颚板

颚板是安装在初级颚式破碎机固定颚和活动颚上的关键耐磨部件。它们形成破碎腔，原料如岩石、矿石和骨料通过机械压缩被破碎。这些板设计有波纹或光滑表面，以优化破碎效率和粒度减小。其几何形状、材料成分和齿形直接影响破碎机产能、产品级配以及采矿、采石和骨料生产中的运营成本。

颚板基于压缩破碎原理工作。活动颚板周期性地向固定颚板移动，形成逐渐变窄的间隙。进入破碎腔的物料通过两板之间施加的机械压力被破碎。板表面的波纹或齿形图案增强抓取和破碎效率，通过反复压缩循环将较大颗粒破碎成较小、均匀的尺寸。

Jaw plates operate on the principle of compressive crushing. The movable jaw plate moves cyclically toward the fixed jaw plate, creating a narrowing gap. Material fed into the chamber is crushed by the mechanical pressure exerted between the two plates. The corrugated or tooth patterns on the plate surfaces enhance grip and fracturing efficiency, breaking larger particles into smaller, uniform sizes through repeated compression cycles.
