颚式破碎机尽管有多种结构型式，但其工作原理是相同的，即通过动颚的周期性运动来破碎物料。在动颚绕悬挂心轴向固定颚摆动的过程中，位于两颚板间的物料便受到压碎、劈裂与弯曲等综合作用。开始时，压力较小，使物料的体积缩小，物料之间互相靠近、挤紧；当压力上升到超过物料所能承受的强度时，即发生破碎。反之，当动颚离开固定颚向相反方向摆动时，物料则靠自重向下运动。动颚的每一个周期性运动就使物料受到一次压碎作用，并向下排送一段距离。经过若干个周期后，被破碎的物料便从排料口排出机外。

用途

本破碎机适用于破碎抗压强度为2500公斤/厘米2以下的各种矿石或岩石。

产品特点

1. 经过近十年的应用及改进，充分说明该系列破碎机破碎*，经久耐用，经得起市场检验。

2 、超细碎产品中粒度于8mm所占比例达到50%

1. 无摩擦破碎，颚板寿命长，百吨矿石钢耗仅为2kg (包括残余衬板在内) ，一般鄂板寿命为45-60天。
2. 性价比高，与其他类型细碎机相比，价格低1/4-1/2，维护费用为1/3-1/5。
3. “多碎少磨”效益显著，相同磨机可以增加处理量15-30%。
4. 自主设计单独稀油站稀油润滑；安全传力臂过载保护。
