摘要：反击式破碎机是在颚式破碎机基础上发展起来的，非常多的用在石灰石，砂岩，水泥熟料，烧粘土，石膏及煤等矿石的粉碎使用，所以，它的设计有着很广的前景和很多的可借用的经验。它的设计实质是，在总体的设计方法完成之后，就指每个主要零部件的设计、安装、定位等问题，并对有些零件来进行试验和强度校核。并且在有关专题里，对反击式破碎机的转子锤头寿命的延长进行了很详细的说明与分析。在每个零部件的设计里，要包含选择材料、确定尺寸、加工要求，满足结构工艺性，还有配合其他零件的要求等。在强度校核时，要运用的相关公式，进行危险部位的分析、查表、作图和计算等。并随后对整体进行安装、工作过程以及工作后的各方面的检查，同时兼顾到文修、保险装置等方面的问题，最后对主要工作零件的加工精度、公差选择进行分析，以保证破碎机最终设计的经济性和可靠性。35046

 PF - 1620 overall design of counterattack crusher
 Abstract:The impact crusher hammer crusher is developed on the basis of, a lot of application in limestone, sandstone, the cement clinker, burned clay, gypsum and coal, ore of broken use, so, it is designed to have a wide range of prospects and rich experience for reference. The essence of the design is, in the final design scheme of the overall, when you refer to all the main parts design, installation, orientation, and the inpidual parts strength check and test. And in the related project, to the impact crusher rotor hammer live longer carry out more detailed analysis. In all parts of the design, to include the material choice, the size of the sure, processing requirements, the structure of the technology to meet, and other components of the cooperation of requirements, etc. In the strength of checking is, to use the related formula, the analysis of the dangerous parts, check a watch, mapping and calculation, etc. And then on the overall for installation, working process and work all the way to check, and pay attention to the maintenance, insurance device, and other aspects of the problem, the last of the main parts of the machining accuracy, tolerance, the choice of analysis, in order to ensure that the crusher of the final design of economy and reliability.
