five directions: 1. Look at the material of hammer head of hammer crusher 2. Look at the structure design of hammer head of hammer crusher 3. Look at hammer crusher Manufacturing Technology of Hammer Head IV.
