China Factory Suppliers Jaw Crusher Plate - Durable High Manganese Steel for Mining and Energy Industries

The jaw plate of our jaw crusher, produced by a leading factory in China, consists of two main parts: the fixed jaw plate and the movable jaw plate, both made from high-manganese steel castings. During operation, the movable jaw plate performs a compound swing motion, creating a crushing angle with the fixed jaw plate to effectively compress stones. Due to the demanding nature of this operation, jaw plates experience significant wear and will need replacement periodically. To enhance their durability, the design is typically symmetrical, allowing for easy reversal of the plates when one side wears out. As a key contact surface in stone crushing, our movable jaw plate safeguards the movable jaw itself. Trust in our expertise as reliable suppliers in the industry for robust and efficient jaw plates that meet all your crushing needs

    Methods to extend the service life of the jaw plate

    Negative Suspension

    The positive suspension of the eccentric shaft device of the traditional compound swing jaw crusher is changed to negative suspension, improving the crusher characteristics and extending the jaw plate life by 50%.

    Upward Inclined Thrust Plate

    Changing the thrust plate to an upward inclined type creates a downward component in the crushing stroke. This facilitates material crushing, reduces blockage, improves wear conditions, and enhances processing capacity.

    Double Movable Jaw Design

    Replacing the single movable jaw with a double movable jaw brings longitudinal relative movement between the two jaws close to zero, eliminating wear from mechanical motion characteristics.

    Curved Movable Jaw Shape

    Changing flat movable jaws to curved ones reduces excessive crushing from poor material discharge. The ideal jaw surface shape is designed straight on the top and curved on the bottom.

    Frequently Asked Questions

    How can changing to negative suspension extend the jaw plate life?

    By changing the positive suspension of the traditional compound swing jaw crusher's eccentric shaft device to negative suspension, the crusher's motion characteristics are improved, which can extend the jaw plate's service life by 50%.

    What are the benefits of an upward inclined thrust plate?

    An upward inclined thrust plate creates a downward component in the crushing stroke of the movable jaw. This promotes the downward movement of materials, reduces blockages, improves wear conditions, and enhances the crusher's overall processing capacity.

    Why is a double movable jaw design better than a single movable jaw?

    A double movable jaw minimizes the longitudinal relative movement between the two jaws to nearly zero. This mechanical improvement eliminates longitudinal relative movement between the jaw plates, significantly reducing wear.

    How does a curved movable jaw improve jaw crusher performance?

    Changing from a flat to a curved movable jaw (ideally straight on top and curved on the bottom) reduces excessive material crushing caused by poor discharge at the outlet, preventing severe wear on the movable jaw.

    What testing procedures are included in your quality assurance system?

    Our quality assurance testing system includes incoming raw material testing, surface and core hardness testing, chemical composition testing, impact testing, and other customized tests required by the customer.

    What materials are used for your crusher wear parts?

    We manufacture high-quality, long-life wear parts using high Mn (Manganese), Cr (Chromium), Mo (Molybdenum), and alloy steel. These parts are compatible with cone, jaw, impact, hammer, and roller crushers, and can be fully customized.
