Duma Machinery specializes in producing high-quality wear parts for jaw crushers, providing reliable crushing solutions for industries such as mining, construction, and infrastructure. As an industry-leading manufacturer, we fully understand the critical role that
● Standard Jaw Plate: Made from 13% manganese + 2% chromium iron alloy
● Reinforced Jaw Plate: Made from 18% manganese + 2% chromium iron alloy
● Custom High-Performance Jaw Plate: Made from 21%-24% manganese + 2% chromium iron alloy
Through special heat treatment processes, the wear resistance of our jaw crusher main parts is significantly enhanced. Customer feedback shows that the service life of these parts is extended by 20-30% compared to regular products. All jaw plates are made from high manganese steel (Hadfield manganese steel), a material with an austenitic structure that combines excellent toughness and ductility, allowing it to continuously harden during use.
