Compound pendulum jaw crusher

复摆颚式破碎机是一种广泛应用于矿山、冶金、建材等行业的中小型破碎设备,主要用于对各类硬质物料(如花岗岩、玄武岩、石灰石等)进行粗碎或中碎作业。其核心工作原理基于复摆运动机构,通过动颚的周期性往复运动实现物料的挤压、劈裂和破碎。结构与工作原理 复摆颚式破碎机主要由机架、固定颚板、活动颚板、偏心轴、连杆、肘板等部件组成。动颚通过偏心轴直接驱动,上部悬挂在轴上,下部与肘板相连,形成复摆运动轨迹。当电机带动偏心轴旋转时,动颚既做横向摆动又做纵向升降运动,使物料在破碎腔内受到反复挤压和研磨。这种复合运动模式相比简摆式颚破,能同时实现水平与垂直方向的破碎力,提升破碎效率并减少能耗。性能特点 1. 高效破碎:复摆运动使动颚各点轨迹呈椭圆形,对物料施加多向力,破碎比大(通常为4-6),成品粒度均匀。 2. 结构简化:省去了简摆式破碎机的冗余连杆结构,整体重量减轻30%-40%,维护成本更低。 3. 节能环保:动颚下端行程较大,排料口调节灵活,可减少过粉碎现象,降低能耗约15%-20%。 4. 适应性广:通过更换不同齿形的颚板,可处理抗压强度不超过320MPa的多种物料,适用于移动式或固定式生产线。 应用场景 该设备常用于砂石骨料生产、选矿厂初级破碎、建筑垃圾再生等领域,尤其适合中小规模生产线。其紧凑的设计和较高的处理能力(5-1500吨/小时)使其成为中硬物料破碎的理想选择。 维护要点 需定期检查颚板磨损、润滑轴承及调整肘板间隙,避免非破碎物(如金属块)进入腔体导致设备过载。现代机型多配备液压保护装置,可自动释放过载压力,提升运行稳定性。 复摆颚式破碎机凭借其结构简单、能耗低、维护便捷等优势,在工业破碎领域持续发挥重要作用,是中小型石料加工线的核心设备之一。
