Zhejiang MP Mining Equipment Corp., Ltd. is one of the most credible manufacturers and suppliers of High manganese steel Jaw Plate in China. Welcome to buy discount High manganese steel Jaw Plate in stock here and get quotation from our factory. We also accept customized orders.
The High Manganese Steel Jaw Plate is the core wear part of a jaw crusher. It includes the fixed jaw plate and movable jaw plate, which directly participate in the crushing process by applying compression and shear force to materials inside the crushing chamber.
Unlike toggle plates, jaw plates are the main crushing components. Their profile, material quality, and manufacturing precision directly determine:
MP Mining specializes in manufacturing OEM-compatible high manganese steel jaw plates for global jaw crusher brands, providing reliable wear solutions for mining, quarrying, and recycling industries.

By Structural Design
Used in most modern jaw crushers. Provides higher rigidity and simpler installation.
Designed for large crushers to reduce replacement cost by changing only worn sections.
By Tooth Profile
Different tooth profiles are selected according to material hardness and feed size
Uneven Wear
Caused by incorrect feeding position or chamber mismatch..
Excessive Impact Load
Oversized feed material leads to localized impact concentration.
Improper Material Selection
Wrong manganese grade reduces service life.
Incorrect Installation
Loose bolts or poor seating contact increase vibration and breakage.
Poor Maintenance
Delayed replacement causes secondary damage to crusher structure.

Environmental Management System CertificateQ: What is the function of a jaw plate?
A: Jaw plates are the main crushing surfaces in a jaw crusher. They directly compress and fracture material while defining chamber geometry and crushing efficiency.
Q: Why choose high manganese steel?
A: High manganese steel provides excellent work-hardening ability, impact resistance, and crack prevention, making it ideal for heavy crushing environments.
Q: How long is jaw plate service life?
A: Service life depends on material hardness, feeding condition, and plate grade. MP Mining jaw plates typically last 20–40% longer than standard market products.
Q: What is your minimum order quantity (MOQ)?
A: We accept small trial orders for quality validation , allowing you to verify our material's work-hardening performance before bulk commitment.
