摘要破碎机是冶金、化工、矿山、电力、陶瓷、水泥、建筑和筑路等工业部门广泛应用的主要设备，每年有大量的原料和再利用的废料都需要进行粉碎处理。现就题目要求设计有关石灰石的反击式破碎机。综合考虑，本次设计选择单转子反击式破碎机，可针对不同的破碎粒度进行反击破碎。23572
本次设计的原型为PFK-1212型反击式破碎机。重点介绍了可逆反击式破碎机的工作原理和结构组成，同时还分析了可逆反击式破碎机的优缺点以及适用范围。然后对整个破碎机的结构进行了改进设计，其主要是对传动方式进行改进设计和反击板的设计进行改进，从而提高产品的可靠性和使用寿命。最后对整个破碎机的操作、安装、文护进行了详细的说明，可为煤矿企业的破碎机的选择和使用提供参考。

The Design Of The PFK-1212 Impact Crusher overall
Abstract
Impact crushers are applied to such each department as the cement plant , power plant ,etc. in a large amount, so its design has an extensive prospect and experience that can be used for reference. Its design essence is, formerly after total conceptual design, a design which points each main spare part , question of installing and making a reservation etc., and carry on the intensity to check and test to the specific part, and in relevant thematic parts, analysis of comparing question that the life-span of very beginning of the hammer lengthens in detail . In the design of each spare part , should include the choice , sureness , demand processed , structure craft satisfactory of the size of the material , and the demand for cooperating with other parts, etc.. When the intensity is checked , should use relevant formula , carry on the analysis of the dangerous position, need to check form , mapping , calculation ,etc.. Then to to install , work course , work situation after predict that carries on more overall inspection whole, give consideration to the question in such respects as maintaining and safety ,etc. at the same time . Finally , choose to analyze in machining accuracy , public errand to two groundwork parts, economy and dependability that the breaker said as to ensure is designed finally.
