The Impact of Jaw Plate Material Selection on Crusher Performance
When it comes to selecting materials for jaw plates, the key to wear resistance lies in achieving a balanced relationship between hardness and toughness. ①If the material is too hard, the depth of material compression decreases, resulting in reduced deformation and weakening the short-range sliding-and-chiseling effect between particles. ②On the other hand, materials with excellent toughness can significantly enhance fracture resistance, effectively preventing brittle fractures during compression and impact, while also improving their ability to withstand fatigue-induced deformation and cracking. Duma Machinery—China's leading experts in jaw crusher spare parts—point out that these two performance characteristics often conflict with each other, making it a major technical challenge in the industry to achieve an optimal balance.
