摘要：随着科技的进步和社会的发展，工业占据了越来越重要的地位。其中，很多场合都会要用到破碎机来破碎物料。破碎工作所要消耗的能量是巨大的，尤其是应用于金属和非金属以及矿石和化工原料，建筑原料的加工。并且破碎作业的效率并不高。使得能源消耗巨大的原因是因为在破碎物料的过程中产生了震动摩擦和发热等等现象。因而，研究如何让破碎机高效的完成破碎工作并尽量减少能源消耗的问题近年来为许多国内外机械专家所研究。他们着手于从理论到创新开发及改造已经普遍面世的设备，完成改变生产工艺流程的目的。
环锤冲击式破碎机的历史并不如颚式破碎机以及反击式破碎机长。它是一种新型的，高工作效率的冲击式破碎装备。可以说实在锤式破碎机的基础上改良优化的。所以他们两者的工作原理基本是共通的。简要的说来就是利用轴带动锤头做高速回转运动，对矿石造成冲击。使矿石沿着它自然的裂缝，层理面和节理面等等较脆弱的部分被破碎。圆盘上插入了销轴，用来将锤环套在上面，这样，当轴运转的时候销轴运转使环锤产生了离心力。可以使位于转子和篦板筛之间的物料继续受到压碎和磨碎的作用，进而完成破碎工作。转子上配置的环锤有平环和齿研两种，故对物料还有劈碎的作用，可以克服因湿煤造成的粘结堵塞现象。19747
本毕业论文设计的计算方法是在实验室的试验模型样机测试的基础上，参考了锤式破碎机和反击式破碎机参数的有关计算公式，初步提出了环锤破碎机的设计计算方法。

The Design of PCH - 1216 Ring Hammer Crusher Rotor
Abstract：Crushing is an essential part of the contemporary the rapid development of economy and society a industrial chain. In the chemical and various metals, non-metallic mineral raw materials and the process of building materials, crushing work consumes vast amounts of energy, and is a low efficiency operation. In the process of material crushing, because produce, fever, such as vibration and friction role, make a lot of energy consumption. And domestic outsiders for many years has been studying how to achieve energy saving, to efficiently complete the crushing process. From theoretical research innovation equipment (including the reconstruction of old equipment) to change production process..
Ring hammer impact crusher is a new and efficient impingement crushing equipment, it is the same as the basic working principle of hammer crusher, mainly using high speed rotating hammer impact ore, make its along the natural fractures and bedding plane and vulnerable parts such as joint plane and broken. Ring hammer impact crusher hammer rings due to set on the pin shaft, thus functioning, ring hammer produced by centrifugal force can make the material in between the rotor and sieve plate has the role of crushing and grinding. Rotor on the configuration of ring hammer has flat ring and gear research two kinds, the role of reason for material to hack broken, can be overcome by wet coal caking blocking phenomenon.
The calculation method of the design is in the laboratory test model of the prototype test, on the basis of reference of hammer crusher and counterattack crusher parameters related calculation formula, the design and calculation method of ring hammer crusher has been put forward.
