Product Core Introduction: Professional, Reliable, Customizable
Aluminum oxide ceramic jaw plate is a high-performance composite wear-resistant material designed to address the extreme wear challenges faced by jaw crushers when crushing high hardness and highly abrasive materials such as iron ore, granite, quartz, basalt, etc.
Product Structure and Materials
Ceramic layer: Made of high-purity aluminum oxide (Al ₂ O3) ceramics with a purity of 92% -95% or higher, sintered at 1700 ℃. With extremely high hardness (HRA ≥ 85, Mohs hardness level 9) and excellent wear resistance, it is the core barrier to resist material wear.
Buffer layer: a special high elasticity rubber layer located between the ceramic and steel plate. It can effectively absorb the impact energy generated during the crushing process, prevent the ceramic layer from shattering due to impact, and enhance the overall impact resistance.
Substrate layer: High quality steel plate (such as Q235), providing structural support and installation interfaces, making it easy to fix on the crusher body through bolts or welding.

Application scenarios and problem solutions
Application problems solved
Rapid wear of the E Po moving fixed plate: Traditional manganese steel lining plates wear extremely quickly when crushing high hardness ores, and frequent replacement leads to high costs and long downtime. The ultra-high wear resistance of ceramic lining completely solves this pain point.
High impact may cause damage to the lining plate: During the crushing process, the impact of large pieces of ore may cause deformation or cracking of the lining plate. The ceramic lining plate with composite structure effectively buffers the impact through a rubber layer, preventing ceramic fragmentation.
Material contamination issue: Iron filings generated by the wear of metal lining plates can contaminate the materials. Ceramic lining plate has stable chemical properties, no iron pollution, and ensures product quality.
High energy consumption of equipment: The heavy metal lining plate increases the operating load of the equipment. Lightweight ceramic lining helps reduce energy consumption.
Material adhesion blockage: The rough metal surface is prone to material adhesion, which affects the crushing efficiency. Smooth ceramic surface reduces adhesion and keeps the cavity unobstructed.
