Hammer crusher failure and solution

Hammer crushers are often subjected to high torque and vibration during operation, which can lead to failures in the transmission system. Common issues include wear in the bearing chamber, bearing positions, pulley hubs, shafts, and keyways. These problems can significantly affect the performance and lifespan of the equipment.

Traditionally, maintenance has relied on methods like welding or brush plating. However, both approaches have limitations. Welding introduces thermal stress that may damage the material, leading to warping or breaking of parts. Brush plating, on the other hand, is limited by coating thickness and is prone to peeling. Moreover, these methods involve repairing metal with metal, resulting in a "hard-to-hard" contact that doesn’t solve the root cause of wear, making reoccurrence likely under continuous stress.

In many developed countries, such as the U.S. and Europe, a more advanced solution is widely used: polymer composite materials. These materials offer strong adhesion, excellent mechanical properties, and compressive strength, allowing for on-site repairs without disassembly or machining. Unlike traditional methods, they don’t introduce thermal stress and allow for flexible repair thickness. Additionally, polymer composites are not rigid like metal, which helps absorb shocks and vibrations, reducing the risk of future wear. This technology extends component life, minimizes downtime, and delivers significant cost savings and long-term value for businesses.
