jc系列颚式破碎机是南昌矿机引进国际先进技术和研究成果，成功研发的新一代产品。广泛应用于各类最坚硬和高磨蚀性矿物岩的破碎作业。
产品特点features
1.高产量、大破碎比、低磨耗及大进料块度
jc颚式破碎机深腔形对称破碎腔设计使得破碎机进料粒度、产量和破碎比实现了最大化。运动机构的设计和破碎机的运行速度相结合，使破碎机获得最大产量和颚板低磨耗。理想的破碎啮角确保物料破碎和顺利通过，使破碎比达到最大。
2.可靠的重型动颚总成
动颚采用高质量的铸钢制造，通过大型铸铁皮带轮和飞轮带动。锻造的重型偏心轴和采用skf或fag的优质大型调心滚子轴承，使破碎机具有超凡的可靠性。动颚头部配有一可更换的护板，有效保护动颚不受进料的冲击。
3.坚固的机体结构
机体框架由前端铸钢定颚、两侧轧钢板和后部铸钢调整座组成，全部采用对接爆缝，改善了钢板的受力情况。机架组焊后进行整体退火，使机架强度高，坚固耐用，结构简洁。
4.对称破碎腔
夹角18-22°对称破碎腔设计，定颚与动颚衬板相同，可实现互换。
5.楔块排矿口调整系统
机械或液压模块排矿口调整系统，比垫片调整系统更简单、更安全。
6.无地脚螺栓安装方式
良好的平衡性能使破碎机无需地脚螺栓安装，通过安装在破碎机支座底部和侧面的橡胶减振块便可实现破碎机正常工作，减缓振动冲击，避免损坏基础。
7.一体化电机安装
电机机座与破碎机机架一体安装，减少了破碎机的安装空间和三角带的长度使之基础简单，三角带的使用寿命更长，同时可配置标准的皮带轮安全罩和飞轮安全罩。
jc jaw crusher is successfully developed by nms through introduction of foreign advanced technology and research findings. it is widely used in various hard and abrasive rocks.
features
1.higher productivity, higher reduction ratio, larger feeding acceptance and less wearing
due to the optimal design of the deep v symmetric crushing chamber, and the design of motion structure combined with the crusher speed, the crusher obtains the max.feeding size, productivity, reduction ratio and less wearing, the excellent nip angle makes the smooth rock crushing with the reduction ratio up to maximum.
2.reliable & durable heavy-duty pitman assemble
the pitman is made of high quality cast steel, driven by the heavy-duty cast iron belt wheel and flying wheel. the heavy duty forging eccentric flying wheel shaft and skf or fag bearing make the crusher extraordinarily reliable. the pitman is equipped with one interchangeable protection plate, efficiently protect the pitman from the shock of the feeding material.
3.robust frame
robust frame is welded by the front cast steel fixed jaw, side rolling steel plates, and rear cast steel adjustment units. we improve the welding and the steel force as well, with end welding to avoid plate layer failure. after welding, the frame unit will be given one whole annealing, so that the frame is stronger, durable, reliable, and simpler.
4.deep symmetric crushing chamber
with nip angle of 18-22°，the fixed jaw and the pitman liner is the same and can be interchangeable.
5.css wedge adjustment system
mechanical or hydraulic wedge css adjustment system is simpler and safer than the spacer adjustment.
6.no anchor bolt foundations
no anchor bolt foundations is possible due to the good balance of the crusher. the crusher can operate by the cushion between rubber dampers and stoppers to efficiently absorb crushing load, avoid the damage to the crusher foundation.
7.an integral motor base
an integral motor base is mounted on the crusher frame to prolong v-belt life and save the mounting space, the foundation can be more simple, while the standard belt wheel and the flywheel cover can be used.
