Principle of operationthe ring hammer granular crusher makes use of impact hitting hammer rings cross mounted on the rotating rotor to crush materiel . after first crushed by impact force of hammer rings , the materiel is then pressed , sheared and ground between crushing plate and ringhammers to the required granular product which flows off the screen , and those uncrushed such s tramp iron , wood pieces , stone etc will be brought into the tramp iron trap . this crusher features little blast wind , less vibration andlong , service life of vulnerable 工作原理环锤式破碎机利用旋转的转子带动环锤对物料进行冲击破碎，被冲击后的物料又在环锤和破碎板、筛板之间受到压缩、剪切、碾磨作用，使物料达到所需的粒度，被破碎后的物料经筛板的栅孔落下，不能被破碎的铁块、木块、石块等经拨料板拨进除铁室.本机具有鼓风量小、振动值小，环锤等易损件寿命长等特点。
In order to solve the problem of the difficulty for the complicated shell in stripping away from the mould , the technical trait of the complicated shell has been analyzed , the twi - ejector using stripper plate and ejector sleeve has been designed , the mould operational principle and the structure trait have been discussed , and the die casting machine has been selected based on the swelling force calculation 摘要针对复杂壳体压铸件难以脱模的问题，分析了复杂壳体的工艺特性，设计了卸料板、推管二次推出压铸模，论述了模具工作原理和结构特点，并且通过胀型力的计算选择了压铸机。
The results indicate that the position of sensitive plates is located at the section of middle or upper in tower but not near by feeding plate , and the smaller reflux ratio , the closer overhead of distillation tower . accurate calculation for flash is solved using matlab , and the result is correct and reasonable . complicated multi - components distillation and crude distillation are simulated using chemcad , and results are reasonable about profiles of flow for vapor and liquid as well as temperature in the tower 数值分析的结果表明精馏塔灵敏板位置并不在进料板附近,而是位于精馏段的中上部,且回流比愈小,愈靠近塔顶;利用matlab实现了蒸馏过程的严格计算,与参考值比较,结果正确、合理;借助于chemcad进行常减压塔的稳态模拟计算,得出了流量和温度在塔内的分布,经过理论分析,结果合理,可为实际生产提供参考。
