Jaw Plate
High Manganese Steel Jaw Crusher Wear Parts
Solution Overview
Jaw plates are the primary wear consumables for jaw crushers in quarry, aggregate and mineral processing plants. They include fixed jaw plate and movable jaw plate, working together to squeeze and crush rock and ore inside the crushing chamber.
Made of high manganese steel alloy, jaw plates feature excellent impact toughness and wear resistance. When the crusher operates, movable jaw plate reciprocates to apply compressive force on raw materials. The tooth profile gradually wears down under continuous rock impact and abrasion, which reduces crushing capacity and product gradation.
We supply standard and custom jaw plates, including tooth plate, cheek plate and side liners. Custom casting patterns, tooth profiles and dimensions can be produced according to crusher model or original samples.
Widely used for lithium ore, gold, copper, iron ore, aggregate and sand production lines. We provide material selection advice, bulk export packaging and long-term wear parts supply contracts for crushing plants.
Core Types: Fixed Jaw Plate | Movable Jaw Plate | Cheek Plate | Crusher Side Liners
Jaw Plate Types & Tooth Profile
We offer multiple tooth designs for different feed size and finished aggregate requirements.
- Coarse Tooth Jaw Plate – For large feed rock, primary coarse crushing, big gap setting, high throughput.
- Fine Tooth Jaw Plate – For smaller feed size, produce finer crushed stone and aggregate products.
- Sharp Teeth / Wave Teeth – Optimized for hard rock, improve biting effect and reduce slippage inside crushing chamber.
- Cheek Plate / Side Liner – Protect side wall of jaw crusher frame from abrasion, matched with jaw plates as full wear part set.
All jaw plates adopt high manganese steel casting with professional heat treatment to gain work-hardening property. The surface becomes harder under continuous rock impact, extending service life in heavy crushing workload.
Casting & Quality Control Process
- Model Confirmation Confirm jaw crusher model, plate drawing or old sample, select suitable tooth profile and alloy grade.
- Pattern Making & Molding Build casting mould according to dimensions and tooth shape.
- High Manganese Steel Melting & Pouring Alloy smelting and casting to guarantee chemical composition.
- Heat Treatment & Machining Quenching and tempering for toughness, finish machining of mounting surfaces.
- Inspection & Export Packing Dimension check, hardness test, ultrasonic defect detection, packed for sea freight shipment.

FAQ
Q: Is jaw plate a crusher consumable?
A: Yes. Jaw plate is the main wear part for jaw crusher. Continuous rock impact will wear down the tooth profile, periodic replacement is required to keep crushing efficiency.
Q: What material is jaw plate?
A: Main material is high manganese steel Mn13 or Mn18. It gets work-hardened under impact force, ideal for hard rock primary crushing.
Q: What is the difference between fixed jaw and movable jaw plate?
A: Fixed jaw plate is stationary mounted on crusher frame. Movable jaw plate moves back and forth to squeeze stones. They work as a pair for crushing.
Q: Can you cast jaw plates according to my old samples?
A: Yes, we can manufacture custom jaw plates based on your physical samples or technical drawings.
Q: How long is jaw plate service life?
A: Service life depends on rock hardness and feed size. Typically ranges from 1–6 months under normal quarry working conditions.
