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.

How do the moving and fixed jaw plates work together to crush materials?
The jaw crusher, a critical piece of equipment in the coarse crushing stage of material processing, is widely used in industries such as mining and construction. Its core working principle relies on the coordinated action of a moving jaw plate (also known as the movable jaw liner) and a fixed jaw plate (the stationary jaw liner), which crushes materials by squeezing them within a V-shaped crushing chamber formed by the two high-manganese steel jaw plates.
