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.
