Optimizing the Selection of Fixed and Moving Cone Liners for Limestone Crushing Efficiency
Professional research shows that equipping a crushing system with high-quality gyratory crusher mantle liners can significantly enhance equipment performance. The design precision of the moving cone liner and the wear-resistant properties of the stationary cone liner directly influence crushing efficiency. In addition to raw material characteristics, the degree of wear on both the moving and stationary cone liners is closely tied to the proper selection of these critical components.

Optimization Design and Maintenance Key Points for Wear Parts of Jaw Crushers
The core working components of the jaw crusher consist of a moving jaw plate and a stationary jaw plate, which endure tremendous impact forces and material friction during the crushing process, making them highly susceptible to wear. To enhance the equipment's durability, Duma Machinery installs wear-resistant liners (also known as crushing plates) on the surfaces of both the moving and stationary jaw plates, effectively extending the machine's service life.
