The Jaw Crusher Jaw Plate is the core working part of a jaw crusher, fitted to the fixed and movable jaws inside the crushing chamber. It is primarily crafted from high-manganese steel or heat-treated wear-resistant alloy steel, boasting high hardness, superior wear resistance and reliable impact toughness. It endures intense extrusion, repeated impact and severe abrasion when crushing hard ores, rocks and other raw materials in tough working environments, and its performance directly impacts the jaw crusher’s operational efficiency, product particle size quality and service life.
