Zhejiang MP Mining Equipment Corp., Ltd. is one of the most credible manufacturers and suppliers of replacement crusher jaws in China. Welcome to buy discount replacement crusher jaws in stock here and get quotation from our factory. We also accept customized orders.
The replacement crusher jaws produced by MP Mining Machinery have recently been shipped from China to Canada. Jaw crushers are critical machines in heavy-duty crushing operations, and the quality of their wear parts directly determines production efficiency and maintenance costs. MP Mining's replacement crusher jaws-including fixed and swing jaw plates-are designed to withstand extreme impact and abrasion while maintaining precise fit with the crusher body.
Crusher Jaw Plate Casting
Because crusher jaw plate casting are constructed of super high manganese steel, they last 50–100% longer than plates made of conventional high manganese steel. Under a variety of load scenarios, each type of jaw crusher in the PE series is tested for shock, stress, strain, heat loading, deformation, vibration, and noise.
Jaw Fixed Plate and Swing Plate
Jaw fixed plate and swing plate is an important part in the jaw crusher equipment, and its service life directly affects the whole jaw crusher equipment. Therefore, you must consider the hardness and toughness of the jaw plate when you want to choose a correct one.
Jaw Swing Plate
The jaw crusher is a commonly used crushing equipment in the mining industry. It consists of a fixed plate, a movable plate, and a jaw swing plate, all made from durable materials to withstand the demanding conditions of the crushing process.
Several different types of Jaw Plates are available, each suited for various applications and crushing requirements. to explain how different shapes of jaw plates correspond to the application sites and the materials being crushed.
Standard (XT710) and Super Grip (XT710) : Ideal for gravel and non-abrasive rock crushing, these types offer balanced power requirements and tooth spacing for fines removal, resulting in less slabby product. However, they have a reduced lifetime in abrasive applications.
Superteeth (XT710): Suited for general use in gravel and blasted rock, these plates offer increased tooth contact surface area, more wear-resistant Mn-steel, and balanced power requirements, resulting in less slabby product.
Quarry (XT710, MX): Suitable for abrasive or blasted rock, these jaw plates feature a flat tooth profile for extended lifetime, more wearable Mn-steel than standard jaws, and higher stresses and power requirements. Fines removal is crucial, but they may increase slabby product.
Quarry Thick (XT710, MX): These jaw plates are excellent for abrasive and/or blasted rock, featuring a 40mm thicker fixed jaw die for a longer lifetime, a flat tooth profile, more wearable Mn-steel, and higher stresses and power requirements. Fines removal is vital, but they may increase slabby product.
Quarry + Super Grip (XT710): Designed for blasted rock, difficult natural rock, and slippery rock, these plates have a sharp tooth profile for a good grip on the rock, balanced power requirements, ideal tooth spacing for fines removal, and less slabby product.
Quarry Thick + Super Grip (XT710): Similar to the Quarry + Super Grip type but with a thicker fixed jaw die for longer lifetime and balanced power requirements, these plates are suitable for challenging rock conditions.
Anti-Slab (XT710, MX): These jaw plates have an uneven tooth height to reduce slabs in the feed material, resulting in less slabby product.
Coarse Corrugated Jaws: Offering improved material flow, better wear life, enhanced product quality, and incread production compared to regular jaw plates. These jaws are suitable for various applications.
Each jaw plate is precision-cast and heat-treated to achieve optimal hardness and toughness, ensuring a balance between wear resistance and structural strength. Our products undergo strict quality inspections, including hardness testing, dimensional checks, and surface defect scans, guaranteeing OEM-level compatibility with popular crusher models.
By upgrading to MP Mining Machinery replacement jaws, operators can extend wear part service life by up to 30%, reduce unplanned downtime, and achieve consistent, high-quality output. With customized solutions available for different rock types-such as granite, limestone, and iron ore-our jaw plates deliver reliable performance in even the toughest applications.

Q: What bearing is used in jaw crusher?
A: Jaw crushers typically utilize spherical roller bearings, chosen for their ability to manage high radial loads and the presence of misalignment. Spherical roller bearings self-align and thus better compensate for shaft deflections and seat misalignment.
Q: What is the jaw plate of a crusher made of?
A: Modern jaw crushers may have a main frame of welded mild steel plate. The jaws are usually constructed from cast steel and fitted with replaceable liners, made from manganese steel, or "Ni-hard," a Ni-Cr alloyed cast iron.
Q: When to choose high manganese steel jaw plate?
A: For large jaw crushers, the crushed material is huge-block, which forces the jaw plate to accept strong impact and wear. For that situation, the high manganese steel can give full play to the advantages of good toughness and hardness.
Q: Why it is most suitable to use medium manganese steel jaw plate at this time?
A: If you need to deal with materials with high hardness such as granite, quartz stone, concrete, etc., the medium manganese steel is the most suitable because of its strong hardening ability. Besides, it has a self-protection mechanism when crushing high hardness materials, which can greatly reduce the wear rate.
Q: When to choose medium-carbon-low-alloy cast steel jaw plates?
A: Medium and small sized jaw crushers usually bear a low impact load, so under such conditions, medium-carbon-low-alloy steel materials are more suitable. Not only can the disadvantages of high manganese steel difficult to reach the application hardness be avoid, but it also bring good technical and economic benefits.
