How to prolong the service life of the hammer head of the crusher
Focus on the problem of improving the wear resistance of the hammer head of the crusher and prolonging the service life. The factors that determine the service life of a crusher hammer are as follows:
1. Whether the work is reliable. During the impact between the hammer head of the crusher and the material, the hammer head is not allowed to fly away from the rotor, or other mechanical failures are caused due to the poor fastening of the hammer head, so the fixing of the hammer head is a problem worthy of attention. Otherwise, there is no “lifetime” at all.
2. Whether the loading and unloading of the hammer is convenient, especially the reproduction phenomenon, after working for a period of time, the various parts of the machine must not be carried out in the ideal condition, such as eccentricity, partial wear, etc., need to be adjusted in time. Quick loading and unloading is a very important indicator.
3. Whether the metal utilization rate of the hammer is reasonable. Because the abrasion of the hammer head is inevitable, a hammer head with a certain weight makes the unusable mass small, that is, how to choose the shape and space size of the hammer head is a problem worthy of consideration.
4. To reduce unnecessary wear and increase the service life of the hammer head, to make full use of the energy of the rotor and increase the crushing ratio, it is necessary to study a larger crushing force, which also has great theoretical value.
5. The timely and reasonable deployment of hammers is very important. The crusher runs unstable and vibrates greatly during use. The main reason is that the original balance of the hammer is destroyed after the hammer is worn, and the scientific method is not used for reasonable deployment.
6. The material of the hammer head is the core factor to solve the hammer head’s wear resistance and service life. Nowadays, it is widely used and has withstood the test of practice. For example, there are modified high-manganese steel hammers and hammers, and medium-carbon multi-alloy steel hammers.
