Duma Machinery - Professional Manufacturer of Jaw Crusher Parts
As a core component in the mining and crushing industry, the quality of jaw crusher parts directly impacts the overall performance of the machine. Duma Machinery specializes in the production of various crusher spare parts, with a particular focus on manufacturing high-wear-resistant crusher jaw dies (jaw dies), providing reliable crushing solutions for customers worldwide.
Working Principle of the Jaw Crusher
Jaw crushers are widely used in the primary crushing process in industries such as mining, building materials, and infrastructure. The crushing action occurs between two high-manganese plates, regardless of whether they have "teeth" or not. These teeth are referred to as the jaw plates or jaw dies:
● Fixed Jaw Plate: Vertically installed on the front wall of the frame, forming the static working surface of the crushing chamber. It comes in two designs: one-piece and split, both of which are highly reliable.
● Movable Jaw Plate: Driven by an eccentric shaft, it connects with the toggle plate to form the dynamic crushing surface. The movable jaw comes in two designs: one-piece and split, and is made from high-manganese steel.
These two components create a wedge-shaped crushing chamber that achieves an efficient "large feed, small discharge" crushing mode. High-quality crusher jaw dies significantly improve the crushing ratio and extend the life of the equipment.
Advantages of One-Piece Jaw Dies Design：
● Faster jaw die replacement – reduces downtime
● Fewer parts – no need for a center wedge
● Easy to install – suitable for maintenance in limited spaces and mobile applications
Advantages of Two-Piece Jaw Dies Design：
● Longer expected service life (when replaced as recommended)
● Reduced waste rate and cost per ton
● Equipped with standard lifting tools for the crusher
● By rotating the jaw dies as recommended, a good bite angle can be achieved

FAQ
Q: What is a jaw die?
A: They use compressive force to break material between a stationary piece of steel (called a jaw die) and a moving piece of steel that together create a V-shaped cavity called the crushing chamber.
Q: Jaw plate bolts loosening or breaking problem
A: Loosening or breaking of jaw plate bolts may result from incorrect installation of jaw dies. To fix this issue, contact Qiming Casting for the proper jaw plates or reinstall the jaw dies.
Q: What is the chemical composition of the jaw plate?
A: In general, jaw plates are made of high manganese steel which is the dominant wear material. High manganese steel is also known as Hadfield manganese steel, a steel whose manganese content is very high and which possesses austenitic properties.
