Fixed and Moveable Jaw Plate
Jiangxi Duma Machinery Manufacturing Co., Ltd. is one of the most credible manufacturers and suppliers of fixed and moveable jaw plate in China. Welcome to buy discount fixed and moveable jaw plate in stock here and get quotation from our factory. We also accept customized orders.
Product Introduction
Fixed and moveable jaw plate, the fixed jaw plate and moveable jaw plate form the crushing chamber of a jaw crusher, taking the full impact and compressive load of the feed material. Because these two plates wear faster than almost any other component in the crusher, buyers typically keep a rotation of spares on hand rather than ordering reactively after a breakdown.
As a long-standing supplier of jaw crusher wear parts casting for global mining and aggregate operations, Duma Machinery produces these components as direct cast-and-machined replacements, manufactured in-house from raw material inspection through heat treatment and final dimensional checks. Every set is built to match the original installation geometry, so there is no on-site grinding or adjustment required before fitting.
Choosing the Right Alloy for Your Operation
The manganese grade you select for your fixed and moveable jaw plate has a direct effect on two things buyers care about most: cost per ton processed, and how long the plate lasts before it needs flipping or replacing.
A lower manganese content (around 13% Mn) keeps unit cost down and works well where the feed material is relatively soft and the crusher runs at moderate throughput, since the plate isn't being pushed to its hardness limit anyway.
Stepping up to roughly 18% Mn is where most general-purpose operations land, because it holds up well against harder feed (iron ore, general aggregate) without the cost premium of the highest grades.
For operations running highly abrasive rock at high tonnage, around 22% manganese with added chromium delivers the work-hardening performance needed to avoid frequent plate changes, and the higher upfront cost is usually offset by fewer replacement cycles and less downtime.
If your site runs an unusual ore profile, our engineering team can also formulate custom alloy ratios or add titanium carbide inserts for sites where standard manganese steel wears out faster than expected.

If your model isn't listed, our pattern library covers over 4,000 jaw crusher configurations, and we can also produce custom plates from drawings or worn sample plates through reverse engineering.
Sizing and Configuration
Jaw plates are supplied in matched pairs (fixed and moveable) sized to fit the chamber dimensions of your specific crusher model. Both flat and corrugated tooth profiles are available, and plates are designed with a symmetrical wear pattern so they can be flipped and reused once the active face reaches its wear limit, extending total service life before replacement. Because dimensions vary significantly by crusher size and model, please share your crusher brand and model number (or an original drawing/sample) so we can confirm exact specifications for your application.
Lead Time and Order Quantities
Jaw plates for common crusher models are kept in stock and typically ship within 7-10 days. Custom castings for less common models or special alloy specifications generally require 35-45 days for production. We accept trial orders starting from a small quantity per model, so buyers can verify fit and material performance before committing to bulk purchasing.

FAQ
Q: How do I know when the fixed and movable jaw plates need to be replaced?
A: Replacement is usually required when the tooth profile is significantly worn, output size becomes inconsistent, or the crusher capacity drops noticeably. Regular inspection of the wear surface is recommended to avoid unexpected downtime.
Q: Can jaw plates be rotated or reused after initial wear?
A: Yes, most jaw plates are designed with a reversible structure. Once one side reaches its wear limit, the plate can be flipped to use the opposite side, extending overall service life.
Q: Do different tooth profiles affect crushing performance?
A: Yes. Tooth profiles such as flat, corrugated, or quarry-style designs influence grip, throughput, and final product size. The selection depends on feed material hardness and required output size.
Q: What information is needed to confirm compatibility before ordering?
A: Typically, crusher model number, OEM part number, chamber profile, or an original drawing/sample is required to ensure correct fit and alignment with your machine.
Q: Can custom jaw plates be manufactured for non-standard or modified crushers?
A: Yes. Custom production is available based on drawings or worn samples. Reverse engineering can be used to replicate or improve existing designs for special applications.
