Duma Machinery – A Professional Manufacturer of Jaw Crusher Parts
As the core equipment in the mining crushing industry, the quality of jaw crusher parts directly affects the performance of the entire machine. Duma Machinery specializes in manufacturing various crusher spare parts and is particularly adept at producing highly wear-resistant crushers. E-board (Including the moving jaw plate and fixed jaw plate), providing reliable crushing solutions for customers worldwide.
Working Principle of Jaw Crushers
Jaw crushers are widely used in primary crushing operations in fields such as mining, construction materials, and infrastructure development. The crushing action takes place between two manganese steel jaw plates; whether or not these plates have “teeth,” these teeth are referred to as jaw plates.
● Fixed jaw plate: Mounted vertically on the front wall of the frame, it forms the static working surface of the crushing chamber. It comes in two designs: monolithic and modular; both designs are highly reliable.
● Moving jaw plate: Driven by an eccentric shaft, it is connected to the toggle plate to form a dynamic crushing surface. The moving jaw comes in two designs—monolithic and split—and both are made of high-manganese steel.
The wedge-shaped crushing chamber formed by the two components achieves an efficient crushing mode characterized by "large feed and small discharge," while the high-quality crusher... E-board It can significantly improve the crushing ratio and equipment lifespan.
Advantages of an integrated jaw plate design
• Faster jaw plate replacement—reducing downtime
• Fewer parts—no center wedge required
• Easy to install – ideal for applications with limited maintenance space and mobile environments.
Advantages of the two-piece jaw plate design
• Expected longer service life (when replaced as recommended)
• Reduce defect rates and per-ton costs
• The crusher is equipped with standard lifting tools.
• Rotate as recommended E-board , which can achieve a good occlusal angle.
Jaw Crusher Parts – Jaw Plate Type
Jaw plates used in jaw crushers come in various types, each with its own specific application. Here are some common types of jaw plates:
Straight jaw plate: This is a basic jaw plate type used for general-purpose crushing. They feature a simple design and are typically made from manganese steel, which is renowned for its toughness and durability.
Corrugated jaw plate: These jaw plates feature a corrugated surface that helps grip the crushed material and prevents it from slipping. This design is particularly effective when crushing hard or abrasive materials.
Tooth profile Jaw plate ： These jaw plates feature teeth or ridges on their surfaces, which help to grip and crush materials. They are particularly well-suited for crushing hard and brittle materials, such as concrete or rock.
