The counter-type ssand making machine is a common crushing equipment used in mining, chemical, metallurgy, building materials, electric power and other industries, and the hammer head is the main wearable part of the equipment. Its good quality and long service life directly affect the crushing machine. effectiveness. During the work, the hammer head is subjected to the double action of impact and material impact. After repeated use for a long time, the working surface of the hammer head is damaged, and the surface shape changes, so frequent replacement is required. 1. Structural design and product quality of the hammer head The structural design and geometry of the hammerhead have a great influence on the mechanical properties after heat treatment and the internal metallographic structure. In particular, the hammer head with a large thickness has a more prominent influence. By analyzing the fracture failure modes of hammers of different materials, it is known that the main cause of the hammer fracture is that there are different degrees of defects inside or on the surface. Due to the presence of defects, most of the hammers are broken at the beginning of use. Therefore, in the production of hammers, reasonable casting and heat treatment processes must be established. 2. Technical parameters of the counter-type sand making machine The technical parameters of the counter-type sand making plant also affect the service life of the hammer head, the main one being the power and speed of the rotor. They are not only related to the production capacity of the crusher, but also to the degree of impact hardening of the hammer. The hammerhead has a good degree of impact hardening and its service life is prolonged. 3. Blockiness and hardness of the broken material The greater the material mass, the higher the toughness requirement, and the higher the material hardness, the higher the hardness requirement of the hammer material. The specific type of crusher should adopt the appropriate feed size, which will extend the service life of the hammer to a certain extent. 4. Adjustment of internal clearance of counter-type sand making machine ZENITH heavy work is a professional crusher equipment manufacturer. The main products are jaw crusher, impact crusher, impact crusher, hammer crusher, counter-type sand making machine, sand making machine, beneficiation equipment, etc. Customers provide more efficient and high-quality crushing equipment products and sincere and perfect services, and make greater contributions to the development of crusher equipment industry in China.
