The movable jaw plate of the crusher is the core wear-resistant component of the jaw crusher, which directly participates in the extrusion and crushing process of the material. Its structure is usually designed as a plate with teeth patterns. The material is mostly high manganese steel (Mn13-Mn18) or chrome-molybdenum alloy steel. The surface hardness reaches HB200 or above through heat treatment process, which can not only withstand periodic impact loads, but also effectively resist material wear. The teeth shape arrangement of the movable jaw plate has been optimized by fluid mechanics. Common wave-shaped or trapezoidal teeth designs can enhance the bite and crushing effect of the material while reducing energy consumption. Modern movable jaw plates generally adopt modular design, and the teeth tips with severe wear can be replaced separately, which can reduce the maintenance cost by 30%-50% compared with the integral structure. During installation, it is necessary to keep precise gap matching with the fixed jaw plate. If it is too large, the crushing efficiency will be reduced, and if it is too small, it will easily cause blockage. According to different material characteristics, the movable jaw plate can choose surface welding hard alloy, composite ceramic liner and other strengthening solutions. In special working conditions such as construction waste treatment, a hydraulic adjustment device will also be set on the back of the movable jaw plate to achieve overload protection and rapid gap adjustment. Reasonable selection of movable jaw plate can increase the crusher's production capacity by 15%-20%. Its lifespan is usually calculated based on the processing volume, and can reach 80,000-120,000 tons under normal limestone conditions.
